Hi,

 

I have a T4240QDS Rev 1 that boots find with the pre-installed SDK V1.4 linux kernel.

U-Boot 2012.10 (Dec 08 2012 - 22:38:39)

 Image Name:   Linux-3.0.51-rt75

See attached file "t4240qds-bootlog-sdkv1.4.txt"

 


=> bootm e8020000 - e8800000

But when I download the SDK V2.0 kernel and FDT, u-Boot seems to hang and does not start the kernel

Any help welcome
