Flashing NanoPi M4 eMMC

Moderators: chensy, FATechsupport

I have the microSD to eMMC adapter. I've tried flashing the Friendly Desktop sd and eflasher .img files using dd. In both cases, the M4 will boot from the eMMC (green LED blinks), but I get no desktop video. HDMI is putting out a signal of some kind, but my Dell 1080 monitor shows only a blank screen. I can dd the sd image to an sd card and boot that without problem - video works fine on the same monitor.

What is the procedure for writing a Friendly Desktop image to an eMMC card using the microsd to emmc adapter?
To answer my own question: It can't easily be done.

Two options:
Create a boot microsd from the eflasher images, boot that, use the eflasher program to write the emmc
Use a typec image with the Linux_Upgrade_Tool to write the emmc using instructions from the wiki

Untested, but I think once the above methods are used to write an emmc, you could move the emmc to a microsd adapter and capture the image with dd, then use that image to flash additional emmc modules.
I have nano pi neo4 and I am unable to boot it using emmc , with sd card I can boot rk3399-sd-friendlydesktop-bionic-4.4-arm64-20191227.img, could you please elobrate more how can I boot from mmc...?
