Hi,
I am using I.MX6ULL + NAND Flash.
What causes "UBIFS error: ubifs_check_node: bad CRC" and how to fix it?
The following is the boot log.

=======================================================
I wonder if the cause of this problem is H/W or S/W.
I would appreciate it if you could answer my question.
