Sorry for top post. This is the third message of the thread being re-sent in plain text. I'll also add that the test case below also hangs on trying to bootm a kernel in flash just as it did in the nfs boot case of the shown below.

I guess I don't understand at all why flash_addr_new + CFG_ENV_SIZE is getting saved off when I want my redundant environment to start at flash_addr_new.
So, I went back to the other test case I'm trying where my CFG_ENV_SIZE is equal to flash sector size (256k in my case) which makes the redundant environment work but when I try to NFS boot my board I get:
=> run fixed_nfs Ethernet PHY auto-negotiation complete Ethernet link: is up Ethernet link: Full-duplex mode Ethernet link: 100 Mbit/s Using pc20x_emac device TFTP from server 192.168.0.2; our IP address is 192.168.0.5 Filename 'uImage-cpe20x'.

And then everything hangs. Should I play with moving around TEXT_BASE (0x05000000), linker files? I'm kind of stumped at the moment. :(
