[U-Boot] uboot for zyxel nsa320

[kqt4at5v at gmail.com]

I have a new Zyxel NSA320. It is unmodified. At the uboot prompt I 
printenv and save all environment variables. Next I pulled code from 
https://github.com/psch2/uboot-nsa320, compiled and used kwboot to load 
new uboot. No problems so far. Now if I reload all environment variables I 
saved and boot the kernel loads but does not execute. Any ideas?
