Hi!
With the release of NCS 3.0.1, the required SEGGER JLink version to v8.18. pynrfjrprog is bundled with SEGGER JLink v7.94. From your website, it seems nrfjprog, being part of the nordic command line tools, has been replaced by nrfutil (which seems to be mainly for nrf5-sdk? https://www.nordicsemi.com/Products/Development-tools/nRF-Util ).
I really like pynrfjprog. Is there a replacement python library based on nrfutil which I can use with NCS 3.0.1?
Best regards,
Fridtjof
