-# CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
-# CONFIG_ARCH_CHIP_name - For use in C code
-# CONFIG_ARCH_BOARD - identifies the configs subdirectory and, hence,
-#   the board that supports the particular chip or SoC.
-# CONFIG_ARCH_BOARD_name - for use in C code
-# CONFIG_ENDIAN_BIG - define if big endian (default is little endian)
-# CONFIG_BOARD_LOOPSPERMSEC - for delay loops
-# CONFIG_DRAM_SIZE - Describes the installed DRAM.
-# CONFIG_DRAM_START - The start address of DRAM (physical)
-# CONFIG_ARCH_NOINTC - define if the architecture does not
-#   support an interrupt controller or otherwise cannot support
-#   APIs like up_enable_irq() and up_disable_irq().
-# CONFIG_ARCH_IRQPRIO - The ATMega128 does not support interrupt prioritization
-# CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
-#   stack. If defined, this symbol is the size of the interrupt
-#   stack in bytes.  If not defined, the user task stacks will be
-#   used during interrupt handling.
-# CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
-# CONFIG_ARCH_BOOTLOADER - Set if you are using a bootloader.
-# CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
-# CONFIG_ARCH_BUTTONS -  Enable support for buttons. Unique to board architecture.
-# CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
-#   cause a 100 second delay during boot-up.  This 100 second delay
-#   serves no purpose other than it allows you to calibrate
-# CONFIG_BOARD_LOOPSPERMSEC.  You simply use a stop watch to measure
-#   the 100 second delay then adjust CONFIG_BOARD_LOOPSPERMSEC until
-#   the delay actually is 100 seconds.

 # OS setup related to on-demand paging:
 #
-# CONFIG_PAGING - If set =y in your configation file, this setting will
-#   enable the on-demand paging feature as described in
-#   http://www.nuttx.org/NuttXDemandPaging.html.
-#
-# If CONFIG_PAGING is selected, then the following also apply:
-#
-# CONFIG_PAGING_PAGESIZE - The size of one managed page.  This must
-#   be a value supported by the processor's memory management unit.
-# CONFIG_PAGING_NLOCKED - This is the number of locked pages in the
-#   memory map.  The locked address region will then be from
-#   CONFIG_DRAM_VSTART through (CONFIG_DRAM_VSTART +
-#   CONFIG_PAGING_PAGESIZE*CONFIG_PAGING_NLOCKED)
-# CONFIG_PAGING_LOCKED_PBASE and CONFIG_PAGING_LOCKED_VBASE - These
-#   may be defined to determine the base address of the locked page
-#   regions.  If neither are defined, the logic will be set the bases
-#   to CONFIG_DRAM_START and CONFIG_DRAM_VSTART (i.e., it assumes
-#   that the base address of the locked region is at the beginning
-#   of RAM).
-#   NOTE:  In some architectures, it may be necessary to take some
-#   memory from the beginning of this region for vectors or for a
-#   page table. In such cases, CONFIG_PAGING_LOCKED_P/VBASE should
-#   take that into consideration to prevent overlapping the locked
-#   memory region and the system data at the beginning of SRAM.
-# CONFIG_PAGING_NPPAGED - This is the number of physical pages
-#   available to support the paged text region.  This paged region
-#   begins at (CONFIG_PAGING_LOCKED_PBASE + CONFIG_PAGING_PAGESIZE*CONFIG_PAGING_NPPAGED)
-#   and continues until (CONFIG_PAGING_LOCKED_PBASE + CONFIG_PAGING_PAGESIZE*(CONFIG_PAGING_NLOCKED +
-#   CONFIG_PAGING_NPPAGED)
-# CONFIG_PAGING_NVPAGED - This actual size of the paged text region
-#   (in pages).  This is also the number of virtual pages required to
-#   support the entire paged region. The on-demand paging feature is
-#   intended to support only the case where the virtual paged text
-#   area is much larger the available physical pages.  Otherwise, why
-#   would you enable on-demand paging?
-# CONFIG_PAGING_NDATA - This is the number of data pages in the memory
-#   map.  The data region will extend to the end of RAM unless overridden
-#   by a setting in the configuration file.
-#   NOTE:  In some architectures, it may be necessary to take some memory
-#   from the end of RAM for page tables or other system usage.  The
-#   configuration settings and linker directives must be cognizant of that:
-#   CONFIG_PAGING_NDATA should be defined to prevent the data region from
-#   extending all the way to the end of memory. 
-# CONFIG_PAGING_DEFPRIO - The default, minimum priority of the page fill
-#   worker thread.  The priority of the page fill work thread will be boosted
-#   boosted dynmically so that it matches the priority of the task on behalf
-#   of which it peforms the fill.  This defines the minimum priority that
-#   will be used. Default: 50.
-# CONFIG_PAGING_STACKSIZE - Defines the size of the allocated stack
-#   for the page fill worker thread. Default: 1024.
-# CONFIG_PAGING_BLOCKINGFILL - The architecture specific up_fillpage()
-#   function may be blocking or non-blocking.  If defined, this setting
-#   indicates that the up_fillpage() implementation will block until the
-#   transfer is completed. Default:  Undefined (non-blocking).
-# CONFIG_PAGING_WORKPERIOD - The page fill worker thread will wake periodically
-#   even if there is no mapping to do.  This selection controls that wake-up
-#   period (in microseconds).  This wake-up a failsafe that will handle any 
-#   cases where a single is lost (that would really be a bug and shouldn't
-#   happen!) and also supports timeouts for case of non-blocking, asynchronous
-#   fills (see CONFIG_PAGING_TIMEOUT_TICKS).
-# CONFIG_PAGING_TIMEOUT_TICKS - If defined, the implementation will monitor
-#   the (asynchronous) page fill logic.  If the fill takes longer than this
-#   number if microseconds, then a fatal error will be declared.
-#   Default: No timeouts monitored.
-#
-# Some architecture-specific settings.  Defaults are architecture specific.
-# If you don't know what you are doing, it is best to leave these undefined
-# and try the system defaults:

