Hi Tormod, It turns out that there is a possible race condition or corruption which is overwriting one of the dev structures while traversing the device list. This causes the search loop of device ID list, to terminate early when checking the value of stm->dev->id, making the code think the MCU device ID is not found. It's a bit tricky to track this down, as issue occurs randomly. I narrowed it down after several attempts to capture debug details - with a watchpoint enabled for it. as shown below,...
