Re: about osmocon on gta02 (Solved)
by Aegean Chou 14 Jun '12

14 Jun '12

Hi lists, I spend one day, finally solved it myself. 1) i checked the schematic of gta02 carefully, and found the PCF50633 use GPIO2(gsm_on) to control the power of GSM actually, and it have a test point H-TP1706. 2) i disassembled my gta02, then line out the H-TP1706 to my oscilloscope, i found the gsm_on signal always LOW 1s, and HIGH 4.2s, it's very strange. 3) i checked the service list, i found the fsogsmd (it's ogsmd?), maybe it's the background program. but i can't kill it. 4) finally, i try to set "disable = 0" in /etc/frameworkd.conf, reboot, my god, it solved. but the http://bb.osmocom.org/trac/wiki/OpenMoko only says: “disable ogsmd, ousaged, ophoned via /etc/frameworkd.conf” i always think "disable = 1" should DISABLE it. but actually, "disable = 0" = DISABLE it; and "disable = 1" = ENABLE it? why it misleaded me so long, anybody can change it? thanks.

about osmocon on gta02
by Aegean Chou 14 Jun '12

14 Jun '12

Dear lists, i want porting rssi and osmocon to GTA02, let them run on GTA02 stand-alone. then i'll try to write a program to decoding the received data. i already cross-compiled the latest osmocon to GTA02, then i disabled "ogsmd，ousaged and ophoned" in /etc/frameworkd.conf (actually, them are disabled default), and i commented "device_port and modem_access" in fsogsmd.conf to disable everything accessed to the modem, after rebooting, the "fuser /dev/ttySAC0" shows none. but when i use "./osmocon -i 13 -m romload -p /dev/ttySAC0 rssi.highram.bin", and "echo 0 > /sys/bus/platform/devices/gta02-pm-gsm.0/power_on && echo 1 > ..." /\ my SHR kernel use this device name for GSM power the osmocon always stalls about at the block 40, for example: ... ... Preparing block 39, block checksum is 0x4c handle_write_block(): 1024 bytes (1024/1024) handle_write_block(): Block 39 finished Received block ack from phone Preparing block 40, block checksum is 0xd5 handle_write_block(): 1024 bytes (1024/1024) handle_write_block(): Block 40 finished and i found that the osmocon start to download codes before my "GSM power reset", very strange, i tried the latest "SHR-core 20120427" and "unstable SHR-lite 20110822", i searched the list log, found "Dave" encounter the same problem, but he solved it after "re-flashing of the phone" i re-flashed the GSM firmware to latest Moko11 (before it's Moko10), but it's the same. BTW, i found that it always shows '1' when "cat /sys/bus/platform/devices/gta02-pm-gsm.0/power_on" even after "echo 0 >/sys/bus/platform/devices/gta02-pm-gsm.0/power_on", what's wrong? anyone can help help me? thanks very much.

bug in local_burst_decode() of burst_ind
by lonelysurfer 12 Jun '12

12 Jun '12

I reused the local_burst_decode function to decrypt the bursts offline. If I filter bi->flags & BI_FLG_SACCH, the sms decryption is working: local_burst_decode(struct l1ctl_burst_ind *bi) ... if (bid == -1) return; /* new */ if (bi->flags & BI_FLG_SACCH) return; ... -- View this message in context: http://baseband-devel.722152.n3.nabble.com/bug-in-local-burst-decode-of-bur… Sent from the baseband-devel mailing list archive at Nabble.com.
