This identifies the particular # processor architecture (CONFIG_ARCH_SIM). # 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_ARCH="sim" CONFIG_ARCH_SIM=y CONFIG_ARCH_BOARD="sim" CONFIG_ARCH_BOARD_SIM=y # # General OS setup # # CONFIG_APPS_DIR - Identifies the relative path to the directory # that builds the application to link with NuttX. Default: ../apps # CONFIG_DEBUG - enables built-in debug options # CONFIG_DEBUG_VERBOSE - enables verbose debug output # CONFIG_DEBUG_SYMBOLS - build without optimization and with # debug symbols (needed for use with a debugger). # CONFIG_HAVE_CXX - Enable support for C++ # CONFIG_HAVE_CXXINITIALIZE - The platform-specific logic includes support # for initialization of static C++ instances for this architecture # and for the selected toolchain (via up_cxxinitialize()). # CONFIG_MM_REGIONS - If the architecture includes multiple # regions of memory to allocate from, this specifies the # number of memory regions that the memory manager must # handle and enables the API mm_addregion(start, end); # CONFIG_ARCH_LOWPUTC - architecture supports low-level, boot # time console output # CONFIG_MSEC_PER_TICK - The default system timer is 100Hz # or MSEC_PER_TICK=10. This setting may be defined to # inform NuttX that the processor hardware is providing # system timer interrupts at some interrupt interval other # than 10 msec. # CONFIG_RR_INTERVAL - The round robin timeslice will be set # this number of milliseconds; Round robin scheduling can # be disabled by setting this value to zero. # CONFIG_SCHED_INSTRUMENTATION - enables instrumentation in # scheduler to monitor system performance # CONFIG_TASK_NAME_SIZE - Spcifies that maximum size of a # task name to save in the TCB. Useful if scheduler # instrumentation is selected. Set to zero to disable. # CONFIG_START_YEAR, CONFIG_START_MONTH, CONFIG_START_DAY - # Used to initialize the internal time logic. # CONFIG_GREGORIAN_TIME - Enables Gregorian time conversions. # You would only need this if you are concerned about accurate # time conversions in the past or in the distant future. # CONFIG_JULIAN_TIME - Enables Julian time conversions. You # would only need this if you are concerned about accurate # time conversion in the distand past. You must also define # CONFIG_GREGORIAN_TIME in order to use Julian time. # 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 # 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_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.

NOTE: Microsoft claims # patents on FAT long file name technology. Please read the # 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.

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 # threshold determines if/when it is worth erased the tail end of FLASH # and making it available for re-use (and possible over-wear). # Default: 8192. # CONFIG_FS_ROMFS - Enable ROMFS filesystem support # CONFIG_FS_RAMMAP - For file systems that do not support XIP, this # option will enable a limited form of memory mapping that is # implemented by copying whole files into memory. # CONFIG_FS_FAT=y CONFIG_FAT_LCNAMES=y CONFIG_FAT_LFN=n CONFIG_FAT_MAXFNAME=32 CONFIG_FS_NXFFS=n CONFIG_FS_ROMFS=y # # TCP/IP and UDP support via uIP # CONFIG_NET - Enable or disable all network features # CONFIG_NET_IPv6 - Build in support for IPv6 # CONFIG_NSOCKET_DESCRIPTORS - Maximum number of socket descriptors per task/thread. # CONFIG_NET_SOCKOPTS - Enable or disable support for socket options # CONFIG_NET_BUFSIZE - uIP buffer size # CONFIG_NET_TCP - TCP support on or off # CONFIG_NET_TCP_CONNS - Maximum number of TCP connections (all tasks) # CONFIG_NET_TCP_READAHEAD_BUFSIZE - Size of TCP read-ahead buffers # CONFIG_NET_NTCP_READAHEAD_BUFFERS - Number of TCP read-ahead buffers (may be zero) # CONFIG_NET_TCPBACKLOG - Incoming connections pend in a backlog until # accept() is called.
