OsmoDevCon 2022 ?
by Harald Welte 11 Mar '22

11 Mar '22

Dear fellow Osmocom developers, as you all know, we've sadly had to skip OsmoDevCon 2020 and 2021, trying to compensate it at least to some extent with our OsmoDevCall every two weeks. The COVID-19 pandemic is far from over, and we don't know what the upcoming winter season will bring. Nevertheless, I think it would be a good idea to start a discussion of whether we should plan for an OsmoDevCon in 2022. I personally would say let's plan for the usual late April 2022 time frame, and if the pandemic situation deteriorates, we can still cancel it with something like one month lead time. I would also personally suggest to limit attendance to people who are fully vaccinated, and in addition do a self-test for all participants every morning. In terms of venue, we might also consider to move to a venue that allows better ventilation. Irrespective of the above we can also bring the air filters from the sysmocom office. So with that as an input statement, I would like to hear your opinion on the above proposals. Who would want to attend? Any complaints against the "vaccinated only plus daily self-tests in the morning" approach?

I have followed the procedure on https://osmocom.org/projects/cellular-infrastructure/wiki/Latest_Builds <https://osmocom.org/projects/cellular-infrastructure/wiki/Latest_Builds> for adding the repository to my system but con’t find any instructions for how to get the binaries or the Wireshark plugin to use the SimTrace2 hardware. Please can you point me to the right page with full installation instructions? Thanks, Simon

Hello, I've just received SimTrace2, LED green and red are flashing. Even phone is able to connect to telecom network. However, connecting to USB on Ubuntu 21.10 does not work (also tried with Ubuntu 20.04.3 LTS). No /dev/ttyUSB*, or /dev/ttyACM* appears. Here are dmesg: [ 4513.939503] usb 1-4.1: USB disconnect, device number 26 [ 4514.931801] usb 1-4.1: new full-speed USB device number 27 using xhci_hcd [ 4515.036480] usb 1-4.1: New USB device found, idVendor=1d50, idProduct=60e3, bcdDevice= 0.02 [ 4515.036494] usb 1-4.1: New USB device strings: Mfr=1, Product=2, SerialNumber=11 [ 4515.036501] usb 1-4.1: Product: SIMtrace 2 [ 4515.036505] usb 1-4.1: Manufacturer: sysmocom - s.f.m.c.

Simtrace2-tool communications issue
by James Tavares 11 Jan '22

11 Jan '22

Hello, I am having a communications issue between the simtrace2 firmware & simtrace2-tool. It appears that only the first invocation of simtrace2-tool after reset of the Atmel processor works. Subsequent invocations of simtrace2-tool fail (to be specific, the simtrace2 firmware never calls usb_refill_from_host() nor dispatch_received_msg() for the lost message, according to additional debugging I added). We have confirmed this behavior on a stock simtrace2 board and stock simtrace2 firmware. As an experiment: With the Atmel processor in this state, I modified simtrace2-tool to send two commands back to back: a dummy message, followed by the real message. When I do this, the first dummy message is dropped, as described above, but the second is executed successfully! For some reason, you cannot get it to work by simply invoking simtrace2-tool twice at the shell— critically, you have to send both messages without closing and re-opening libusb in-between. The root cause is probably some kind of message framing or USB stack receive processing race condition in the simtrace2 firmware, relative to when the USB port is opened on the 2nd and subsequent times. Or, maybe some kind of race condition with usb_refill_from_host() that primes the receiver for another packet? Honestly, I’m not sure. Do you have any suggestions? Are you aware of this issue?

lists.osmocom.org migrated to mailman3
by Harald Welte 04 Jan '22

04 Jan '22

Dear Osmocom community, today our mailing list server lists.osmocom.org has finally been migrated from mailman2-on-freebsd to mailman3-on-linux. This also included a variety of changes to DNS. I'll spare you the details, but everything _should_ be up and running now. * The List-Id headers should not have changed. * all list subscriptions + user accounts have been converted. * old 'static html' archives are still available (read only) at URLs like https://lists.osmocom.org/pipermail/baseband-devel/ * old List URLs like https://lists.osmocom.org/mailman/listinfo/baseband-devel are redirected to their respective modern counterparts In case you notice any mailing list related problem, please don't hesitate to contact me. Happy hacking, Harald -- - Harald Welte <laforge(a)osmocom.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

The first time it even sends a C-APDU, but no SW is returned. Also the data stream (ATR and APDU) look correct, so it does no seem to be a speed issue. I only had the card for 5 minutes and did not try to debug it more (check it the PPS fails, or something afterwards) or use an oscilloscope. But maybe someone might have an idea. Here the SIMtrace log: Entering main loop ATR APDU: 3b 9f 95 80 1f c7 80 31 a0 73 be 21 13 67 d0 02 04 09 01 00 00 05 PPS(Fi=9/Di=5) ATR APDU: 3b 9f 95 80 1f c7 80 31 a0 73 be 21 13 67 d0 02 04 09 01 00 00 05 PPS(Fi=9/Di=5) APDU: 00 a4 00 0c 02 fc 00 ATR APDU: 3b 9f 95 80 1f c7 80 31 a0 73 be 21 13 67 d0 02 04 09 01 00 00 05 PPS(Fi=9/Di=5) ATR APDU: 3b 9f 95 80 1f c7 80 31 a0 73 be 21 13 67 d0 02 04 09 01 00 00 05 And here the debug log: main(76): entering main (idle) loop VCC_PHONE off VCC_PHONE on RST computed Fi(1) Di(1) ratio: 372 found Fi=9 Di=5 computed Fi(9) Di(5) ratio: 32 nRST VCC_PHONE off VCC_PHONE on RST computed Fi(1) Di(1) ratio: 372 found Fi=9 Di=5 computed Fi(9) Di(5) ratio: 32 nRST VCC_PHONE off VCC_PHONE on RST computed Fi(1) Di(1) ratio: 372 found Fi=9 Di=5 computed Fi(9) Di(5) ratio: 32 nRST VCC_PHONE off VCC_PHONE on RST computed Fi(1) Di(1) ratio: 372 found Fi=9 Di=5 computed Fi(9) Di(5) ratio: 32 nRST VCC_PHONE off thank, kevin
