I decided to update to the latest ArchLinux ARM on the DockStart, and try your latest Uboot and default env files with it. But...after flashing 2015.10 Uboot and the envs, neither Arch 3.6, no Arch 4.3, and neither original Pogo OS preserved on Flash are able to boot. Had to open the box and run serial. Here's what transpired:
a) with original Pogo on Flash:
b) with old Arch 3.6
c) with latest Arch 4.3
The above shows that your default env doesn't work with Arch. Is DTB file required for Arch 4.3, and where to get it? Pls consider adding a separate section or thread about installing your Uboot for Arch, and adjusting default env respectively. Also important to explain how to preserve original Pogo recovery on Flash in this scenario, and add corresponding evns.
Re the above printout, what should I change to boot each of the above OSs?

moderator edit: made this its own thread.

The above shows that your default env doesn't work with Arch. Is DTB file required for Arch 4.3, and where to get it? Pls consider adding a separate section or thread about installing your Uboot for Arch, and adjusting default env respectively. Also important to explain how to preserve original Pogo recovery on Flash in this scenario, and add corresponding evns.
Re the above printout, what should I change to boot each of the above OSs?
