Portenta machine control - Help getting started

Ok I bought a Portenta Machine Control module (one of the new ones). But I am having a hard time finding any real information on programming or using it anywhere. I can download programs to it and can get serial data in and out, but for the life of me I can't figure out how to toggle an output.
I would assume a simple Blink like program would work, but I can't seem to figure out the pin mappings from the Portenta module to the machine control breakout board. I would have thought that this would be easy to find, but all I seem to get is marketing material and a basic data sheet on the board. Any help would be appreciated. It is driving me crazy and I'm about ready to box the thing up and forget about it.

There is a section of the forum just for Portenta.
