There are two options for how to implement USB startup support. The first is to do everything automatically, i.e. the user does nothing manually (minus - there will be no compatibility with the official versions). The second option is that some of the operations need to be done manually (copy DTB to the root of the first section), there will be compatibility with the official versions of khadas images. The question is - which is better ?     https://users.armbian.com/balbes150/ked