-#  (which runs at the lowest of priority and may not be appropriate
-#  if memory reclamation is of high priority).  If CONFIG_SCHED_WORKQUEUE
-#  is enabled, then the following options can also be used:
-# CONFIG_SCHED_WORKPRIORITY - The execution priority of the worker
-#  thread.  Default: 50
-# CONFIG_SCHED_WORKPERIOD - How often the worker thread checks for

-# CONFIG_SCHED_INSTRUMENTATION - enables instrumentation in 
-#   scheduler to monitor system performance
-# CONFIG_TASK_NAME_SIZE - Spcifies that maximum size of a

-# CONFIG_DEV_CONSOLE - Set if architecture-specific logic
-#   provides /dev/console.  Enables stdout, stderr, stdin.
-# CONFIG_DEV_LOWCONSOLE - Use the simple, low-level serial console
-#   driver (minimul support)
-# CONFIG_MUTEX_TYPES: Set to enable support for recursive and
-#   errorcheck mutexes. Enables pthread_mutexattr_settype().
-# CONFIG_PRIORITY_INHERITANCE : Set to enable support for priority
-#   inheritance on mutexes and semaphores. 
-# CONFIG_SEM_PREALLOCHOLDERS: This setting is only used if priority
-#   inheritance is enabled.  It defines the maximum number of
-#   different threads (minus one) that can take counts on a
-#   semaphore with priority inheritance support.  This may be 
-#   set to zero if priority inheritance is disabled OR if you
-#   are only using semaphores as mutexes (only one holder) OR
-#   if no more than two threads participate using a counting
-#   semaphore.
-# CONFIG_SEM_NNESTPRIO.  If priority inheritance is enabled,
-#   then this setting is the maximum number of higher priority
-#   threads (minus 1) than can be waiting for another thread
-#   to release a count on a semaphore.  This value may be set
-#   to zero if no more than one thread is expected to wait for
-#   a semaphore.
-# CONFIG_FDCLONE_DISABLE. Disable cloning of all file descriptors
-#   by task_create() when a new task is started.  If set, all

-# CONFIG_SDCLONE_DISABLE. Disable cloning of all socket
-#   desciptors by task_create() when a new task is started. If
-#   set, all sockets will appear to be closed in the new task.
-# CONFIG_SCHED_WORKQUEUE.  Create a dedicated "worker" thread to
-#  handle delayed processing from interrupt handlers.  This feature
-#  is required for some drivers but, if there are not complaints,
-#  can be safely disabled.  The worker thread also performs
-#  garbage collection -- completing any delayed memory deallocations
-#  from interrupt handlers.  If the worker thread is disabled,
-#  then that clean will be performed by the IDLE thread instead
-#  (which runs at the lowest of priority and may not be appropriate
-#  if memory reclamation is of high priority).  If CONFIG_SCHED_WORKQUEUE
-#  is enabled, then the following options can also be used:
-# CONFIG_SCHED_WORKPRIORITY - The execution priority of the worker
-#  thread.  Default: 50
-# CONFIG_SCHED_WORKPERIOD - How often the worker thread checks for

-#   Many URLs use ~username to indicate a user's home directory. thttpd
-#   provides two options for mapping this construct to an  actual filename.
-#   1) Map ~username to <prefix>/username. This is the recommended choice.
-#     Each user gets a subdirectory in the main web tree, and the tilde
-#     construct points there. The prefix could be something like "users",
-#     or it could be empty.
-#   2) Map ~username to <user's homedir>/<postfix>. The postfix would be
-#     the name of a subdirectory off of the user's actual home dir,
-#     something like "public_html".
-#   You can also leave both options undefined, and thttpd will not do
-#   anything special about tildes. Enabling both options is an error.
-#   Typical values, if they're defined, are "users" for

-#   disclaimer in the top-level COPYING file and only enable this
-#   feature if you understand these issues.
-# CONFIG_FAT_MAXFNAME - If CONFIG_FAT_LFN is defined, then the
-#   default, maximum long file name is 255 bytes.  This can eat up
-#   a lot of memory (especially stack space).  If you are willing
-#   to live with some non-standard, short long file names, then
-#   define this value.  A good choice would be the same value as
-#   selected for CONFIG_NAME_MAX which will limit the visibility
-#   of longer file names anyway.
-# CONFIG_FS_NXFFS: Enable NuttX FLASH file system (NXFF) support.
-# CONFIG_NXFFS_ERASEDSTATE: The erased state of FLASH.

