1.3 How to load an image from an ext2 file system in U-boot?
- U-boot doesn't support ext2 write to hard disk, so
- you have to write the image to hard disk under Linux env,
before you load image from ext2 filesystem.
U-boot doesn't support writing to an ext2 file system, so the files must be written by other means (e.g. linux).
