Maybe ... I don't know since my PineH64 is equipped with eMMC yet, I've asked @tllim if he could provide me a sample so I can narrow the issue.

Thanks for looking into it. In the interim, does anybody have any pointers for repairing the u-boot install on eMMC? The furthest I have gotten is getting u-boot installed and attempting to find the kernel/root partition (I am not sure which is failing). There aren't specific offsets that u-boot is using to find root partition right? My understanding is that it should just check the target partition for Image or zImage in `/` or `/boot`. any old ext4 or btrfs partition should work?
TIA
edit: after some more iterating on various configs, it is pretty clear that it is a kernel build issue. Android 9 starts from mmc fine, AOSC 02-16-19 also. But AOSC 07-09-19 and the armbian images do not boot. They seem to load the kernel, then go awry when they need to read from mmc. However, in AOSC 02-16 the neither the NIC nor the wifi work. Seriously tedious. When I boot Armbian from SD, everything works. Except the eMMC.
I will make a pass at building a new kernel from the 5.90 kernel sources, but I am just throwing darts at this point.

Except the eMMC.I've received my eMMC module today, I had on my SDCard Armbian Stretch with Linux 5.4.0-rc8-sunxi64, so I've simply erased partitions already present on the eMMC and ran "nand-sata-install", halted the board, removed SD and rebooted, it rebooted from eMMC without any issue.
I'm now building 5.4.2 and will update my PineH64 Model B in the next hour ...

I have manjaro-arm booting fine from eMMC. I wrote it to eMMC with suse image writer and it booted straith away. What I notice it takes some time before I see something on the screen. I don't even use Pine eMMC but an old one from a Odroid C1.
RE: eMMC boot help - Neko May - 12-30-2019
I have tried two images with the eMMC module:
- The new Armbian images for the Model B built 25-12-2019
- The AOSC image on the PINE64 wiki from September 2019
Neither boot from the eMMC module. Armbian hangs at attempting to mount the root filesystem. AOSC reports a data error on the eMMC, pauses, disables IRQ 96 then hangs in a kworker thread trying to use the eMMC module.
UPDATE: NetBSD can access the eMMC no trouble booted off the SD Card, Linux can NOT; there's a kernel bug afoot.
