To compile nuttx-bb with sercomm, do the following steps:
* Clone osmocom-bb and nuttx-bb, they must reside in the same directory and you shouldn't change the name of the osmocom-bb directory.
{{{
git clone git://git.osmocom.org/osmocom-bb
git clone git://git.osmocom.org/nuttx-bb
}}}
* Put the gnuarm(for 64bit) or the codesourcery(for 32bit)
in your path(there is a problem with gnuarm for 32bit).
* Compile osmocom-bb as usual
{{{
cd osmocom-bb/src
make
cd ../../
}}}
* Configure nuttx-bb:
{{{
cd nuttx-bb/nuttx/tools/
./configure.sh compal_e88/nsh_highram #for compal_e88( gta02 and Motorola W220).
./configure.sh compal_e99/nsh_highram #for compal_e99( motorolla c155 )
}}}
* Modify your configuration(nuttx/.config):
{{{
-CONFIG_SERCOMM_CONSOLE=n
+CONFIG_SERCOMM_CONSOLE=y
-CONFIG_STDIO_LINE_BUFFER=y
}}}
* compile nuttx-bb:
{{{
cd ../
make
}}}
* nuttx.bin is ready for beeing loaded like any other firmware (Loading nuttx-bb is not different from loading osmocom-bb, refer to [wiki:osmocon]) the pages related to osmocom-bb for informations on how to load a firmware in your phone.)
== Running ==
Once you loaded nuttx-bb you should see the following appearing on sercomm:
{{{
[...]

handle_write_block(): 1024 bytes (1024/1024)
handle_write_block(): Block 61 finished

Finished, sent 63 blocks in total

Checksum on phone side matches, let's branch to your code
Branching to 0x00820000

}}}
To interact with it run the loadwriter.py script that can be found in nuttx/drivers/sercomm/loadwriter.py in the nuttx sources.
{{{
sudo ./loadwriter.py
>help
}}}
will produce the following output on sercomm:
