Unable to program board

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

  • Hello Aman,

    Which version of the nRF54H20 PDK are you using? You can just take a picture of the white sticker on the board for me if you want. Also, what version of the SDK and toolchain are you using again? I believe the only version of the SDK that is compatible with the nRF54H20 is v2.7.99-cs1 and that is only compatible with PCA10175 v0.8.0. I believe this may be the issue you are running into. 

    Thank you,

  • Hi Jennifer,

    I've attached a picture of the dev-kit below, it seems to be the correct one. 

    I've been using version 2.7.0 of the SDK - that would explain the issues I'm seeing. Is there an updated version of the toolchain? I only seem to see versions up to 2.7.0, even after updating the SDK to 2.7.99-cs1, and when I try to build with this combo of SDK 2.7.99-cs1 and toolchain 2.7.0, I get the below error, presumably because the versions are mismatched.

  • Hello Aman,

    Yes, use toolchain v2.7.0 with SDK v2.7.99-cs1. You have the correct board so you should just need to update your SDK version. Let me know if you have any issues with that.

    Thank you,

    Jennifer Gibbs
