Hey, I got Discovery F3 board, i wanted to start project which uses I2C communication, so i enabled I2C1 peripheral and generated code for EWARM IDE using CubeMX. I uploaded code on board and pressed GO in debug options, than i press HALT in debug options and i got error "Communication error message , Target is running, failed to stop the target. Maybe the target needs to be reset" after this error i can't upload code and i got error message "Fatal error, ST-Line, No MCU device found Session Aborted" . (after that i need to disconnect board, if i want to upload code.)

I didn't and any code to generated code. But i find that, if i comment "MX_I2C1_Init()" , debug works and i don't get error messages. And i tried using I2C2 peripheral and also i didnt get error messages. 
If there is problem with CubeMX and its generating bad code or i have set something in options wrong?
