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.
