@Ragorh there is a little bit of a discussion on the existing functionality on this thread, and we should have a brief usage guide added to the libDaisy docs within a week or so.
Given that we’re still in the early process of working with the bootloader, the process itself is still likely to change a little to make it a bit simpler to work with, but once the guide is published, we’ll keep it up to date as anything changes.
