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''Or''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 GNDI've trying to use  ST-Link Utility and I've got the error again #stm32-error-debug

Since it happens in the ST-Link utility, it must be some sort of USB hardware, USB power, or USB driver issue. Assuming the ST-Link itself isn't faulty.

You'll need to use the process of elimination to troubleshoot. try the ST-Link pod on a different computer, try a different ST-link, etc.

My vcap pins are about 2.7V. What can be? I've measure all pins, and the voltage are correct. My VddA and VssA are supplied.

The VCAP pins should be at 1.25V, sure you have the part correctly orientated, or have some voltage coming from somewhere else?
