Hi all,
I have a board based on the MPC8360E-RDK, and im trying to make NAND at local bus works with UPM. I put the scope to see what was going wrong and I got this:

The ascii art attempt failed. ;-)

One detail, im using u-boot-1.1.4 and i got the codes for UPM and NAND from u-boot-1.3.4-rc1.
Since the boards are pretty the same, I guess you can just compile the u-boot-1.3.3 (please try release instead of -rc, to be sure), and see if NAND will work. Maybe it will need really small code modifications for your board though.
Otherwise it is hard to say where is problem is (maybe the problem in the 1.1.4 nand core code, not in UPM setup?).
Also, you didn't mention what kind of chip the board is using.
Thanks,
