How can I write custom image to eMMC ?

I created a Linux System with Buildroot. And I want write this image to Beaglebone Black’s eMMC. I can write sdcard.img to a SD card and BBB is running whit this card.

How I can write this image to Beaglebone Black’s eMMC?


I found a couple of sites that may interest you.


P.S. I know you already got the image you want. This may be a way out of not having to get new images. Enjoy.

many ways, you can smt the emmc off the pcba, and soldering it back. lol

but you can also boot with SD, copy img into your rootfs, or wget it, then use dd

dd if=/path/to/your_image.img of=/dev/mmcblk0 bs=1M

where mmcblk0 or 1 depending on your kernel.

Ooh and Hello,

I think I saw something on Freenode where this fellow was discussing this issue. Go to your uEnv.txt file and uncomment the line that states (if this build you made has this line):


##enable Generic eMMC Flasher:
##make sure, these tools are installed: dosfstools rsync
#cmdline=init=/opt/scripts/tools/eMMC/ <----- This line!


See the above line that states “##make sure, these tools are installed: dosftools rsync.” Install those tools.
