hi guys,
I have a problem! I am tryin' to program a STM32F407VGT microcontroller, but when I connect the programmer the st-link debugger keeps sayin' "no st-link detected" . I have installed the st-link usb driver over and over but didn't help. usin' the utility doesn't change anything as well. please help... (I'm using keil u vision 5 by the way)
Good point!
So, another thing to check: Is the STLink detected OK when it's not connected to your board?
I think it would have to be quite a gross error to actually stop the STLink working!
Note that the error "STLink not detected" is distinct from "Cannot connect to target" errors (in the ST Utility, at least):
* "STLink not detected" means that the PC cannot see the STLink at all - check in Device Manager;
* "Cannot connect to target" errors mean that the STLink can be seen, but then there's a problem connecting to the target.
Is it a genuine, standalone STLink - from ST?
Is it a genuine, embedded STLink - on a Discovery or Nucleo board?
Or is it a cheap knock-off from ebay, etc?
If it's a cheap ebay knock-off, check the target connector pinout carefully - there are some identical-looking units which have different pinouts!!
