Sorry, i read and see " If you want to generate an image file that can be flashed to eMMC you need to generate a boot.img file and copy it to your installation SD card". Maybe it only with some nanopi boot with eMMC? What's about nanopi fire2, it boot from sdcard? what must we do to add my new image? I replaced it in boot section, but nothing changed. Can you help me for detail, thanks very much.
