We've had a few posts about the U-boot issue, but nothing concise. Other than a few of us with anecdotal experiences, I don't think we really know for sure that the U-boot coming with Manjaru on the latest batch of Pinebooks Pro is the problem.
I do share your stance on the unfriendliness of the problem. But I think a good solution would simply be clear instructions on how to replace the offending stock U-boot.
I think a bigger problem was finding out that U-boot on the eMMC passing off to U-boot on SD cards masks the fact that the SD card might not actually boot without U-boot on the eMMC ceding control. But I'm not sure what could be done about that.
