Tool/software: Linux
Hi,
I use Processor SDK Linux AM57x 03_03_00_04.
When I try Linux SD boot with AM572x EVM(TMDSEVM572x), boot failure happens once a hundred times approximately.
The below is the boot log when failed.
---------- failed ----------

I think the cause of failure is miss read from SD card. Is my understanding right? If the data can't be read from SD card, is it timing issue?
Please let me know how to fix this issue.
I appreciate your quick reply.
Best regards,
Michi
