Does anyone have this same issue?
DM355 and DM365 has similar issues as the RBL expects a different OOB/ECC
layout to Linux.
Slightly off-topic, but in the 355/365 (etc) case it's possible to modify
the Linux driver so it uses the RBL ECC layout. For us, it seemed the
easiest thing to do, as having different ECC layouts in different parts
of the flash proved to be a pain. If you need different ECC algorithms in
different parts of the flash this wouldn't work of course.
