Shouldn't it be possible to reboot the GSM modem? As described on the flashing page: Power off the modem: r...@om-gta02:~# echo 0 >/sys/bus/platform/devices/neo1973-pm-gsm.0/power_on r...@om-gta02:~# echo 1 >/sys/bus/platform/devices/neo1973-pm-gsm.0/power_on r...@om-gta02:~# s3c24xx-gpio b7=0 r...@om-gta02:~# stty 0:4:18b2:8a00:0:0:7f:15:4:0:0:0:0:0:0:0:12:f:17:16:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0 -F /dev/ttySAC0 r...@om-gta02:~# stty 0:4:18b2:8a00:0:0:7f:15:4:0:0:0:0:0:0:0:12:f:17:16:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0 -F /dev/ttySAC0 r...@om-gta02:~# echo -en "a...@poff\r" >/dev/ttySAC0; sleep 1; echo -en "a...@poff\r" >/dev/ttySAC0 Then power it on again: r...@om-gta02:~# s3c24xx-gpio b7=1 The framework should be able to detect a battery hotswap and just force a modem reboot IMHO. Even better maybe to say 'I want to swap the battery' and power off the modem before removing the battery. -- Tobias PGP: http://9ac7e0bc.uguu.de _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
