Minor changes to build successfully in /include/configs/mx53_xxx.h Well, you made a lot of changes. I think you use 2009.08 from Freescale tree, and there are a lot of differences with mainline tree. Maybe it is worth if you check your code with the boars already supported by U-Boot mainline having the i.MX53 SOC (Freescale's mx53-loco, -ard, and -smd for example). > > I’ve ported flash_header.S to imximage.cfg. > I’ve moved our old /board/freescale/mx53_xxx/mx53_xxx.c to the new u-boot > directory, setup the pads using the new nomenclature and modified the > library includes to use the new ones. > I’ve moved include/configs/mx53_xxx.h file to the new u-boot directory and > made the necessary edits to build successfully. > > I’ve triple checked the pads and flash header.

I am afraid that it is too difficult, because it depends on your custom hardware. Next step should be to attach a JTAG debugger to see what is happening.
