Thread:Talk:BeagleBone Black Extracting eMMC contents/Flash unsuccessful/reply (2)

Hi, since I spent two hours figuring out how the backup of the interal emmc storage works, here is how I got it running on a recent REV C BBB from Element14:

Copy am335x-boneblack.dtb into the dtds folder Insert the SD-card into the BBB and just power it up (no need to hold down the S2-button)
 * The SD-card really has to be formatted with FAT16, which is only possible with SD-cards <= 4 GB
 * 1) * Open a command window and enter diskpart
 * 2) * Select the SD-card as disk with select disk (list disk shows all disk)
 * 3) * Enter clear (make really sure, that you selected the SD-card)
 * 4) * Keep diskpart open
 * 5) * Open the disk-management in Windows
 * 6) * Create a new partition with exactly 4048 MB and format it with FAT16
 * 7) * Go back to diskpart, enter "select partition 1" and afterwards active
 * 8) * Create a folder "dtds" on the SD-card
 * Copy the entire content of https://s3.amazonaws.com/beagle/beagleboneblack-save-emmc.zip on the sd-card

The USR0 LED should start blinking in a regular pattern (not the heartbeat pattern)

But now the backup solution works really fine and is perfect to clone a running configuration for the BBB onto further BBBs.
