So, after a bit of reading docs and messing around with stuff, I got CE KITL working on the Titan over USB RNDIS. No dice on the Diamond/TP though.
So now, in platform builder, I get a nice shell:
I can enter commands from here, and watch debug messages on this otherwise non-functioning Titan (as you can see, GWES is nonfunctional in this ROM). For those who have no idea what this is, just know that it will accelerate development for devices, it is very useful for understanding how driver level stuff works in real-time.
Instructions follow… soon!
