It is the right place where we can exchange experience on u-boot. > BTW, I just blasted u-boot into the 1st part of the SD > card and prayed: > > sudo dd if=u-boot/u-boot.bin of=$(SD_CARD) bs=512 seek=0 If this is the u-boot you find in the ltib, the command could be correct. It depends how u-boot is built. The MX51 processor reads automatically the SD card starting from address 0x400. At this address, the processor must find the DCD table. In the patches I sent, I follow another approach: u-boot is build independently from the device where you will store the bootloader. You have to generate u-boot.imx (with "make u-boot.imx"), that adds the DCD table and then you must store it at the correct offset. On a SD card, this means with: dd if=u-boot.imx of=$(SD_CARD) bs=512 seek=2 Do you try the patches I sent to the ML ? And which is the version of your processor (TO1, TO2 or TO3) and of the board ?
