Added link to osmocon.


To compile nuttx-bb with sercomm, do the following steps: {{{
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
}}} {{{
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])

  • compile nuttx-bb:
Running
Once you loaded nuttx-bb you should see the following appearing on sercomm: {{{
[...]

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: {{{
