Other Parts Discussed in Thread: DRA752
1、We produced 320 core boards this time, and found that 11 failed to be burned. The printed information that cannot be burned is the same as the attachment；
The error message is shown in the attached table
The following part of the LOG is missing from the normal board：
EXT4-fs (mmcblk1p2): recovery complete
EXT4-fs (mmcblk1p2): mounted filesystem with ordered data mode. Opts: (null)
VFS: Mounted root (ext4 filesystem) on device 179:2.
devtmpfs: mounted
Freeing unused kernel memory: 372K (c087a000 - c08d7000)
INIT: version 2.88 booting
2、There are 3 pieces of the first burn OK, burn again will not burn on, the printing error is as follows;
two ERRON log：

Where are the possible causes of the above problems, and where are they checked from the software and hardware？
