[clug] A simple BeagleBone question

[Eyal Lebedinsky]

I decided it is time I got to get to know my BBB Rev C. At first I want
to update the image to the latest available. It came with a Debian
system from some time in March.

I see two on offer at http://debian.beagleboard.org/images/

BeagleBone (Runs on BeagleBone Black as well without flashing the eMMC)
	bone-debian-7.5-2014-05-14-2gb.img.xz
BeagleBone Black (eMMC flasher)
	BBB-eMMC-flasher-debian-7.5-2014-05-14-2gb.img.xz

Both contain an image with the same layout (see below). I understand that
I need to put an image on a uSD card and power up the BBB with s2 pressed
etc..

I read
	http://beagleboard.org/Getting%20Started#update
and followed from there but the clearest I got was
	Download the desired image from...
	Download the image file of choice...

I do not know what the difference is (and which one I should install).

The closest I get to a clear understanding of the above statements is that
the second one is for the BBB but the first one will work ***but will not
flash the eMMC** (so what does it do? A live boot off the uSD?)
