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?
Regards,
Harald

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

I've followed these instructions:
https://osmocom.org/projects/simtrace2/wiki
- have my user id plugdev group (logged out to verify),
- verified that udevs are right and service has been restarted.
https://git.osmocom.org/simtrace2/plain/host/contrib/99-simtrace2.rules
- here is the list of libusb:
libgusb2:amd640.3.5-1build1

Also I've tried to flash the latest firmware like in this document,
with the "simtrace-trace-dfu-latest.bin" from
2022-Jan-25 07:52:30
https://osmocom.org/projects/simtrace2/wiki/Flashing#DFU
Please advise where is the problem
Thanks

I would be very grateful for help getting my SimTrace2 going under Debian 10 please. I have followed the instructions for getting the repository onto my system but am unsure how to install trace or the Wireshark plugin?
Kind regards,

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?
Regards,
James

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

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

And here the debug log:

Can anyone point me to a resource for computing parameters with a valid MAC?
