Dear, I found this message on the list :
lists.denx.de/pipermail/u-boot/2012-March/120801.html I m able to start u-boot from Redboot but I don't know how to download the u-boot-nand.bin from my tftp with u-boot and then copy it to the flash to erase redboot. I m also using the KA-RO TX25 board. I have some ideas about how to do it but I m not sure and I don't have any J-TAG board in case something go wrong. Thanks Best Regards Crausaz Romain _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
