The steps for saving off your eMMC contents to a file:
- Get a 4GB or larger uSD card that is FAT formatted.
- Make sure that the partition on the uSD card is marked as active.
- Download beagleboneblack-save-emmc.zip and extract the contents onto your uSD card.
- Eject uSD card from your computer, insert into powered-off BeagleBone Black and apply power to your board while holding down the S2 button (release button a couple seconds after boot).
I am trying to backup eMMC image from BBB by using SDHC 4GB that is FAT (FAT16) formatted with active state.
I downloaded the file “Beagleboneblack-save-emmc.zip” and extracted the contents onto my prepared uSD card
However, after following next step of “inserting into powered-off BBB and applying power to my board while holding down the S2 button” ,
I cannot notice USR0 start to blink steadily. Rather USR1 and USR3 blink shortly at the same time once and then just USR2 comes on
