With your current layout, parts of the bootloader may be written to the same offsets as files in your first partition... you may have gotten lucky for now, but it's only a matter of time till something breaks your bootloader! You really want to have the loader1 (start sector 64, 2.5MB size) and loader2 (start sector 16384, 4MB size) partitions listed in: http://opensource.rock-chips.com/wiki_Partitions gptfdisk/gdisk should be able to write such a partition table (at least the loader2 partition, some tools refuse to create the loader1 partition starting at sector 64). Glad you made good progress! It would be nice to eventually be able to create installer images for aarch64/armhf... there's been a lot of progress on being able to create cross-compiled installation images, so the day may not be so far off! live well, vagrant
