can you check whether you might get an overlap of your uImage when
loaded to memory (from sd-card or network) and the final system image
copied to bootstrap's linking address?

You might check your final uImage with: 'mkimage -l uImage'
and the 'loadaddr' your u-boot boot-script finally uses as argument for
'bootm'.
