Dear colleagues, I am using the Nordic nrF9151-DK as part of exercise1, lesson 2 of the intermediate Devacademy course. Lesson 2 is about trying and using the various vscode/nRF-Extension Pack debugger features.
Build configuration is set as follows:
SDK: Zephyr v4.1.99
Toolchain: nRF Connect SDK Toolchain v3.0.2
Board target: nrf9151dk/nrf9151/ns
Optimization level: Optimize for debugging (-Og)
After the build files are generated, it looks like this:
After selecting "debug", which should burn the build on the board and begin debugging it, I get the following error message:
Just as a side note, this appears to be a problem with the debugger. I have not had problems flashing code to this board.
Here is my nrf-connect-support-20250610154243.jsonc file:
