Hi rakesh_patel

EXT4-fs (mmcblk3p2): mounting ext3 file system using the ext4 subsystem 

is described for example on

https://unix.stackexchange.com/questions/339449/mounting-ext3-file-system-using-the-ext4-subsystem-w...

If one uses mfg tool one can try to change mkfs.ext3 in ucl2.xml to mkfs.ext4

or follow i.MX Linux User’s Guide​  for creating partition.

Best regards

@igorpadykov :

@igorpadykov :

I have fixed this issue as some kernel configurations and voltage regulator causes the issue in the custom board.

But, I have one query for NXP:

1) mfgtool do ucl2.xml file do ext3 partitions. Is there any reason to choose ext3 as default? Why not ext4?
