Hello Marka,

What is the status of these two threads? Were you able to resolve them? If you find the route cause, please describe it and mark the threads as "Resolved".

As per your current kernel crash. Can you update to the latest Processor SDK since I found that work related to this "Unhandled fault: synchronous external abort (0x210)" message. Setup and calculate the cma size as per this guide and depending how much memory you have on your board try to boot with 256M and 512M cmem sizes and re-run the test. Also does your test application saves any logs on the board? You can get out of storage space after a few weeks running a test program which produces a lot of logs.

Best regards,
Kemal
