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

Hello Aman,

This was done through the nRF Connect extension in VS Code, correct? When you installed the Toolchain and SDK, did you use VS Code or nRF Connect for Desktop? Also, did you install locally or globally?

Thank you,

Hi Jennifer,

That's right, I did it through the extension in VS code, and I installed the toolchain and SDK through there as well. VS code is globally installed

Thanks,

Aman

Hello Aman,

Something isn't right, nrfutil is the command line tool. I don't believe you have things installed correctly. If you go to this link: Exercise 1 - Nordic Developer Academy (nordicsemi.com) it has both a YouTube video and written instructions on how to properly install nRF Connect for VS Code Extension, Toolchain, and SDK within VS Code. Could you possibly uninstall what you've got and follow these instructions to see if that will fix your installation? 

Thank you,

Jennifer Gibbs

Hello Aman,

Did you have luck after reviewing the Installation video/walkthrough on the Developer Academy? 

Thank you,

Hi Jennifer,

The walkthrough in the developer academy is identical to how I installed all my tools. I am running the flash command through visual studio and it is selecting nrfutil as the runner for the task when I attempt to flash the NRF54H20. This is different than what I see on the L15 (it selects nrfjprog). It seems to me like there could be a bug in the SDK with regards to the NRF54H20, since the tools work fine for the L15 as well as the NRF52840. Does this same process work for you? Does it select nrfutil or nrfjrpog? Which one is correct for the H20?

Thanks,

Aman
