Thanks for the information. My problem is that "md 0xFFFFE000" and any other read command up to this address works fine. Its just when I try to read @ 0xFFFF F000 I see this problem.
This problem with accessing the last 4k after NAND booting looks like a problem with either cache or TLB setup to me. Please keep in mind, that while booting via NAND the IPL (initial program loader) included in the PPC loads exactly 4k of code into the i-cache at the last 4k. So this is exactly your faulting location.
Note: I have not seen such issues with the NAND booting 4xx board I tested on so far.