-# CONFIG_NXFFS_PACKTHRESHOLD: When packing flash file data,
-#   don't both with file chunks smaller than this number of data bytes.
-#   Default: 32.
-# CONFIG_NXFFS_TAILTHRESHOLD: clean-up can either mean
-#   packing files together toward the end of the file or, if file are
-#   deleted at the end of the file, clean up can simply mean erasing
-#   the end of FLASH memory so that it can be re-used again.  However,
-#   doing this can also harm the life of the FLASH part because it can
-#   mean that the tail end of the FLASH is re-used too often. This

-# CONFIG_PRIORITY_INHERITANCE : Set to enable support for priority
-#   inheritance on mutexes and semaphores. 
-# CONFIG_SEM_PREALLOCHOLDERS: This setting is only used if priority
-#   inheritance is enabled.  It defines the maximum number of
-#   different threads (minus one) that can take counts on a
-#   semaphore with priority inheritance support.  This may be 
-#   set to zero if priority inheritance is disabled OR if you
-#   are only using semaphores as mutexes (only one holder) OR

-#   files/drivers will appear to be closed in the new task.
-# CONFIG_FDCLONE_STDIO. Disable cloning of all but the first

-#   when a new task is started. If set, all files/drivers will
-#   appear to be closed in the new task except for stdin, stdout,

-# CONFIG_NXFLAT. Enable support for the NXFLAT binary format.
-#  This format will support execution of NuttX binaries located

-# CONFIG_SCHED_WORKQUEUE.  Create a dedicated "worker" thread to
-#  handle delayed processing from interrupt handlers.  This feature
-#  is required for some drivers but, if there are not complaints,
-#  can be safely disabled.  The worker thread also performs
-#  garbage collection -- completing any delayed memory deallocations
-#  from interrupt handlers.  If the worker thread is disabled,
-#  then that clean will be performed by the IDLE thread instead
-#  (which runs at the lowest of priority and may not be appropriate
-#  if memory reclamation is of high priority).  If CONFIG_SCHED_WORKQUEUE
-#  is enabled, then the following options can also be used:
-# CONFIG_SCHED_WORKPRIORITY - The execution priority of the worker
-#  thread.  Default: 50
-# CONFIG_SCHED_WORKPERIOD - How often the worker thread checks for
-#  work in units of microseconds.  Default: 50000 (50 MS).

-# CONFIG_FAT_MAXFNAME - If CONFIG_FAT_LFN is defined, then the

-#   a lot of memory (especially stack space).  If you are willing
-#   to live with some non-standard, short long file names, then

-#   deleted at the end of the file, clean up can simply mean erasing
-#   the end of FLASH memory so that it can be re-used again.  However,
-#   doing this can also harm the life of the FLASH part because it can

 # NxConsole Configuration Settings:
 #
-# CONFIG_NXCONSOLE
-#   Enables building of the NxConsole driver.
-# CONFIG_NXCONSOLE_BPP
-#   Currently, NxConsole supports only a single pixel depth. This
-#   configuration setting must be provided to support that single pixel depth.
-#   Default: The smallest enabled pixel depth. (see CONFIG_NX_DISABLE_*BPP)
-# CONFIG_NXCONSOLE_MXCHARS
-#   NxConsole needs to remember every character written to the console so
-#   that it can redraw the window. This setting determines the size of some
-#   internal memory allocations used to hold the character data. Default: 128.
-# CONFIG_NXCONSOLE_CACHESIZE
-#   NxConsole supports caching of rendered fonts. This font caching is required
-#   for two reasons: (1) First, it improves text performance, but more
-#   importantly (2) it preserves the font memory. Since the NX server runs on
-#   a separate server thread, it requires that the rendered font memory persist
-#   until the server has a chance to render the font. (NOTE: There is still
-#   inherently a race condition in this!). Unfortunately, the font cache would
-#   be quite large if all fonts were saved. The CONFIG_NXCONSOLE_CACHESIZE setting
-#   will control the size of the font cache (in number of glyphs). Only that
-#   number of the most recently used glyphs will be retained. Default: 16.
-# CONFIG_NXCONSOLE_LINESEPARATION
-#   This the space (in rows) between each row of test.  Default: 2
-# CONFIG_NXCONSOLE_NOWRAP
-#   By default, lines will wrap when the test reaches the right hand side
-#   of the window. This setting can be defining to change this behavior so
-#   that the text is simply truncated until a new line is  encountered.

