Hi Shuyou,

This is not 'while u-boot loads Linux', this is 'while Linux boots after 
it was loaded by u-boot', because these messages are from Linux.

I'd say these messages typically occur when the image (kernel+ramfs) is 
corrupted. What does u-boot display before jumping to the Linux kernel?

Amicalement,
