How can we flash the Ubuntu Xenial image.img without using Neutis Flasher ?
Do you want to flash eMMC, not SD card?
Basically, the same process as most other embedded linux devices use.
The easiest way is to boot from SD card and flash eMMC (/dev/mmcblk2) using “dd”. You need to download an image to Neutis before. Is it acceptable for you?
dd if=image.img of=/dev/mmcblk2 bs=4M status=progress iflag=nocache oflag=nocache,dsync
