After Flashing eMMC, Will Not Boot - Mossbot - 09-27-2022
Hello,
I was following this guide to utilize my new NVMe drive.
When I flashed the eMMC from an SD boot, everything seemed to go well.
After shutting down, it will no longer boot. If I hold the power button for 20+ seconds, then press the power key, the red LED flashes but nothing is happening after that.
I've tried booting from the SD with and without the eMMC installed. I've also tried flashing the eMMC with the USB adapter.
I thought flashing the eMMC was a safe operation to perform. Am I missing something.
Any help is appreciated.

I should mention the image I was flashing was "Manjaro-ARM-kde-plasma-generic-22.08.img.xz".

OK, how do you know that a "generic" image is right for pbp?
Very likely the dtb is not right, the dtb is specific for different hardware
uboot is a very minimal bios, the dtb is much more specific
uboot only sets mem at a safe speed, initializes com, initialize (storage) media
and searches for config file, and then copy kernel, dtb, initrd to specific memory locations
and that's it
so,,, disable/remove emmc, do hard reset (20s press), try to boot SD
does it boot?
Use an image for pinebookpro, and MOST specificly NOT pinebook, this is completely different cpu
An easy mistake to make

It was mentioned on the Manjaro ARM forum that the you have to use the generic image for the Pinebook Pro.
I can't find that post so quickly.
But when you go to the download page, Pinebook and Pinebook Pro are not in the Devices list.

maybe this will boot
https://github.com/manjaro-arm/pbpro-bsp-images/releases/download/factory_22.06/Manjaro-ARM-kde-plasma-pbpro-bsp-22.06.img.xz
i don't know what it means but

FWIW, and I am using 5.8.14 for the sleep functionality
When I go to the dtbs directory a ls -l| wc -l gives 31, when I
do md5sum and uniq and wc -l it is 29 (these are all for rk3399)
Nearly all of these are for SBC which do have slight variations
And notably only the pbp has an attached display rather than a hdmi socket
Maybe a later kernel is more "generic" , I don't know
Given the variations though, I would think a specific image would be better
