Hi Could you please do reply-all and keep all addresses when replying to a mail? I don't read all mail from the list so it's easy to miss a followup.

Did you define CONFIG_SKIP_RELOCATE_UBOOT? If so, that may be the problem (although I'm not 100% sure) if TEXT_BASE is not 0x81000000 (in your board config.mk). For most i.MX31 boards TEXT_BASE is 0x87f00000. /Magnus _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
