Understood. Thanks for the information.

Please let me know when a fix is available.

Hi, I had a colleague test one more time with linux, and there does seem to be an issue with nrfutil. You should be able to collect modem traces through cellular monitor while waiting for a fix.

Kind regards,
Øyvind

Currently only 7.11.0 version is available for download for Linux (Running Debian)

https://docs.nordicsemi.com/bundle/nrfutil/page/guides/installing.html

https://www.nordicsemi.com/Products/Development-tools/nRF-Util

The trace utility version is the same.

Where are the debug logs stored? I'm not getting them in stdout.

I used the command you provided. i was able to run it for a while, collecting 18k of data. Have not heard of this issue before, so will need to investigate more.

Here is my version

oysa@NordicTechSupportM2 ~ % nrfutil --version 
nrfutil 7.13.0 (8289424 2024-07-01)

oysa@NordicTechSupportM2 ~ % nrfutil trace --version

Could you try running with --log-level debug i.e.

nrfutil trace lte --log-level debug --input-serialport /dev/ttyACM1 --output-pcapng wireshark-$(date +%s).pcapng

I recently installed the trace and device utilities.

nrfutil-trace is already the newest version (2.11.0)
nrfutil-device is already the newest version (2.5.4)
[00:00:01] ###### 100% [Upgrade packages] Upgrade packages

I don't think I've updated nrfutil itself. Is it was of the Nordic command line tools package?

For some additional context, it doesn't crash immediately. Here's an example:

I ran the command in a while loop. Whenever it crashed, it would immediately create a new trace. You can look up the file creation times above to understand the frequency a bit better.

Could you post how you ran the trace utility? I can try running it the same way.

Hello,

I've tested on my macbook and another linux device, and was not able reproduce. Have you updated you nrfutil?

KInd regards,
Øyvind
