STM32CubeProgrammer can't read OTP bits STM32N6

Brenden_PLUS · ‎2026-04-15

I can't seem to read the OTP bits on the stm32N6 with any of my boards with 2.22 of the stm32CubeProgrammer.

But i can on version

2.21

Everything else works fine with the chip.

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

Version 2.21

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?
