Manjaro SD card boot issue

[aeastw]

Err,, I am more and more convinced that mrfixit's  Uboot is the best
If mrfixit will boot from SD, it's really simple
(note /dev/emmc = /dev/mmcblkX, be sure to use lsblk to get RIGHT X)
1  Save mbr or gpt mbr (the mbr on emmc),, either sector 0 or sector 0-33 (using dd of course)
2  dd if=/dev/SDcard of=/dev/emmc bs=1M count=16
3 sync
4 restore  mbr or gpt mbr, again using dd

Thanks @wdt ,

I'll give that a go! I started going down the rabbit hole of trying to compare differences between the different u-boots out there. From what I can see there are three main versions of uboot used in the pinebook pro images:

• mrfixit (forked from rockchip, with patches)
  
• ayufan (forked from rockchip, with patches)
  
• the one that manjaro uses (Forked from mainline uboot with a few patches)
  

I have done a bit of uboot development with work (for a custom NVIDIA SOC based board) and would quite like to try and get more familiar with the pinebook pro setup.
