SEGGER J-Link programmers/debuggers are very common SWD tools. It looks like we need a platformio "tool" to download the binaries from segger so that a custom platform can be made to use it. I'd like to take a stab at this but I'm not sure where to start.
There are docs for how to make custom platforms/frameworks and boards but none for custom tools as far as I can find.
I tried to find the source for
tool-avrdude as a place to start and was also unsuccessful there.
Could someone point me in the right direction?
