Agreed. In this case, the vendor doesn't ship a working kernel at all. Their view is that the community will handle that. Massive props to ayufan, without whom

Agreed. In this case, the vendor doesn't ship a working kernel at all. Their view is that the community will handle that. Massive props to ayufan, without whom most of the Pine SBC's would likely have no bootable image. I experimented with a RockPro64 a few years ago before learning this lesson. The hardware sounded wonderful. Unfortunately, there was some kind of conflict between the PCIe slot and the GPU. It was possible to get hardware-accelerated video, or use the PCIe slot for additional SATA slots, but not both at the same time. I spent a fair amount of time trying to dig into it, but never did establish whether the problem was in hardware, the device tree, or the drivers.
