[Bug 506761] Re: lucid uboot hangs on fatload uImage on fsl TO2 TO2.5 and TO3

[Alexander Sack]

i can get a working image it seems using the following steps:

 1. get a current redboot lucid image; put that on the sd card

 2. get the current uboot.bin from archive

 3. sudo dd conv=notrunc if=uboot-imx51_to3.bin of=/dev/mmcblk0 bs=512
skip=1 seek=1

 4. copy the uImage produced by our script uboot-image-script to the fat partition:
        cp uImage /media/4B4C-AB5E/

 5. check the uImage: (optional step)

mkimage -l /media/4B4C-AB5E/uImage

 6. umount, plug sd into board and load to success:
