This directory contains the board support for compal e86 phones. This port
|
|
|
|
|
is tested on the following phone:
|
|
|
|
|
|
|
|
|
|
* motorola c139 (compal e86) with flash configuration
|

|
|
|
|
|
|
|
|
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:

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, and that
|
2014-04-14 00:22:22 +02:00
|
|
|
you added support for sercomm in your configuration(CONFIG_SERCOMM_CONSOLE=y)
|
|
|
|
|
you will get compilation errors in drivers/sercomm due to header files that
|
2013-09-27 23:11:31 +02:00
|
|
|
are needed from the osmocom-bb directory.
|
|
|
|
|
|
2014-04-14 00:22:22 +02:00
|
|
|
By default, NuttX will not use sercomm (HDLC protocol) to communicate with
|
2013-09-27 23:11:31 +02:00
|
|
|
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.

Running NuttX From Flash
|
|
|
|
|
========================
|
|
|
|
|
|
|
|
|
|
Flash layout:
|
|
|
|
|
|
|
|
|
|
0x00000 - 0x02000 - original compal loader
|
|
|
|
|
0x02000 - 0x10000 - simple binary to jump to 0x10000 (jumper.e86loader.bin)
|
|
|
|
|
0x10000 - ??? - NuttX binary (nuttx.bin)
|
|
|
|
|
|
|
|
|
|
Using osmocon/osmoload, retrieve the compal loader, flash it and the
|
|
|
|
|
jumper.e86loader.bin as well as nuttx.bin.
|
|
|
|
|
|
|
|
|
|
The jumper app is a modified version of the menu app in osmocom-bb, branch
|
|
|
|
|
jolly/menu. The app disabled irqs (setup by compal loader?) and jumps to
|
|
|
|
|
0x10000. This app is submitted as a patch to osmocom-bb mailing list.

Loading NuttX (highram)
|
|
|
|
|
=======================
|
2013-09-27 23:11:31 +02:00
|
|
|
|
|
|
|
|
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).
