I Flash the files in the SD (e.g. /dev/mmcblk0) card with: sudo dd if=SPL of=/dev/mmcblk0 bs=1K seek=1 sudo dd if=u-boot.img of=/dev/mmcblk0 bs=1K seek=69 But I can't find the folder /dev/mmcblk0. Can anyone help me? Sorry my english is not good.
The name dev/mmcblk0 is an example, you have to use the real name. You have to find the real name of the SD on the system were you have compiled and/or stored the u-boot on. From the documentation:
