U-Boot ext4 warning
From embeddedTS Manuals
Note: | The ext4 filesystem can also be used but it may require options. Before e2fsprogs 1.43 the default mkfs.ext4 option is safe, but with 1.43 and on the options "-O ^64bit,^metadata_csum" must be used. U-boot does not support the 64bit addressing added as the default. |
