Error booting kernel

Hi all,

 

I have the i.MX53 QSB and am trying to get Android running on it. I downloaded the bsp from Adeneo and, with some effort, was finally able to build and flash Android, U-Boot and the Linux kernel with the scripts they provided. But now I am trying to boot the board and getting a CRC error loading Linux... 

 

MMC read: dev # 0, block # 2048, count 6144 partition # 0 ... 

6144 blocks read: OK

## Booting kernel from Legacy Image at 70800000 ...   

Image Name:   Linux-2.6.35.3-01073-gae8eee1-di

I made no modifications to the boot parameters in U-Boot. So they should be the working default. But I dumped the memory at the entry point for the kernel, and it is not what I expect to see.

That does not look like the start of the kernel to me. Any ideas?

 

Thanks
