When I connect my board to my computer via usb (cn2) I lose the programming. I lost the factory programming to start with. I downloaded the Keil uVision5 compiler and downloaded the blinky app to the discovery board. It works until I either unplug the usb cable and plug it back in or shut my computer off and reboot. Has anybody else had this problem? If I program my board and unplug the usb cable and plug it into CN3 (USB User) it runs properly.

Hi smuts.tom,
I recommend you to upgrade the ST-Link firmware version to V2-1 through this -Hannibal-2016-06-23 08:23 AM

I have version 2-1 installed. I need to know whether it's my computer or the Discovery board so I ordered another board. I'll know Monday which it is.