-# CONFIG_ARCH - identifies the arch subdirectory and, hence, the
-#   processor architecture.
-# CONFIG_ARCH_family - for use in C code.  This identifies the
-#   particular chip family that the architecture is implemented
-#   in.
-# CONFIG_ARCH_architecture - for use in C code.  This identifies the
-#   specific architecture within the chip family.
-# CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
-# CONFIG_ARCH_CHIP_name - For use in C code
-# CONFIG_ARCH_BOARD - identifies the configs subdirectory and, hence,
-#   the board that supports the particular chip or SoC.
-# CONFIG_ARCH_BOARD_name - for use in C code
-# CONFIG_ENDIAN_BIG - define if big endian (default is little endian)
-#   NOTE: The PIC32MX is always little endian.
-# CONFIG_BOARD_LOOPSPERMSEC.  You simply use a stop watch to measure
-#   the 100 second delay then adjust CONFIG_BOARD_LOOPSPERMSEC until
-#   the delay actually is 100 seconds.
-# CONFIG_DRAM_SIZE - Describes the installed DRAM.
-# CONFIG_DRAM_START - The start address of DRAM (physical)
-# CONFIG_ARCH_NOINTC - define if the architecture does not
-#   support an interrupt controller or otherwise cannot support
-#   APIs like up_enable_irq() and up_disable_irq().
-# CONFIG_ARCH_VECNOTIRQ - Usually the interrupt vector number provided
-#   to interfaces like irq_attach() and irq_detach are the same as IRQ
-#   numbers that are provied to IRQ management functions like
-#   up_enable_irq() and up_disable_irq().  But that is not true for all
-#   interrupt controller implementations.  For example, the PIC32MX
-#   interrupt controller manages interrupt sources that have a many-to-one
-#   relationship to interrupt vectors. In such cases, CONFIG_ARCH_VECNOTIRQ
-#   must defined so that the OS logic will know not to assume it can use
-#   a vector number to enable or disable interrupts.
-# CONFIG_ARCH_IRQPRIO - The PIC32MX supports interrupt prioritization
-# CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
-#   stack. If defined, this symbol is the size of the interrupt
-#   stack in bytes.  If not defined, the user task stacks will be
-#   used during interrupt handling.
-# CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
-# CONFIG_ARCH_BOOTLOADER - Set if you are using a bootloader.
-# CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
-# CONFIG_ARCH_BUTTONS -  Enable support for buttons. Unique to board architecture.
-# CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
-#   cause a 100 second delay during boot-up.  This 100 second delay
-#   serves no purpose other than it allows you to calibrate
-# CONFIG_ARCH_DMA - Support DMA initialization

 # NxConsole Configuration Settings:

-# CONFIG_NXCONSOLE
-#   Enables building of the NxConsole driver.
-# CONFIG_NXCONSOLE_BPP
-#   Currently, NxConsole supports only a single pixel depth. This
-#   configuration setting must be provided to support that single pixel depth.
-#   Default: The smallest enabled pixel depth. (see CONFIG_NX_DISABLE_*BPP)
-# CONFIG_NXCONSOLE_MXCHARS
-#   NxConsole needs to remember every character written to the console so
-#   that it can redraw the window. This setting determines the size of some
-#   internal memory allocations used to hold the character data. Default: 128.
-# CONFIG_NXCONSOLE_CACHESIZE
-#   NxConsole supports caching of rendered fonts. This font caching is required
-#   for two reasons: (1) First, it improves text performance, but more
-#   importantly (2) it preserves the font memory. Since the NX server runs on
-#   a separate server thread, it requires that the rendered font memory persist
-#   until the server has a chance to render the font. (NOTE: There is still
-#   inherently a race condition in this!). Unfortunately, the font cache would
-#   be quite large if all fonts were saved. The CONFIG_NXCONSOLE_CACHESIZE setting
-#   will control the size of the font cache (in number of glyphs). Only that
-#   number of the most recently used glyphs will be retained. Default: 16.
-# CONFIG_NXCONSOLE_LINESEPARATION
-#   This the space (in rows) between each row of test.  Default: 2
-# CONFIG_NXCONSOLE_NOWRAP
-#   By default, lines will wrap when the test reaches the right hand side
-#   of the window. This setting can be defining to change this behavior so
-#   that the text is simply truncated until a new line is  encountered.

 # NxConsole Configuration Settings:
 #
-# CONFIG_NXCONSOLE
-#   Enables building of the NxConsole driver.
-# CONFIG_NXCONSOLE_BPP
-#   Currently, NxConsole supports only a single pixel depth. This
-#   configuration setting must be provided to support that single pixel depth.
-#   Default: The smallest enabled pixel depth. (see CONFIG_NX_DISABLE_*BPP)
-# CONFIG_NXCONSOLE_MXCHARS
-#   NxConsole needs to remember every character written to the console so
-#   that it can redraw the window. This setting determines the size of some
-#   internal memory allocations used to hold the character data. Default: 128.
-# CONFIG_NXCONSOLE_CACHESIZE
-#   NxConsole supports caching of rendered fonts. This font caching is required
-#   for two reasons: (1) First, it improves text performance, but more
-#   importantly (2) it preserves the font memory. Since the NX server runs on
-#   a separate server thread, it requires that the rendered font memory persist
-#   until the server has a chance to render the font. (NOTE: There is still
-#   inherently a race condition in this!). Unfortunately, the font cache would
-#   be quite large if all fonts were saved. The CONFIG_NXCONSOLE_CACHESIZE setting
-#   will control the size of the font cache (in number of glyphs). Only that
-#   number of the most recently used glyphs will be retained. Default: 16.
-# CONFIG_NXCONSOLE_LINESEPARATION
-#   This the space (in rows) between each row of test.  Default: 2
-# CONFIG_NXCONSOLE_NOWRAP
-#   By default, lines will wrap when the test reaches the right hand side
-#   of the window. This setting can be defining to change this behavior so
-#   that the text is simply truncated until a new line is  encountered.

