>From looking at the code, I wonder *how* you did implement the external logic on your board. I would have thought you connected some of the NAND control pins to 405EP GPIO's. But this doesn't seem to be the case. You are accessing the CMD/ALE singals at different addresses. So what exactly is you external NAND controller logic? If not, I suggest you take a look at: board/esd/common/esd405ep_nand.c This is an 405EP NAND implementation with external logic and signals attached to GPIO's.
