I am trying to connect my stm32f103C8 via usb, when I did this I got the following message "Error in initializing ST-LINK device.

Reason: (4) No device found on target".

I try to update it with the stm32utility and it doesn't recognize the card.

How can i fix this?

Make the target functional and connect it properly?

For an external ST-LINK/V2 make sure pin 1 is connected to the board supply and the voltage is correctly reported in the debug logs of the ST-LINK Utilities.

Check SWDIO and SWCLK pins.

Check supply pins on chip

Check NRST level

Check chip orientation

Perhaps explain your system with more detail?​
