 Trying some ext4ls shows there is some problem accessing the filesystem.

 Not sure if this should be attributed to the ext driver or to the mmc
 driver or something else entirely.

This works for me.

If a fix is too difficult to roll out immediately at least an error
message when trying
to mount filesystem with unsupported features would be nice.

Thanks

it's csum/64bit, disable it:

mkfs.ext4 -O ^metadata_csum,^64bit

Reformatting without flex_bg does not seem to have any effect.

However, ls seems to give some random stuff for directories other than
/ so some similar remapping feature could cause this.

[U-Boot] Problem loading boot script from ext4 mmc on sunxi H3

2016-06-29 Thread Michal Suchanek 
Hello,

I tried loading system with recent u-boot but it does not work.

Trying some ext4ls shows there is some problem accessing the filesystem.

Not sure if this should be attributed to the ext driver or to the mmc
driver or something else entirely.

Does this work for anybody? Any debug option to turn on?

Thanks

Michal
