I have prepared my sd-card for Ubuntu-boot using the script on this website
sudo ./setup_sdcard.sh --mmc /dev/mmcpklb0 --dtb beaglebone When I boot my beagle Bone, I think I can book with Ubuntu but now I want write it on the eMMC, how is it possible ? I have tried writing pre-built image on sd-card and then booting with it to write it on eMMC but it does not work ? Any ideas ? Thank you.
