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.

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.
Best Regards
Aegean
