Program Check Exception reports about hardware problem on your board. Usually incorrect board initialization produces similar problem.

Check memory configuration, , NAND Flash enabling on your board.

Configuration of the u-boot is available in the following folder in u-boot source: /include/configs/.

See the following page:

Have a great day,
