The size of initrd.boot is about 8.5M, then

dd if=3Dinitrd.boot of=3D/dev/mtd2, = cause

MTD do_write_buffer(): software = timeout

dd: /dev/mtd2: Input/output = error

When I change the size of initrd.boot to about = 2M, it’s OK. =

But this 8.5M file can transit by U-boot.

Why ?? Is kernel issue or MTD utility issue = ?

Thanks,

Johnson Cheng
