Well, I did wait, although I did not really have a working U-Boot... But now I think I got one - even though the issue with the eMMC frequently not being available persists. Currently I'm just running a system from SD card, a Manjaro that I installed with the manjaro-arm-installer running on an AMD64 notebook (on Debian). I had to remove one check from the script, and cancel a stuck process with ctrl+c at some point, but it gave me a bootable system.
It seems strange to me, how many images available on the PineBook Wiki, i.e. the Manjaro ARM with KDE (Plasma) desktop, do not actually boot my PineBook.
I did quite some experiments, going as far as trying graphics for U-Boot on the SPI, and using a bootable Nix Linux (and the effect of early graphics and having a boot menu is great!)... but nothing helped with the eMMC issue. At some point I even had a system that would run from SD card, but for some reason had super slow access to the card only (around 1 MB/sec, if I remember correctly). Now "hdparm -t" shows 58 MB/sec for the SD card, and 179 MB/sec for the eMMC. So really I'd still like to use the latter. I'm also considering complaining about a broken product (maybe a replacement part could fix the problem?), or buying the NVMe adapter...
