Looks right from memory. I tend to keep the kernel on the same partition as 
the rootfs rather than having a separate boot partition as I find it easier 
when managing multiple rootfs partitions, but that's just preference.

Check that you're doing this in the NAND uboot (Pwr then Aux) not the NOR 
uboot (Aux then Pwr). I don't think the NOR one can save its environment, but 
I don't know what the message is if you try, so it could be unrelated.
