This port is a variant of the compal_e88 configuration with the small
|
|
|
|
|
change of enabling the IrDA serial console:
|
2013-05-05 01:57:02 +02:00
|
|
|
|
|
|
|
|
* CONFIG_SERIAL_IRDA_CONSOLE=y
|
|
|
|
|
|
|
|
|
|
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:
|
|
|
|
|
|
|
|
|
|
* Pirelli DPL-10 nsh_highram loaded via romload in osmocon
|
|
|
|
|
|
|
|
|
|
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
|
|
|
|
|
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
|
|
|
|
|
are needed from the osmocom-bb directory.
|
|
|
|
|
|
|
|
|
|
By default, NuttX will not 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).

JTAG and Alternative Serial Console
