Glad to hear you found a way to work around this. Unfortunately, I'm afraid I don't have a good explanation for this. We use J-link for our boards, but even if there was an issue with the pyocd programming sequence, I don't see how it would lead to this runtime failure. The runtime error suggests that there is a bug in the FW.

Hi Vidar,
Thanks a lot for your reply
I was able to resolve that issue, the issue was that i was erasing the flash using pyocd and flashing the code using west that was causing some issue i don't know what but i switch from this to erasing the flash and flashing the code both with pyocd and now i am not facing it. I don't know what exactly went wrong it would be wonderful if you can explain me what was wrong there

Hello,

I wasn't able to replicate this here with SDK v3.2.1. Can you confirm that this is the build target you are using:
