Yes, this is exactly what I was seeing. > Reason: the chip presents CFI data correctly (from the flash point of view) > in 16 bit mode (flash A0 connected to CPU A1).

Anyone is welcome to add that special handling for 16 bit > flash connected in 8 bit mode to the general CFI driver :) Thanks a lot! I'll take a look, and see if I can understand it. :-) Rogan _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
