Description Sébastien Szymanski 2017-03-14 14:08:25 UTC

The ext4 image generated by Buildroot can make U-Boot crash once you wrote the image and then try to write a file into it. Notice this is hardware independent as it is reproducible on the U-Boot sandbox. See [1] for more details and the steps to reproduce it.
U-Boot works fine if the ext4 image is generated with mkfs.ext4
(Hence my patch to use mkfs.ext4 instead of genextfs [2])

Comment 1 Thomas Petazzoni 2017-07-19 20:27:33 UTC

This is fixed now that we use mkfs.ext4, since commit https://git.buildroot.org/buildroot/commit/fs/ext2?id=67aaa90d3bbe6ad5b5ffa9e66cdb0a1928448eb9.

Thanks!
