Creatng a list of known issues somewhere
by Holger Hans Peter Freyther 24 Jan '11

Hi all, it appears that we all know of some issues but we are not writing them down. Would it make sense to start using the bugtracker for that? Or just a dedicated wiki site?

problems getting Pirelli DP-L10 to work
by Leif Jakob 24 Jan '11

24 Jan '11

Hi, maybe I'm missing something, but when I read that the Pirelli DP-L10 would be supported I tried to get it running: I didn't patch my usb-module, but used: modprobe -v cp210x echo "0489 e003" > /sys/bus/usb-serial/drivers/cp210x/new_id from the steve-m/testing-branch I compiled the firmware and loaded it with ./host/osmocon/osmocon -p /dev/ttyUSB0 -m romload target/firmware/board/pirelli_dpl10/hello_world.highram.bin onto the phone... that worked but I was never able to see any messages after the upload: Received block ack from phone Sending checksum: 0xaa Checksum on phone side matches, let's branch to your code Branching to 0x00820000 Received branch ack, your code is running now! ... there it stayed forever ... I'm pretty sure that the code runs, because I commented in init.c the keyboard lighting code and it didn't light up after upload. I've tried other bins but to no success. Any hint or am it too early playing with that hardware? Greetings Leif

Regarding IMSI detach DoS
by Bogdan Alecu 24 Jan '11

24 Jan '11

Hello, In order for this attack to work it has to be on a GSM network because on 3G there is a higher security mechanism. A way to protect against this, for the opperator, could be to implement 3G over 900Mhz so this way even if the targeted phones are on 2G they will still be protected. Am I right? Regards, Bogdan

serial cable
by Tommy R. 24 Jan '11

24 Jan '11

Hey, I ordered the serial cable coming from dealextreme and it has not arrived yet. I noticed today that the link was taken off the wiki due to it not being at TTL levels. I was wondering if I bought a Nokia serial cable (the ones that have the prolific chips in them) which runs at 3.3v out of the box, could I just connect the tx and rx pins to the cable I had bought and it would possibly work or would that be a bad idea and I should cut my losses and kill the order. -- -Tom

Non Standard Baud Rates?
by MATTHEW EVANS 22 Jan '11

22 Jan '11

Hi, I'm trying to get the burst_ind branch working at the higher speed baud rates. I have a USB to Serial FTDI Cable (FT232R) plus the T191. This setup works fine with the main trunk of osmocombb. When I fire up osmocon, layer1 appears to download to the phone and runs successfully. Osmocon then logs 'Received DOWNLOAD ACK from phone, your code is running now!'. The phone has layer1.bin displayed as usual. However it goes no further and just hangs. Could anyone please give any advice on what to try next? Thanks, Matt.

Why my phone can't attach the network?
by xuchenyu 22 Jan '11

22 Jan '11

Thanks to Tomas and ton, I can run osmocombb on the phone. But the phone can't attach the network, can't make a call, can't recognise the SIM card. I found that this was no BCCH received in wireshark. And when I type some command via telnet localhost, it always output "Command incomplete" Anybody can give me some solution? Thanks! -- View this message in context: http://baseband-devel.722152.n3.nabble.com/Why-my-phone-can-t-attach-the-ne… Sent from the baseband-devel mailing list archive at Nabble.com.

Re:radio is not started
by Bogdan Alecu 22 Jan '11

I guess you have the default configuration: "No Mobile Station defined, creating: MS '1'" After you start "mobile" application, select "enable" and then "write". This will write your configuration to /etc/osmocom/osmocom.cfg After that edit this file and set from no sim to sim reader. Restart the mobile application and it should work.

Motorola usb cable
by Dario Lombardo 21 Jan '11

21 Jan '11

Hello everydoby I have Motorola-branded prolific usb cable. This cable, once inserted in a port, claims to be a 0307 chipset adapter, and Linux kernel doesn't recognize it: not working. Someone told me that Motorola has changed the label in those cables that claim to be 0307, but they are pl2303. Does anyone have one of these cables working? I've tried many ways, including udev, to make it work, but no success. My next step is to recompile the kernel module, but I was wondering if someone has solved it in another way. Bye Dario.

Pirelli DP-L10 support, steve-m/testing branch
by Steve Markgraf 21 Jan '11

21 Jan '11

Hi all, last weekend I have grinded down a DP-L10 pcb and traced the TSPACT wiring of this board. I've added support for this phone, along with a few other changes in my branch steve-m/testing. Changes include: * Add support for Pirelli DP-L10 * Add TX support for the gta0x devices * separate board images for the Compal E86 (Motorola C139/C140) (display/keypad backlight now works by default) If anyone wants to test those changes (especially the freerunner TX support, since I have no freerunner), please feel free to do so. I tested the other changes and didn't find any regressions, so if no one else does, we can merge it to master soon. One thing I noticed during testing: The C139/C140 seem to have a different SYSTEM_INHERENT_GAIN, I compared the RX levels of several C118/C123/C155 with several C139/C140, and the reported rx level was always at around 18-20dBm worse than with the C123. Regards, Steve
