Last try on Armbian: https://dl.armbian.com/odroidc1/Buster_current_minimal
The image now contains uImage OOTB. The boot.ini however is unmodified. Not sure if something has been fixed or not, however if someone can test it and it boots, I’ll create a DietPi image from it, otherwise I’ll use ancient Meveric kernel 3.10 image, which should at least boot.