-#   for two reasons: (1) First, it improves text performance, but more
-#   importantly (2) it preserves the font memory. Since the NX server runs on
-#   a separate server thread, it requires that the rendered font memory persist
-#   until the server has a chance to render the font. (NOTE: There is still
-#   inherently a race condition in this!). Unfortunately, the font cache would
-#   be quite large if all fonts were saved. The CONFIG_NXCONSOLE_CACHESIZE setting
-#   will control the size of the font cache (in number of glyphs). Only that
-#   number of the most recently used glyphs will be retained. Default: 16.
-# CONFIG_NXCONSOLE_LINESEPARATION
-#   This the space (in rows) between each row of test.  Default: 2
-# CONFIG_NXCONSOLE_NOWRAP
-#   By default, lines will wrap when the test reaches the right hand side
-#   of the window. This setting can be defining to change this behavior so
-#   that the text is simply truncated until a new line is  encountered.

-# CONFIG_NXCONSOLE_BPP
-#   Currently, NxConsole supports only a single pixel depth. This

-#   Default: The smallest enabled pixel depth. (see CONFIG_NX_DISABLE_*BPP)
-# CONFIG_NXCONSOLE_MXCHARS
-#   NxConsole needs to remember every character written to the console so
-#   that it can redraw the window. This setting determines the size of some
-#   internal memory allocations used to hold the character data. Default: 128.
-# CONFIG_NXCONSOLE_CACHESIZE
-#   NxConsole supports caching of rendered fonts. This font caching is required
-#   for two reasons: (1) First, it improves text performance, but more
-#   importantly (2) it preserves the font memory. Since the NX server runs on
-#   a separate server thread, it requires that the rendered font memory persist
-#   until the server has a chance to render the font. (NOTE: There is still
-#   inherently a race condition in this!). Unfortunately, the font cache would
-#   be quite large if all fonts were saved. The CONFIG_NXCONSOLE_CACHESIZE setting
-#   will control the size of the font cache (in number of glyphs). Only that
-#   number of the most recently used glyphs will be retained. Default: 16.
-# CONFIG_NXCONSOLE_LINESEPARATION
-#   This the space (in rows) between each row of test.  Default: 2
-# CONFIG_NXCONSOLE_NOWRAP
-#   By default, lines will wrap when the test reaches the right hand side

-# CONFIG_NXCONSOLE_MXCHARS
-#   NxConsole needs to remember every character written to the console so
-#   that it can redraw the window. This setting determines the size of some
-#   internal memory allocations used to hold the character data. Default: 128.
-# CONFIG_NXCONSOLE_CACHESIZE
-#   NxConsole supports caching of rendered fonts. This font caching is required
-#   for two reasons: (1) First, it improves text performance, but more
-#   importantly (2) it preserves the font memory. Since the NX server runs on
-#   a separate server thread, it requires that the rendered font memory persist
-#   until the server has a chance to render the font. (NOTE: There is still
-#   inherently a race condition in this!). Unfortunately, the font cache would
-#   be quite large if all fonts were saved. The CONFIG_NXCONSOLE_CACHESIZE setting
-#   will control the size of the font cache (in number of glyphs). Only that
-#   number of the most recently used glyphs will be retained. Default: 16.
-# CONFIG_NXCONSOLE_LINESEPARATION
-#   This the space (in rows) between each row of test.  Default: 2
-# CONFIG_NXCONSOLE_NOWRAP
-#   By default, lines will wrap when the test reaches the right hand side

-# CONFIG_NXCONSOLE_BPP
-#   Currently, NxConsole supports only a single pixel depth. This

-#   Default: The smallest enabled pixel depth. (see CONFIG_NX_DISABLE_*BPP)
-# CONFIG_NXCONSOLE_MXCHARS
-#   NxConsole needs to remember every character written to the console so
-#   that it can redraw the window. This setting determines the size of some
-#   internal memory allocations used to hold the character data. Default: 128.
-# CONFIG_NXCONSOLE_CACHESIZE
-#   NxConsole supports caching of rendered fonts. This font caching is required
-#   for two reasons: (1) First, it improves text performance, but more
-#   importantly (2) it preserves the font memory. Since the NX server runs on
-#   a separate server thread, it requires that the rendered font memory persist
-#   until the server has a chance to render the font. (NOTE: There is still
-#   inherently a race condition in this!). Unfortunately, the font cache would
-#   be quite large if all fonts were saved. The CONFIG_NXCONSOLE_CACHESIZE setting
-#   will control the size of the font cache (in number of glyphs). Only that
-#   number of the most recently used glyphs will be retained. Default: 16.
-# CONFIG_NXCONSOLE_LINESEPARATION
-#   This the space (in rows) between each row of test.  Default: 2
-# CONFIG_NXCONSOLE_NOWRAP
-#   By default, lines will wrap when the test reaches the right hand side

