Hello Enyi,
Please refer to the datasheet:
Do you see how AM623x parts can have 4 A53 cores, or 2 cores, or 1 core depending on which AM623x part you are using?
I need you to figure out EXACTLY which part number you are using. If you are not using AM6234, then you need to disable the nonexistent A53 cores in the Linux device tree. Refer to the link in my previous thread.
Regards,
Nick
