Hello, I really need help. I use CoIDE to made my firmwares, but sometimes I've a error when I try to program or debug my own board using ST-Link from any dev. board from ST.

I'm using SWD conection, and sometimes it is ok, but sometimes I've got this message:

"Error: Connect failed, check config and cable connection"
"Error: Flash driver function execute timeout
     Erase:     [  0%]"

I've reinstaled the driver and re-checked the conection. My this can be an error from my board?

I've a 10k resistor from reset to 3V and another 10k resistor from BOOT0 to GND, and my BOOT1 is conected to GND

I've trying to use  ST-Link Utility and I've got the error again
