putty_stop_kernel-3-7

We followed the manuals of RocketBoards.org to compile and bake a linux kernel, root filesystem etc. But if we create our own SD-card image of these parts booting on the Arrow SoC kit fails. In the next step we used a working SD-card image from terasiC and updated it only partially. Everything works fine with our self-compiled root filesystem. All the other parts, especially the kernel, don’t work with the SD-card.
For our self-compiled kernel (dylan-altera from [1]) we get the following error message when booting from SD-card after the attempt to read the uImage:

“Wrong Image Format for bootm command
ERROR: can't get kernel image!”

We followed the instructions given in [3]. 



For our self-compiled kernel (kernel 3.7 from [2]) we see the following when booting from SD-card after the attempt to read the uImage (start procedure stops at this step):

- for the output see the attached png file 'putty_stop_kernel-3-7' -

We don’t see our mistake because we followed the instructions of RocketBoards exactly and all the other parts on the SD-card image as uboot work fine.
