All 8-bit mode checks assume the QRY bytes are at addresses 0x10, 0x11, 0x12 etc. So they fail too, since a mixed-mode chip outputs a word-mode QRY always, at addresses 0xx20, 0x22, 0x24 etc. Amicalement, -- Albert. _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
