there is another thread here *Duplicate BeagleBone black setup*

Nov 28, where you will find a solution to your problem.
Good luck.

So in that other thread, it was instructed to use the same dd command "dd 
if=/dev/mmcblk1 of=/mnt/BeagleBoneBlack-eMMC-image-$RANDOM.img bs=10M" to 
create image, so why would mine only end up 2GB instead of 4GB?  I cannot 
follow those instructions exactly, as I only have a 4GB SD card, so maybe 
this is the problem since the eMMC is 4GB also.

[beagleboard] Re: Having problems cloning eMMC

[Graham]

I think you will have two problems.

First, you can not put a 4GB file on a 4 GB card, because there must also 
be room for the 
Linux OS, and depending on the version, this can be another 1 GB, or more.

Second problem is that when you install a 2 GB image on a 4 GB card, the 
partition as
installed is typically about 2 GB, and the rest of the card can not be 
used, until you
expand the partition to the full size of the card.

So, for working with the 4 GB eMMC version of the Beaglebone Black, you 
must use
at least an 8 GB card.  I use 16 GB, so that there is room for about three 
images
that are not compressed.  You can not go larger than 32 GB at this time.

So I got my 8gb flash, and resized original boards partition to be smaller 
than second board.  So now the problem is I have flashed new board, and it 
will not boot up.  I can mount and view both partitions correctly, and 
everything looks ok, but I only get "CCC" when trying to boot and viewing 
with FTDI cable.   Any ideas?

Re: [beagleboard] Re: Having problems cloning eMMC

[Graham Haddock]

Did you set the "boot" bit on the 8gb flash card?

The later versions of the OS can not see or boot from the uSD card unless
the "boot" bit is set.

The "CC" string means that the BBB can not see the card, and is trying
to boot from
the serial port.

It is not a uSD but internal eMMC. And you can see from fdisk output boot
flag is set.

I'm not sure what you mean by bootloader.  But I just read in entire 
mmcblk1 (When booting off a SD card to image) on one BBB using dd, and 
output to another using dd.  

// BBB 1
dd bs=4M if=/dev/mmcblk1 of=image.bin

// BBB 2
dd bs=4M if=image.bin of=/dev/mmblk1

At which point, it's likely your original "/dev/mmcblk1" didn't have
the bootloader installed either.

So the original BBB does boot fine.  But how can I re-install bootloader 
for BBB2?  But it is my understanding, the bootloader is what is in the 
Fat32 partition?  It looks the same as the other one.
