Aegean Chou aegean2000 at 21cn.comHi 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.
