Gotcha. Shame it’s not a ubiquitous thing (across all microcontrollers actually) as drag-and-drop bootloading would be sooo much easier for people just getting into things. As you outline in your thread, that can be such a barrier to entry where setting up the environment is the biggest hurdle and if you don’t know how to trouble-shoot things (and even if you do!) it can fail silently.
Super appreciated.
I’ll continue searching as well, but with all the variants it seems tricky to google info that relates to the exact variant/board.