-# CONFIG_FAT_MAXFNAME - If CONFIG_FAT_LFN is defined, then the

-#   Default: 32.
-# CONFIG_NXFFS_TAILTHRESHOLD: clean-up can either mean
-#   packing files together toward the end of the file or, if file are
-#   deleted at the end of the file, clean up can simply mean erasing
-#   the end of FLASH memory so that it can be re-used again.  However,
-#   doing this can also harm the life of the FLASH part because it can
-#   mean that the tail end of the FLASH is re-used too often. This

-#   NxConsole supports caching of rendered fonts. This font caching is required
-#   for two reasons: (1) First, it improves text performance, but more

-#   a separate server thread, it requires that the rendered font memory persist
-#   until the server has a chance to render the font. (NOTE: There is still
-#   inherently a race condition in this!). Unfortunately, the font cache would
-#   be quite large if all fonts were saved. The CONFIG_NXCONSOLE_CACHESIZE setting

 # RTC Configuration
 #
-# CONFIG_RTC - Enables general support for a hardware RTC.  Specific

-# CONFIG_RTC_DATETIME - There are two general types of RTC:  (1) A simple
-#   battery backed counter that keeps the time when power is down, and (2)
-#    A full date / time RTC the provides the date and time information, often
-#   in BCD format.  If CONFIG_RTC_DATETIME is selected, it specifies this
-#   second kind of RTC. In this case, the RTC is used to "seed" the normal
-#   NuttX timer and the NuttX system timer provides for higher resoution
-#   time.
-# CONFIG_RTC_HIRES - If CONFIG_RTC_DATETIME not selected, then the simple,
-#   battery backed counter is used.  There are two different implementations
-#   of such simple counters based on the time resolution of the counter:
-#   The typical RTC keeps time to resolution of 1 second, usually
-#   supporting a 32-bit time_t value.  In this case, the RTC is used to
-#   "seed" the normal NuttX timer and the NuttX timer provides for higher
-#   resoution time. If CONFIG_RTC_HIRES is enabled in the NuttX configuration,
-#   then the RTC provides higher resolution time and completely replaces the
-#   system timer for purpose of date and time.
-# CONFIG_RTC_FREQUENCY - If CONFIG_RTC_HIRES is defined, then the frequency
-#  of the high resolution RTC must be provided.  If CONFIG_RTC_HIRES is
-#   not defined, CONFIG_RTC_FREQUENCY is assumed to be one.
-# CONFIG_RTC_ALARM - Enable if the RTC hardware supports setting of an
-#  alarm.  A callback function will be executed when the alarm goes off

-#   NxConsole supports caching of rendered fonts. This font caching is required

-# CONFIG_NXCONSOLE_BPP
-#   Currently, NxConsole supports only a single pixel depth. This

-#   Default: The smallest enabled pixel depth. (see CONFIG_NX_DISABLE_*BPP)
-# CONFIG_NXCONSOLE_MXCHARS
-#   NxConsole needs to remember every character written to the console so
-#   that it can redraw the window. This setting determines the size of some
-#   internal memory allocations used to hold the character data. Default: 128.
-# CONFIG_NXCONSOLE_CACHESIZE
-#   NxConsole supports caching of rendered fonts. This font caching is required
-#   for two reasons: (1) First, it improves text performance, but more
-#   importantly (2) it preserves the font memory. Since the NX server runs on
-#   a separate server thread, it requires that the rendered font memory persist
-#   until the server has a chance to render the font. (NOTE: There is still
-#   inherently a race condition in this!). Unfortunately, the font cache would
-#   be quite large if all fonts were saved. The CONFIG_NXCONSOLE_CACHESIZE setting
-#   will control the size of the font cache (in number of glyphs). Only that
-#   number of the most recently used glyphs will be retained. Default: 16.
-# CONFIG_NXCONSOLE_LINESEPARATION
-#   This the space (in rows) between each row of test.  Default: 2
-# CONFIG_NXCONSOLE_NOWRAP
-#   By default, lines will wrap when the test reaches the right hand side

