I am trying to update U-Boot on my MPC8349EA-MDS.
How old was the U-Boot version that you upgraded from?
I am upgrading from 1.1.3, that shipped on the board.
The MPC9349E boot sequence was modified at one point, and so to boot a new kernel you had to also change the HRCW. I forget the details, but here's my notes ...

see the comments on p18.
I am pretty confused by your notes as they relate to my image. For me, I am flashing at fff00000. This is sufficient to brick the board :-D. It seemed like your notes were reflecting a change in the boot address between versions? I tried to use the addresses you mention and 1) fe000000 tells me it is not erased, even after I erase it (?) and 2) fe700000 seems to have no effect. I thought those were the u-boot locations for the mpc8349ITX (?).
Just to be clear, I am not even at the point of booting the kernel, just trying to get to the u-boot prompt of a new u-boot.
I really appreciate the help! Unfortunately, I am just more confused at the moment. Thank you, Michael
