@azgael,

The programming is done with the standard SWD Arm interface. There's a wiki page on a similar project that I hope is a good starting point. The programming connections are exactly the same. Other pages on that same wiki might also be interesting.

Once the bootloader is flashed via the SWD interface, you should be able to connect the Sugarboat via USB-C, open the PlatformIO project (code/sugarboat/) and flash it over USB using UF2. If I remember correctly I did it from VSCode using the PlatformIO extension.

In the README there's a link to some of the clients I wrote a couple of years ago when I was actively working on Sugarboat. One of them is an ESPHome (and Home Assistant) integration (see clients/esphome/sugarboat-bridge.yaml)). I have a different setup and I haven't used it since, so you may need to do some adjustments for newer ESPHome versions.

Good luck!