 # NxConsole Configuration Settings:
 #
-# CONFIG_NXCONSOLE
-#   Enables building of the NxConsole driver.
-# CONFIG_NXCONSOLE_BPP
-#   Currently, NxConsole supports only a single pixel depth. This
-#   configuration setting must be provided to support that single pixel depth.
-#   Default: The smallest enabled pixel depth. (see CONFIG_NX_DISABLE_*BPP)
-# CONFIG_NXCONSOLE_MXCHARS
-#   NxConsole needs to remember every character written to the console so
-#   that it can redraw the window. This setting determines the size of some
-#   internal memory allocations used to hold the character data. Default: 128.
-# CONFIG_NXCONSOLE_CACHESIZE
-#   NxConsole supports caching of rendered fonts. This font caching is required
-#   for two reasons: (1) First, it improves text performance, but more
-#   importantly (2) it preserves the font memory. Since the NX server runs on
-#   a separate server thread, it requires that the rendered font memory persist
-#   until the server has a chance to render the font. (NOTE: There is still
-#   inherently a race condition in this!). Unfortunately, the font cache would
-#   be quite large if all fonts were saved. The CONFIG_NXCONSOLE_CACHESIZE setting
-#   will control the size of the font cache (in number of glyphs). Only that
-#   number of the most recently used glyphs will be retained. Default: 16.
-# CONFIG_NXCONSOLE_LINESEPARATION
-#   This the space (in rows) between each row of test.  Default: 2
-# CONFIG_NXCONSOLE_NOWRAP
-#   By default, lines will wrap when the test reaches the right hand side
-#   of the window. This setting can be defining to change this behavior so
-#   that the text is simply truncated until a new line is  encountered.

-# CONFIG_NXCONSOLE_MXCHARS

-# CONFIG_NXCONSOLE_CACHESIZE
-#   NxConsole supports caching of rendered fonts. This font caching is required
-#   for two reasons: (1) First, it improves text performance, but more
-#   importantly (2) it preserves the font memory. Since the NX server runs on
-#   a separate server thread, it requires that the rendered font memory persist
-#   until the server has a chance to render the font. (NOTE: There is still
-#   inherently a race condition in this!). Unfortunately, the font cache would
-#   be quite large if all fonts were saved. The CONFIG_NXCONSOLE_CACHESIZE setting

-# CONFIG_NXCONSOLE
-#   Enables building of the NxConsole driver.
-# CONFIG_NXCONSOLE_BPP
-#   Currently, NxConsole supports only a single pixel depth. This
-#   configuration setting must be provided to support that single pixel depth.
-#   Default: The smallest enabled pixel depth. (see CONFIG_NX_DISABLE_*BPP)
-# CONFIG_NXCONSOLE_MXCHARS
-#   NxConsole needs to remember every character written to the console so
-#   that it can redraw the window. This setting determines the size of some
-#   internal memory allocations used to hold the character data. Default: 128.
-# CONFIG_NXCONSOLE_CACHESIZE
-#   NxConsole supports caching of rendered fonts. This font caching is required
-#   for two reasons: (1) First, it improves text performance, but more
-#   importantly (2) it preserves the font memory. Since the NX server runs on
-#   a separate server thread, it requires that the rendered font memory persist
-#   until the server has a chance to render the font. (NOTE: There is still
-#   inherently a race condition in this!). Unfortunately, the font cache would
-#   be quite large if all fonts were saved. The CONFIG_NXCONSOLE_CACHESIZE setting
-#   will control the size of the font cache (in number of glyphs). Only that
-#   number of the most recently used glyphs will be retained. Default: 16.
-# CONFIG_NXCONSOLE_LINESEPARATION
-#   This the space (in rows) between each row of test.  Default: 2
-# CONFIG_NXCONSOLE_NOWRAP
-#   By default, lines will wrap when the test reaches the right hand side
-#   of the window. This setting can be defining to change this behavior so

-# CONFIG_RTC_DATETIME - There are two general types of RTC:  (1) A simple
-#   battery backed counter that keeps the time when power is down, and (2)
-#    A full date / time RTC the provides the date and time information, often
-#   in BCD format.  If CONFIG_RTC_DATETIME is selected, it specifies this
-#   second kind of RTC. In this case, the RTC is used to "seed" the normal
-#   NuttX timer and the NuttX system timer provides for higher resoution
-#   time.
-# CONFIG_RTC_HIRES - If CONFIG_RTC_DATETIME not selected, then the simple,
-#   battery backed counter is used.  There are two different implementations
-#   of such simple counters based on the time resolution of the counter:
-#   The typical RTC keeps time to resolution of 1 second, usually
-#   supporting a 32-bit time_t value.  In this case, the RTC is used to
-#   "seed" the normal NuttX timer and the NuttX timer provides for higher
-#   resoution time. If CONFIG_RTC_HIRES is enabled in the NuttX configuration,
-#   then the RTC provides higher resolution time and completely replaces the
-#   system timer for purpose of date and time.
-# CONFIG_RTC_FREQUENCY - If CONFIG_RTC_HIRES is defined, then the frequency
-#  of the high resolution RTC must be provided.  If CONFIG_RTC_HIRES is
-#   not defined, CONFIG_RTC_FREQUENCY is assumed to be one.

