My very first dive into this pool. Proffie 2.2. Received a CC Saber OWK4 Carbon. But it had some weird blade styles on it, so I figured I would go back to factory styles. Downloaded the 2.2 config from CCSabers site. Used 89blue.h. After some struggle I finally got the OS program to compile. Uploaded it. It said 100%, so I powered down, unplugged the core. Tried to power back up….and nothing. No lights, no power, cannot communicate via USB at all. Did I brick it?

Hopefully not 
Sound like checking power supply (your battery)
Would be a start.
Do you see any loose wires?
Is your battery charged? A short can trip the protection circuit and it will seem dead. Some auto reset, some need to be recharged.

It did show up and was talking. But now that the board seems to have lost power it doesn’t appear in devices or communicate.
I let the battery sit for 30 mins. No change. I will try throwing it in the recharger and see what happens tonight.

I’ve had similar issues with bad configs. you can force-update by triggering the STM bootloader using the reset buttons on the proffieboard even though it will not show as a connected port. This has happened to me when it didn’t like my blade count, max leds, or whenever I try to use null blades to fill the blade array.

Thank you everyone for all the help! Bad programming it was. Flashed a Proffie 2.2 with 3.xx .Flashing it with 2.xx fixed the issue. Thanks again!
