Hi I don’t know the reason, but my board’s ld2 and ld8 leds are blinking, and the program says No STLink detection, even if I connect it to the usb port, what can be its reason? How can I fix it?

Hi,
did it work before ?
"Happened" something , like a short, connect voltage to some pins ...etc ?

The user manual describes the behavior of the various LEDs.
LD8 is overcurrent and indicates a hardware issue if nothing else is connected.
LD2 is 3.3V and should be constant. If it's blinking, you have issues.
Probably the hardware has been damaged in some way, possibly due to an overvoltage condition.

So check voltage on board , 3v3 ?
Is something getting warm/hot ? cpu ?
