Ok.

What is loadaddr set to? Does it fail with loadaddr set to 0x81000000?

When trying to load an ELF with bootelf, I'm not sure what different versions 
of U-Boot do with regards to giving you an error if it unpacks the ELF over the 
top of the ELF.  How does elfloading work with a loadaddr of around 0x84000000?

Which Jetson-tk1 board are you using?
