Yes i am where that there is no NAND controller so did that already and i see stuff happing on my scope. I thought that i was missing something for this flash chip.
I am attaching my nand controllor code could any body tell me if i am missing something for the 405EP i am new to the 405EP processor... But i worked on did processors that i had nand setup and it was a lot lets work.
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.
