ALL the scripts assume you are directly "running" the image from a
fresh bootup, that you would like to "copy" to the secondary storage.
Don't do anything fancy beyond that.

No, it didn't even boot, the single (power?) LED came on but that was
all.  Had me worried for a minute but without the boot button down it
acted quite normally still and booted Debian 7,

I think you're spot on actually!  :-)   I didn't stare all that hard
at the code but it certainly did seem to copy from the eMMC to the
microSD card.

Yes, my Debian 7 does automount SD cards.

OK, thanks, that does seem to make sense to me.  I'll need to wait
until I'm next back on the boat which will be a week or so now.  The
boat is in France and I'm in England, it's not just down the road! :-)

I don't have that script in the existing Debian 7 installation:-

chris@odin:~$ ls /opt/scripts/tools/eMMC
beaglebone-black-make-microSD-flasher-from-eMMC.sh
chris@odin:~$ 

Should I run it from the mounted Debian 9 image?

OK, thank you.

As I said above I'm away from the boat for a while now, I should be
able to retry in a week or two.
