Unable to program board

amanb

I'm seeing an issue when trying to program the nRF54H20 board. I have python 3.10.9 installed. Does nrfutil specifically need python 3.9? Any support with this would be appreciated

    Hi Jennifer,

    I am able to build it using this configuration as well. However, I am seeing an issue when trying to program the board - it is failing. Even though VS claims a successful program, upon looking at the terminal, I see the error that I attached to this ticket regarding the nrfutil module use of python39.dll.

    Do you see this issue as well or are you able to program the board with the built firmware?

    Thanks,

    Aman

    Hello Aman,

    I just checked and I do not get that error, it flashes for me. I have python 3.11.9 on my machine. I went ahead and also opened an nRF Connect terminal in VS Code and issued the flash command from within my build directory without issue (as well as queried my python version), see attached.

    Are you not able to capture all of your terminal output and copy it to a text file?

    Thank you,

    Hello Aman,

    Sorry for the delayed response. We were in Norway last week for training and I now know exactly how to solve the issue you are having. Please let me know if you are still stuck after trying the following:

    In VS Code, open an nRF Connect terminal and issue the following command:

    pip install nrf-regtool==5.5.1

    Thank you,
    Jennifer Gibbs
