No SIM on GTA02
by radiant radiant 25 Aug '11

25 Aug '11

Hi folks. Running layer1 (no TX) on GTA02 with host applications compiled for GTA02 also. Layer1 seems not able to communicate with SIM card, and so no IMSI etc. Mobile enters in "emergency calls only" mode. Simtest firmware also fails. SIM and phone hardware is checked working with fsogsmd. I cannot find any configure switch to disable/enable SIM, and it has no sense on simtest firmware anyway. Has anything to do with this note on sim.h and the fact that on GTA02 you should cycle the baseband power after osmocon start for romloader to begin? /* Known Bugs: 1.) After powering down the simcard communication stops working */ logs: mobile over layer1 (no TX): ----- <000f> sim.c:1206 init SIM client <0006> gsm48_cc.c:63 init Call Control <0001> gsm48_rr.c:5100 init Radio Ressource process <0005> gsm48_mm.c:1312 init Mobility Management process <0005> gsm48_mm.c:1035 Selecting PLMN SEARCH state, because no SIM. <0002> gsm322.c:5023 init PLMN process <0003> gsm322.c:5024 init Cell Selection process <0003> gsm322.c:5081 Read stored BA list (mcc=XXX mnc=XX $COUNTRY, $NETWORK) <0003> gsm322.c:5081 Read stored BA list (mcc=XXX mnc=XX $COUNTRY, $NETWORK) <0003> gsm322.c:5081 Read stored BA list (mcc=XXX mnc=XX $COUNTRY, $NETWORK) *** Warning: Mobile '1' has default IMEI: 000000000000000 This could relate your identitiy to other users with default IMEI. *** Mobile '1' initialized, please start phone now! <0002> gsm322.c:3804 (ms 1) Event 'EVENT_SWITCH_ON' for automatic PLMN selection in state 'A0 null' <000e> gsm322.c:1356 SIM is removed <0002> gsm322.c:1357 SIM is removed <0002> gsm322.c:800 new state 'A0 null' -> 'A6 no SIM inserted' ----------------- simtest firmware : ----------------SIMTEST----8<----------------- Initializing driver: Power up simcard: (0 bytes) Reset simcard: (0 bytes) 79 f0 ce db f3 cd 8e 7a 10 a1 6c 3a 61 6f 8f (15 bytes) Test Phase 1: Testing bare sim commands... * Testing SELECT: Selecting MF ==> Status word: ffff * Testing SELECT: Selecting DF_GSM ==> Status word: ffff * Testing SELECT: Selecting EF_IMSI ==> Status word: ffff * Testing STATUS: ==> Status word: ffff * Testing READ BINARY: ==> Status word: ffff Data: db 0 0 0 0 0 0 0 0 (9 bytes) ------------END SIMTEST----8<----------------- On the other hand, on GTA02 osmocon or romloader doesn't start if battery is not attached.

Re: GSM-850

Hello Sylvain, On Mon, 22 Aug 2011 16:35:04 +0200, "Sylvain Munaut" <246tnt(a)gmail.com> wrote: > > I think some phones just have swapped IQ lines for easier routing .... This wouldn't explain why the C122 GSM-850/1900 needs the "I/Q-swap" for GSM-850 TX only. And if I remember, Harald tried it with a GSM-900/1800 phone on GSM-850 (of course there are filter issues in this case) and it required the "I/Q-swap" again for GSM-850 only.

GSM-850
by Dieter Spaar 22 Aug '11

22 Aug '11

Hello, I don't know if anyone has already successfully used OsmocomBB with GSM-850. It seems that although receiving on GSM-850 works, there are issues when transmitting. The phone produces a signal on the correct ARFCN, however the BTS can't make use of it. The problem seems to be "I/Q-swap", something which can be turned on in the DSP independently for receiving and transmitting. So far it seems that this was not needed, at least for receiving and also for tranmitting when using GSM-900/1800/1900. However for GSM-850 it seems to be essential for transmitting. It is not clear if different phones behave differently, this might be the case. Also it might be the case that some phones require to turn on "I/Q-swap" when receiving on certain bands. Considering all those uncertainties of "I/Q-swap" the appended patch should be considered as a suggestion, it might be neccessary to make it dependend on the phone and also to introduce a similar function for receiving. At least with the patch a C122 GSM-850/1900 phone now works on GSM-850 too. Thank you very much to Harald who remembered that there was this "I/Q-swap" thing for the DSP.

Preparing mobile for osmocombb
by Pavel Baturko 22 Aug '11

22 Aug '11

Hi All, Do I need to prepare my phone for uploading the firmware with osmocon tool? I tried to load firmware on Motorola C118 and C115 with Prolific PL2303 USB to serial adaptor (computer->usb->com->3.5mm jack->2.5mm jack->phone) and when I briefly press the power-on button of my phone as it's stated in manual - I got no response from phone. Seems it does nothing. Cable seems to be working, because it detect contact with phone's 2.5mm socket when I plug it into phone as - 'got 1 bytes from modem, data looks like: 00 .'. Thanks, Pavel

libosmocore/osmocombb build error
by Job 21 Aug '11

21 Aug '11

Hi, When building osmocombb with an updated src/shared/libosmocore (0.3.6) the build fails due to make attempting to build utils/osmo-arfcn.c for build-target which does not have stdio. I have no patch as I was not sure what the preferred way to solve it is. Maybe a --disable-utils like for tests? Best regards, Job make[3]: Entering directory `osmocom-bb/src/shared/libosmocore/build-target/utils' CC osmo-arfcn.o ../../utils/osmo-arfcn.c: In function 'arfcn2freq': ../../utils/osmo-arfcn.c:43: warning: incompatible implicit declaration of built-in function 'fprintf' ../../utils/osmo-arfcn.c:43: error: 'stderr' undeclared (first use in this function)

Enabling PCS bands on the C139 (originally on PCS)
by Lokkju Brennr 20 Aug '11

20 Aug '11

I keep forgetting how to make this work, and it just came up in IRC again, so I thought I would archive the answer to the list: per tnt: in src/target/firmware/board/compal/rffe_dualband.c , the rffe_get_rx_ports might need to have PCS1900 instead of DCS1800 Some phones have different RF wiring and we can't autodetect it ... (the thing is that unless you try manually or look at the PCB you can't really tell ... some PCS phones have it wired to the DCS input ...)
