I realize this isn't a BDI3000 mailing list but I was hoping to get some input on my problem. I am trying to program u-boot onto the flash (S29GL512N) of a ppc440gx target using a BDI3000 but I am getting some weird behavior.
With my current BDI3000 (firmware v1.18) configuration (using SDRAM as the BDI workspace) the first program attempt always fails. Successive attempts after the failed one will work.

One interesting thing is when I dump the failed programming attempt and diff it's contents versus my u-boot image it's only the first 512 bytes that are incorrect. Within the 512 bytes I can partially see the contents of the image with some of the data corrupted.
Another characteristic of my problem is I can program the flash if I allow u-boot to configure the board.
This sounds like a memory configuration in your BDI script for me. I suggest you check again the SDRAM controller parameters against the ones configured in U-Boot.
Cheers, Stefan
