Hi, I am trying to update some (for the most part very ugly) code from a source tree based on u-boot 1.1.6 which I have been given to a more up to date version (I am trying to get 2008.10 to work for now, and I am hoping that when it does, keeping in line with the main tree will be a bit easier).

I have managed to get 2008.10 to run, but I simply get this on the serial output: U-Boot 2008.10 (Jan 9 2009 - 10:57:15)

DRAM: 64 MB manufacture ID = 191lx device ID = 9051lx Flash: 4 MB NAND: 0 MiB

And then, it reboots and does the same thing again.

Clearly the NAND driver isn't working properly, so does anybody have any ideas about specific things I should check? I have included the source below in case anybody can spot something obviously wrong with it.

Many thanks, Adan
