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