"nothing"? Did it even boot?

Given what I could understand of the script (I'm no where near a BASH
script expert -- my heaviest "shell script" experience is VAX/VMS DCL,
AREXX [Amiga REXX]... I don't consider Python a "scripting language" (AREXX
could be used to control any application that opened an AREXX message port,
and any statement in a script that did not parse as native AREXX would be
sent to the current "command host" -- ie; the shell by default or an
application if one did "address application-name" first -- and the easiest
way to make a statement "not native" was to quote the first word) -- pardon
the harangue -- I understand the script to copy files from the /booted/
system media to the other media. If it booted from the eMMC, running the
script will copy the eMMC to the SD card.
I could be all wet with that hypothesis <G>

Boot with your existing system. Insert the SD card. MOUNT the SD card
if it isn't automatically mounted (there was a period of time where the
Wheezy images would auto-mount SD cards).
Edit the <SDCARDMOUNT>/boot/uEnv.txt file (NOT a file on the eMMC) as
described
http://beagleboard.org/latest-images
Reboot. If the reboot doesn't read the SD card a start flashing, reboot
with the boot button held down! Due to the changes in device tree handling
since Wheezy, a Wheezy era eMMC uBoot may not be compatible (hypothesis --
I don't think I've used the boot button since Wheezy) and my understanding
is that the boot button totally bypasses the eMMC uBoot for the one on the
SD card (newer versions, I believe, use the eMMC uBoot which transfers to
the SD card if installed to complete the boot).
