Then, system hung.

The uImage is build by using TQM8260_config.
Q1. Can the uImage build by using TQM8260_config can be used on sbc8260 board? If can not, which config I should use?
Q2. I marked several places above by "<<--??". Any one see those before? If you do, please let me know how to fix them.
Thanks,
dd
