RE: [Ltib] Puzzle: Booting hangs after tranferring from U-boottoKernel

[Stuart Hughes]

Hi Mike,

LTIB is not a factor here, it's pure down to you to pass the right
command line args to u-boot.

With the older u-boots you don't pass the dtb, with the new commands you
use a - as a place holder:

bootm $loadkernaddr - $loaddtbaddr

Please ask on the u-boot list for clarification.

Regards, Stuart
