Cool change! Saving people from BL download protocol is a great idea. |

I have no motivation to add UF2, if someone wants to make a PR; this should make it easier (once I get it all cleaned up and do more testing). What would the use case for UF2 be here? |

Agreed. They're pretty close, technically, and this moves the ball pretty far. Skimming the code, it's a great update. UF2 has a lot of tooling & developer mindshar right nowe. RP2040 (? Pi Zero?) burns it into mask rom as the official flasher. NIfty thing is that it can do containers, as for resources (icons) to store at different addresses, multiple images for different devices (V1, V2 of similar hardware or different compile images for different memory layouts) in the same file that are sussed out at load time, etc. The device is somewhat responsible for choosing it own adventure on which parts of the image to request and load. It's sector/block/page oriented instead of a stream of bytes. Incremental flashing to reduce sector wear. I helped on an STM32.implementation. It's pretty clever. Its better thought out than you expect a Microsoft technology to be. "Don't care" is perfectly legit. :-) |

So this all seems to work for me locally. Going to get @gamelaster to poke the windows builds as I dont have a Windows machine here. |

Yeah this should set us up for handling more in the future. I gues only refactor outstanding would maybe be to support multiple chunks. But that can wait to see if we get a need for it. I'm definitely in the dont really care bucket at the moment for a new format, but if someone gives a good use case; I'm happy to look into it. I think UF2 could be good option later on; but will wait for a use to show up :) |

Hia,
This brings in a base for
.dfufile support.These are great as they are basically a standard for putting headers on
.binfiles for us to know things like address.This has been tested locally with the
.dfufiles from IronOS but more testing ongoing.
