Problem with STMLink.
Are you having an issue with the com led blinking on the ST link side?
STM Link not detected through Keil or any other program that you using.
Well I have googled my way to debug this problem.
I think the interface is pretty much fool proof.
There are certain things that might cause this, but most of the times it is not the board. Just trust the board for now, and start questioning how you got into this situation ( well this is the first thought a embedded system debugger, because the Micro controller listens to what you say ). I spent crashing my head for couple of hours but my dejavu sense kind of kicked in and I was able to figure out easily. But in case if you are on road or already crossed this road, I am happy please share your story.
There might be these reasons:
1. faulty cables. - This might be one of the reasons of the failure. Chance are the USB wire worn on out or some thing like.
I would advice you to change that. Get a new cable and try that out. But before running to a friend to get one check out the next reason.
( I have swapped the cable that I used for my camera ).
2. Driver Issue. - The driver kind of gets screwed up some time.
Go to device manager and check if the USB device has loaded or not.
Re-start might work.
Or try it on a new machine.
3. Power Supply: If things gets this bad:
First thing if you are a starter change the board dont spend too much time. 8$ is not worth than your valuable time you waste around doing stuff that might not work at the end or end up frying other stuff.
(or)
If you are a serious dude and want to get the thing working there is a wikia page. I tried what ever they said, but I could not get it working.
