Hi Steve, nice to see someone putting effort on this. I agree that something more related to OpenOCD makes it seems more "standardized". But I honestly can't evaluate it against what NuttX readme suggests. Regardless of the way it evolves, I believe it worths to bring it to NuttX Workshop as an introduction to your work and as a "current state of the art".
