NanoPi R6S not booting from eMMC

[AndrewL733]

I just wrote the Armbian Ubuntu Jammy Desktop image to an SD HC card and booted up fine with it (although I can only boot if I disconnect the HDMI cable -- when boot up is finished, I can plug it in and use the desktop.  That's another story, but I have the same issue with official NanoPi Ubuntu images. 

 

Next, I transferred the Armbian OS to the eMMC and indicated that I wanted both the boot and system to be on the eMMC.  After transferring the rootfs and getting the Power Off prompt, I powered off, then removed the SD HC card, then attempted to boot.  However, when I tried to power on again, the NanoPi went into a reboot loop.  Armbian will not boot without the SD card inserted.  I just get a splash screen and a few lines of text and then it cycles all over again. 

 

I booted up again with the SD card looking at the "df" command, I can see that the OS is actually on the eMMC, but the /boot  partition is still on the SD HC card.  I attempted to update the bootloader with the armbian-install command -- it only gives a single option to update the bootloader on SD/eMMC (doesn't give a way to choose between those two devices).  That didn't solve my booting problem.  I still needed to have the SD HC card inserted too boot.  Then I tried the OS transfer again and that didn't work either. 

 

Is there a solution to this? It seems the Armbian installer just can't properly update the eMMC so that I can boot from there.

Quick update.  I solved my problem.   I was running armbian-install over ssh, and when I got the prompt to shut down, my ssh session was ending immediately and I was just ejecting the SD HC card then.  When I actually waited for the NanoPi r6s to turn off, all was good and on my next boot (with the SD HC card removed) the NanoPi booted up from the eMMC.
