I downloaded the USB boot loader (generic_boot20_pc13.bin) to STM32 Blue pill and I am able to detect the board in Arduino IDE. But when I flash the simple blinky code to board from Arduino IDE, the board looses connection. When USB boot loader is flashed again the board detects. Looks like I am missing something while programming boot loader or application code. Can someone help me on this?
