I had a working serial cable and development plug to play around with so I thought I would try out the new UBOOT from late last year with my Plug (the Pink E02 one) - and possibly try out the NAND based rescue environment as well. (why only turn one dial)?
OK, being a fairly cautious person, I first recorded my initial environment variables.
Here they are:

I then flashed the updated u-boot from the instructions here
http://archlinuxarm.org/forum/viewtopic.php?f=53&t=8857
I believe I typed "pacman -S uboot-pogo_e02" and answered all the questions with a yes
BEFORE REBOOTING, I also followed the instructions for creating the "rescue system" (specific to the E02) here
http://archlinuxarm.org/forum/viewtopic.php?f=30&t=8383
(basically following the instructions to the letter, including the section at the end specific to the E02)
So, I then rebooted and what used to work - now, no longer will work.
Here is a sample output of the plug as it attempts to boot, as well as the new environment variables.
Does any have any ideas? Thanks
I'm just before throwing it in the trash
