Well i guess my computer is the one out of spec i guess.  I'm going to be updating to ubuntu 26.04.  So i'll close this for now and if it continues then i'll repost this.

Hi @Brenden_PLUS

I can read OTPs just fine on my side with the DK board (Also it seems we have the same chip rev ID).

Can you share a higher verbosity log with both versions of the tool ? v2.21 vs v2.22 ?

Thanks in advance,

Aziz

    Didn't see that verbose thing!  Also I'm on linux, but it seemed to be a problem on windows as well.

    • Ubuntu 24.04.3 LTS

     

    Logs are attached.  

    Version 2.22

      Hi @Brenden_PLUS

      Sorry for the late reply but I couldn't reproduce the issue on my side even on ubuntu.

      Did you figure out anything else, could you share any further details that might help us reproduce the issue?
