-compal_e88

-==========

-

-This directory contains the board support for compal e88 phones.

-

-This port is based on patches contributed by Denis Carikli for both the

-compal e99 and e88. At the time of initial check-in, the following phones

-were tested:

-

-* motorolla c155 (compal e99) with the compalram and highram configuration

-* motorolla W220 (compal e88)

-* The openmoko freerunner baseband(compal e88)

-

-The patches were made by Alan Carvalho de Assis and Denis Carikli using

-the Stefan Richter's patches that can be found here:

-

-http://cgit.osmocom.org/cgit/nuttx-bb/log/?h=lputt%2Ftesting

-

-Osmocom-BB Dependencies and Sercomm

-===================================

-

-The build environment assumes that you have the osmocom-bb project

-directory at same level as the nuttx project:

-

-  |- nuttx

-  |- apps

-  `- osmocom-bb

-

-If you attempt to build this configuration without osmocom-bb, you will

-get compilation errors in drivers/sercomm due to header files that are

-needed from the osmocom-bb directory.

-

-By default, NuttX will use sercomm (HDLC protocol) to communicate with the

-host system. Sercomm is the transport used by osmocom-bb that runs on top

-of serial.  See http://bb.osmocom.org/trac/wiki/nuttx-bb/run for detailed

-the usage of nuttx with sercomm.

-

-Loading NuttX

-=============

-

-The osmocom-bb wiki describes how to load NuttX.  See

-http://bb.osmocom.org/trac/wiki/nuttx-bb for detailed information.

-The way that nuttx is loaded depends on the configuration (highram/compalram)

-and phone:

-

-o compalram is for the ramloader(for phone having a bootloader on flash)

-o highram is for phones having the romloader(if the phone has a bootrom)

-  or for loading in the ram trough a special loader(loaded first on ram

-  by talking to the ramloader) when having a ramloader(which can only

-  load 64k).
