Hello,
Our customer found out this problem when they tried to boot the Beaglebone Black. We have tested again with our BBB using Linux RT SDK ti-processor-sdk-linux-rt-am335x-evm-07.03.00.005 and the issue also happened. After 20 times of rebooting, the error occurred once. Following is the trace log:
