Error in initializing ST-LINK device in all boards

i have been using stlink v2 for a while now, but today it wouldn't connect with any of my stm32 boards the error mesage that apears is

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

Is it genuine STM or V2 "stick" ?

Connect with CubeProgrammer and show, what its telling.

Ooo.. target : 0,52V - that cannot work !

power your target to 3v3 and try again. (or you forgot to connect the vcc sense to st-link ?)
