[Ltib] Puzzle: Booting hangs after tranferring from U-boot to Kernel

[Qin, Laigui (GE EntSol, Security)]

Hi all,

I have successfully porting U-boot for my custom board. Now, I am trying to boot the uImage built from the Ltib for M54454EVB (I plan to modify Ltib based on the M54454EVB, while I am not using its Uboot in Ltib). The booting hangs after tranferring from U-boot to Linux Kernel. Any one can help on this?

And anyone knows the "Bumping USB Priority"? This come before the "Linux version 2.6.23..." in M54454EVB booting...