-# CONFIG_ARCH - identifies the arch subdirectory and, hence, the
-#   processor architecture.
-# CONFIG_ARCH_family - for use in C code.  This identifies the
-#   particular chip family that the architecture is implemented
-#   in.
-# CONFIG_ARCH_architecture - for use in C code.  This identifies the
-#   specific architecture within the chip family.
-# CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
-# CONFIG_ARCH_CHIP_name - For use in C code
-# CONFIG_ARCH_BOARD - identifies the configs subdirectory and, hence,
-#   the board that supports the particular chip or SoC.
-# CONFIG_ARCH_BOARD_name - for use in C code
-# CONFIG_ENDIAN_BIG - define if big endian (default is little endian)
-#   NOTE: The PIC32MX is always little endian.
-# CONFIG_BOARD_LOOPSPERMSEC.  You simply use a stop watch to measure
-#   the 100 second delay then adjust CONFIG_BOARD_LOOPSPERMSEC until
-#   the delay actually is 100 seconds.
-# CONFIG_DRAM_SIZE - Describes the installed DRAM.
-# CONFIG_DRAM_START - The start address of DRAM (physical)
-# CONFIG_ARCH_NOINTC - define if the architecture does not
-#   support an interrupt controller or otherwise cannot support
-#   APIs like up_enable_irq() and up_disable_irq().
-# CONFIG_ARCH_VECNOTIRQ - Usually the interrupt vector number provided
-#   to interfaces like irq_attach() and irq_detach are the same as IRQ
-#   numbers that are provied to IRQ management functions like
-#   up_enable_irq() and up_disable_irq().  But that is not true for all
-#   interrupt controller implementations.  For example, the PIC32MX
-#   interrupt controller manages interrupt sources that have a many-to-one
-#   relationship to interrupt vectors. In such cases, CONFIG_ARCH_VECNOTIRQ
-#   must defined so that the OS logic will know not to assume it can use
-#   a vector number to enable or disable interrupts.
-# CONFIG_ARCH_IRQPRIO - The PIC32MX supports interrupt prioritization
-# CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
-#   stack. If defined, this symbol is the size of the interrupt
-#   stack in bytes.  If not defined, the user task stacks will be
-#   used during interrupt handling.
-# CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
-# CONFIG_ARCH_BOOTLOADER - Set if you are using a bootloader.
-# CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
-# CONFIG_ARCH_BUTTONS -  Enable support for buttons. Unique to board architecture.
-# CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
-#   cause a 100 second delay during boot-up.  This 100 second delay
-#   serves no purpose other than it allows you to calibrate
-# CONFIG_ARCH_DMA - Support DMA initialization

-# CONFIG_SEM_PREALLOCHOLDERS: This setting is only used if priority
-#   inheritance is enabled.  It defines the maximum number of
-#   different threads (minus one) that can take counts on a
-#   semaphore with priority inheritance support.  This may be 
-#   set to zero if priority inheritance is disabled OR if you
-#   are only using semaphores as mutexes (only one holder) OR
-#   if no more than two threads participate using a counting
-#   semaphore.
-# CONFIG_SEM_NNESTPRIO.  If priority inheritance is enabled,
-#   then this setting is the maximum number of higher priority
-#   threads (minus 1) than can be waiting for another thread
-#   to release a count on a semaphore.  This value may be set
-#   to zero if no more than one thread is expected to wait for
-#   a semaphore.
-# CONFIG_FDCLONE_DISABLE. Disable cloning of all file descriptors
-#   by task_create() when a new task is started.  If set, all
-#   files/drivers will appear to be closed in the new task.
-# CONFIG_FDCLONE_STDIO. Disable cloning of all but the first
-#   three file descriptors (stdin, stdout, stderr) by task_create()
-#   when a new task is started. If set, all files/drivers will
-#   appear to be closed in the new task except for stdin, stdout,
-#   and stderr.
-# CONFIG_SDCLONE_DISABLE. Disable cloning of all socket
-#   desciptors by task_create() when a new task is started. If
-#   set, all sockets will appear to be closed in the new task.
-# CONFIG_NXFLAT. Enable support for the NXFLAT binary format.
-#  This format will support execution of NuttX binaries located
-#  in a ROMFS filesystem (see examples/nxflat).
-# CONFIG_SCHED_WORKQUEUE.  Create a dedicated "worker" thread to
-#  handle delayed processing from interrupt handlers.  This feature
-#  is required for some drivers but, if there are not complaints,
-#  can be safely disabled.  The worker thread also performs
-#  garbage collection--completing any delayed memory deallocations
-#  from interrupt handlers.  If the worker thread is disabled,
-#  then that clean will be performed by the IDLE thread instead
-#  (which runs at the lowest of priority and may not be appropriate
-#  if memory reclamation is of high priority).  If CONFIG_SCHED_WORKQUEUE
-#  is enabled, then the following options can also be used:
-# CONFIG_SCHED_WORKPRIORITY - The execution priority of the worker
-#  thread.  Default: 50
-# CONFIG_SCHED_WORKPERIOD - How often the worker thread checks for
-#  work in units of microseconds.  Default: 50000 (50 MS).
-# CONFIG_SCHED_WORKSTACKSIZE - The stack size allocated for the worker
-#  thread.  Default: CONFIG_IDLETHREAD_STACKSIZE.
-# CONFIG_SIG_SIGWORK - The signal number that will be used to wake-up
-#  the worker thread.  Default: 4
