Error in initializing ST-LINK device.

Reason: No device found on target.

 

i have no clue what it could be, i tried in two different pcs with stm32 cube ide in the 1.17 and 1.18 version, i have tried updating the stlink software in the cube ide , in the programmer and in the st link utility, nothing is really working, the boards are fine cause i can connect them to the st programmer using usb.

Need help, Thanks
