Hi

When i implement the imx8mq-evk with android 11.0.0_2.0.0, i found a question, the debug message show as the below

[ 3.726261] EXT4-fs (mmcblk0p8): VFS: Can't find ext4 filesystem

You boot up from emmc or sd card? Are you using demo images?

Dear

it's booting up from the emmc, and i did some modified in the dts. After trace the code, i found the function " is_ext4_superblock_valid" and  "es->s_magic != EXT4_SUPER_MAGIC" will return false.  

attach the debug message

Thanks

Could you tell us what have you modified? If you are using the demo images I can test on my side. If you change the code, you'd better tell us the changes.

Hi

i add the vmmc-supply to avoid the error message in the dts. and the other is the audio codec, usb setting and remove useless setting, and now i found, the "is_ext4_superblock_valid" not always return false, it sometimes will be true, and system run the e2fsck command

pls help to check the dts and debug message

Thanks
