Hello and thank you in advance for the help.
I know that, in general, this topic has been addressed before. I looked
through all the posts, followed whatever methods, etc., were suggested but
I can't get it to work (it being cloning my eMMC on one BBB to another BBB).
I live in rural Canada and downloading costs me $10/gb so I am cautious
about downloading stuff unless i have to, etc..
My 'source' system is Ubuntu 13.04 (GNU/Linux 3.8.13-bone21 armv7l).
Initially my target was an 'out of the box' BBB.
I booted the 'source' system from an Anstrom 'bootable' microSD, mounted a
USB drive, in the USB directory I executed
dd if=/dev/mmcblk1 of=BeagleBoneBlack-eMMC-image-Jan52014.img bs=10M
The command completed with no errors and a reassuring amount of data copied
(1.9gb)
Then I booted the 'destination' system from an Anstrom 'bootable' microSD,
mounted my USB drive, and in the USB directory executed
dd if=BeagleBoneBlack-eMMC-image-Jan52014.img of=/dev/mmcblk1 bs=10M
Again, the command completed with no errors and a reassuring amount of data
copied (1.9gb)
Unfortunately, when I boot the destination machine, nothing much happens
except a flashing LED. I can't SSH into the board and it doesn't even show
up on my network.
Figuring there was something Ubuntu related I flashed the destination BBB
with Ubuntu 12.4, which I had around. It worked fine, however, when I
repeated the above procedure (including booting Angstrom off microSD) I got
the same result.
I wonder if there is something wrong with my eMMC partion table on the
source BBB (even though it works fine). When I execute fdisk -l I get the
following (note the *doesn't contain a valid partition table* reports)
Disk /dev/mmcblk1: 1920 MB, 1920991232 bytes
255 heads, 63 sectors/track, 233 cylinders, total 3751936 sectors

I/O size (minimum/optimal): 512 bytes / 512 bytes

I would be very grateful if somebody could tell me what I am doing wrong.
Thank you
