Re: Non Standard Baud Rates?
by MATTHEW EVANS 04 Feb '11

*bump* Anyone have any thoughts / advice on this? Many Thanks, Matt. ----- Original Message ---- From: MATTHEW EVANS <mattjevans(a)btinternet.com> To: baseband-devel(a)lists.osmocom.org Sent: Friday, 21 January, 2011 21:08:36 Subject: Non Standard Baud Rates? 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.

Make sure of the following: 1. Edit ~/.bashrc and put export PATH=$PATH:<YOURPATH>/install/bin , where "yourpath" is your full path to where arm-elf-gcc is located 2. restart your computer (sometimes it helps) 3. run the "make" under the same user that has the above path (no sudo make !!!)

AGCH question.
by Leonardo Nve 03 Feb '11

03 Feb '11

Hi everyone. I´m coding a fuzzer with osmocombb API, I expect send you something good in a mounth or two (It depends how much work i have). I have two questions. First, I triying a simple SMS handler, to send and receive. With wireshark I don´t see RACH request, I suppose it is because the DSP inside the phone manage it, am I wrong? About this, I don´t have knowledge about electronics, so I don´t want touch, any filter. So I need to see the RACH of the same phone were osmo is running, not another. The second question is about SI AGCH response, I didn´t find the algorithm to know which SDCCH channel gives the BTS to the MS to send/recv LAPDm bursts. --- Leonardo Nve leonardo.nve(a)gmail.com ---

[PATCH] Two minor patches for the firmware
by Holger Freyther 02 Feb '11

02 Feb '11

Hi laf0rge, I was building the firmware with a GCC 4.5.2 created by Steve-m's script and had to include limits.h for UINT_MAX. While reading the code I stumbled across a typo... I think the patches can be picked to master as well. holger

SIMtrace issues
by tsaitgaist 02 Feb '11

02 Feb '11

hi, I'll be listing some issues I found in SIMtrace. This is to warn future users. I don't have time now, but I intend to work on this project in 1 or 2 weeks and correct these bugs. 1. when starting host program simtrace, the firmware will first return ATR. This is an error if simtrace is started after the card has been reseted. The program should use the state of the reset and vcc lines to know the state. 2. when using a usb hub, having a lot of USB traffic, or poor USB signal quality (I don't know exactly), bulk read timeouts can occur in host program simtrace/at91sam7/host/main.c line 230: rc = usb_bulk_read(udev, SIMTRACE_IN_EP, buf, sizeof(buf), 100000); rc is -110 (REQUEST_TIMEOUT). I increased the timeout (100000) so to have less errors (but they still occur), and I ignore this error instead of exiting (tracing still works). 3. it seems simtrace can loose track of the I/O stream after some traffic. see pcsc_apdu.log to see the original, and simtrace_apdu.log for the captured traffic. in the end, simtrace misses: APDU: A0 C0 00 00 0F and does a wrong following APDU parsing The problem occurs when using a OmniKey CardMan 5321 and Alcor Micro AU9520. Thus the reader should not be the origin. Also, if only the command where the error occurs is sent, no bytes are skipped. But another error occurs (see next bug) 4. when executing only the last commands, then it is wrongly interpreted (as ATR), but no bytes are skipped ATR (12): 3b 0a 41 00 3f 43 00 01 50 29 01 02 ATR (66): a0 a4 00 00 02 a4 7f 20 9f 17 a0 a4 00 00 02 a4 6f ad 9f 0f a0 c0 00 00 0f c0 00 00 00 03 6f ad 04 00 04 f0 44 01 02 00 00 90 00 a0 b0 00 00 03 b0 00 00 00 90 00 3b 0a 41 00 3f 43 00 01 50 29 01 02 I already wrote a SIM traffic parser for the PC before simtrace appeared. I used a logic analyzer to record the traffic. I will integrate the ATR and APDU parsing/checking into the simtrace firmware. Wrong recorded traffic will be discarded instead of affecting the rest of the parsing. thanks, kevin

cell_log and debug
by Dario Lombardo 01 Feb '11

01 Feb '11

Shame on me when I'm not able to print debug messages from cell_log :) but... cell_log -d DRR,3 doesn't give me any additional output. I would like to see the line LOGP(DRR, LOGL_INFO, "IMMEDIATE ASSIGNMENT:\n"); from cell_log.c. Can anybody help me?

http mirror for osmocom-bb.git ?
by Sébastien Lorquet 01 Feb '11

Hi, I know we have a http git mirror for openbsc. Do we have the same for osmocom-bb.git? the git tcp port is censored where I'm connected from. Sorry if I misread the list archive :( Sebastien
