Anyone come up with a standard for flashing code on to on-module microcontrollers without requiring the module user to do something unfriendly?
Background: I’m looking at a few modules that will need on-module MCUs (at least one of them will have very complex logic in the helper MCU). I can use jtag or isp at home, but if I were to ship those as kits, people would need some way to update them using nothing more than what a typical Gadgeteer dev would have, preferably without requiring them to disassemble anything.
Not talking Daisylink here, but if that already includes something to help, I’ll definitely consider it.
Ideally, it could be done as a program loaded on the mainboard and then sent to the module. I can think of a number of ways to handle this, but wanted to see if someone else has already paved this ground.
