I figure that would be the same or similar.

Updated the u-boot version to the date of today. I insert the sd-card and press the power button, it starts blinking. What does this indicate? The caps lock led is not active at all. I seems like the u-boot on my sd-card is never executed or invalid. The caps lock led would indicate if u-boot is running, right? I used your line to copy u-boot onto the sd-card. dd if=ubootsb.bin of=/dev/mmcblk0 skip=1 seek=1 bs=1024 > If we're at the point we're having more trouble at this point please > give me a nudge and I'll create a solution for rescues that will suit > your exact situation.
