[Barnes & Noble Nook Tablet] highfly22:
I managed to execute a customized kernel. But it hangs in somewhere.

The main trouble is l2 cache. The l2 cache may crash the kernel in the somewhere. I am inspired by hkvc. http://xdaforums.com/showthread.php?t=1427610

Did you meet this problem?

Here is output from uart:
