Yes, I have a bit of experience with mis-matched uboot-OS, different than you
I suppose it could be a hardware problem, but you are sometimes getting boots - emmc recognition
I assume you have checked that emmc is seated in its socket, or tried unplug - replug
You could setup pbp like mine, until you find a satisfactory uboot,, emmc 1st 16M blanked, mbr restored
Then, the only uboot is on SD, lsblk and dmesg | grep mmc to see what is happening
Then, try 'satisfactory' uboot ONLY on SD to see if will boot emmc (blank mbr on SD, note sector #s)
Sometimes a couple second pause seems to make a difference, I don't know how to set this up

(the point to doing all uboot experimentation on SD, if you screw up or something badly mis-matched, easier to recover)

The cpu has only enough memory to run idbloader
I suspect your failed installs have put part of the uboot package on emmc, but not all
Try seeing what uboot tells you with emmc removed, you did get a successful boot with only SD
If I am using an EMMC to usb reader to flash. It is always recognized. I doubt it is a Hardware problem with the EMMC. The EMMC always makes it to uboot. My uboot is on the EMMC, and once I am in, it works the whole time.
I inspected both male and female sockets with a microscope and found some flux bridging 2 pins on the socket in the pinebook. Cleaning this made no difference.
The BSP uboot fails for me 100% of the time. It will faill with only a single failure to connect the EMMC.
The most recent pinebookpro-uboot from the manjaro repo seems to work more frequently than the others, but still fails too often.
I would post some pictures, but the file size limit here is too low, and my adblocker isn't letting me upload to imgur.
I am about to flash again, because I can't get past uboot with the BSP uboot I currently have installed.
Someone on here also recommended me some other uboot to try.
Ultimately, I feel like giving up on this thing and putting it on the shelf for a few months.
It's pretty frustrating working on this for over a week and still can't boot more than 3x in a row followed by not booting 10x.

Here are a couple of pictures. The success shows manjaro booting after a single error 110 with the manjaro uboot, and the bsp uboot failing after a single error 110. After a few boots, I will exceed 4 error 110's on manjaro and begin failing to boot.
