Hi everyone, I am facing a new problem. When i am trying to load layer1 on to mobile phone, getting the following error:   saxena@cosec-ug-vm1-04:/opt/osmocom-bb/src/host/osmocon$ sudo -E ./osmocon -p /dev/ttyUSB0 -m c123xor ../..target/firmware/board/compal_e88/layer1.compalram.bin got 1 bytes from modem, data looks like: 2e  . got 1 bytes from modem, data looks like: c8  . got 1 bytes from modem, data looks like: 1b  . got 4 bytes from modem, data looks like: f6 02 00 41  ...A got 1 bytes from modem, data looks like: 01  . got 1 bytes from modem, data looks like: 40  @ Received PROMPT1 from phone, responding with CMD opening file: No such file or directory Next time when I am trying, it does not show anything and just hang like as: saxena@cosec-ug-vm1-04:/opt/osmocom-bb/src/host/osmocon$ sudo -E ./osmocon -p /dev/ttyUSB0 -m c123xor ../..target/firmware/board/compal_e88/layer1.compalram.bin (no display) Now, the phone is not able to switch on. I pressed red button many times but it doesn't work. can anyone tell me what is wrong in it? With regards Neetesh Saxena...

patches for SIM in the firmware
by Lukas Kuzmiak 16 Dec '13

16 Dec '13

Hello guys, attached is a patch that fixes a few issues regarding SIM reader in Motorola phones (tested on C123), description: if there’s a lot of reading from SIM it happens a FIFO gets full, IMHO the right way is to read until the FIFO is empty (while-loop added) FETCH APDU has to be handled in the same way as GET RESPONSE (added) once REG_SIM_IT_SIM_NATR is triggered it should set the rxDoneFlag to 1 because otherwise there’s trouble recognising NO SIM state on L1 if SIM isn’t present in calypso_sim_powerup() and calypso_sim_reset() should set state to IDLE and put sim_len to 0 because if you do powerdown/powerup the state machine gets messed up unsetting CONFBYPASS should make the CONFSVCCLEV and CONFSRSTLEV irrelevant but it doesn’t, calypso_sim_powerdown() fixed based on calypso spec both calypso_sim_powerup() and calypso_sim_powerup() now return ATR as it should be when you poweron/reset the card some minor debug messages fixed to keep all the messages consistent Patch is apply-able on the current master. Cheers! Lukas

Problem uploading .bin files on Raspberry Pi
by Walter Doerr 09 Dec '13

09 Dec '13

Hello, I am running osmocom-bb on a Ubuntu x86 machine with a Motorola C121. Everything works (as far as I can tell). Now I would like to move the host programs to a Raspberry Pi. So, I did a "make nofirmware" on the Rpi and copied the *.compalram.bin files from the x86 Ubuntu box over to the Rpi. When I use osmocon on the pi to upload the bin file to the phone, the transfer stops after the "finished" line and then, after a while, the phone sends a DOWNLOAD NAK, instead of the usual "DOWNLOAD ACK your code is running now". Has anybody seen this behaviour and knows how to fix it? I have tried two USB/serial adapters (both FTDI based) just in case its a hw problem, but the result is always the same: the upload to the phone works on the Ubuntu/x86 box but not on the pi. Any help is greatly appreciated. Kind Regards, -Walter

[PATCH] COMP128v23 improvements
by ☎ 07 Dec '13

07 Dec '13

Hello. I've got rid of unnecessary cycle and to made difference between v2 and v3 more visible: v2 is basically just v3 with last bits of Kc zeroed. Also - small readability improvements. Also I've added test suite with test vectors from original python implementation. -- best regards, Max, http://fairwaves.ru
