Correct you are, but I’m SO CLOSE! My hunch is that something with the PlatformIO config isn’t quite right. I can create a new PIO project with the seed, get VS Code to play nicely with the libs, but when attempting to build/debug, things fall apart. Full details in that thread, would absolutely love a few more eyes on it.
The dream is to get PlatformIO, VS Code, and a SEGGER J-LINK hardware debugger all playing nicely.
