Open source phone project: see http://wiki.openmoko.org/wiki/Main_Page for details.

Osmocom can be run directly on the phone. The communication flow is:

For details see [wiki:osmocon] and [wiki:CalypsoRomloader]. IP networking between the host and the phone must be set up.

== On the phone: ==

 * disable ogsmd, ousaged, ophoned via /etc/frameworkd.conf

 * prevented fsogsmd from accessing modem by commenting following variables in /etc/freesmartphone/conf/GTA02/fsogsmd.conf:

   * device_port

   * modem_access

 * check that nothing uses the modem: fuser /dev/ttySAC0

 * open three SSH terminals to the phone

 * transfer layer1.highram.bin and osmocon binary to the phone

 * in the first terminal, make L2 socket externally available via socat:

{{{

socat -v -x tcp-l:16661,reuseaddr,fork unix-connect:/tmp/osmocom_l2

}}}

 * in the second terminal, run osmocon:

{{{

./osmocon -i 13 -m romload -p /dev/ttySAC0 layer1.highram.bin

}}}

 * in the third terminal, turn power off/on:

{{{

echo 0 >/sys/bus/platform/devices/gta02-pm-gsm.0/power_on && echo 1 >/sys/bus/platform/devices/gta02-pm-gsm.0/power_on

}}}

== on the host machine ==

 * Connect the socket:

{{{

socat -v -x unix-l:/var/tmp/l2,fork  tcp:192.168.0.202:16661,fork

}}}

Note: 192.168.0.202 is default address of the device when you use shr linux distribution.

After this you can run various tools on host machine, for example:

{{{

./cell_log -s /var/tmp/l2 -l /var/tmp/osmocom.log

}}}
