@balbes150 Perhaps this is slightly off topic, but as a Linux engineer I work primarily on CentOS based systems. CentOS does provide an armhfp based image with various pre-canned uboot images and dtb files that can been used to install uboot with their uboot install utility. None of them seem to be for amlogic s805, meson808b, mxq or anything I can identify as similar hardware. Are there other boards or labels I can look for? I'm a complete uboot novice, but I think if I were nudged in the right direction, I might be able to at least experiment with CentOS or Fedora in addition to Armbian.
Thanks!
