STM32CubeIDE shows "NO ST-LINK DETECTED."

[sanjay890]

We're using the STM32F407VET6 microcontroller. When I connect it to my Windows laptop and attempt to debug with STM32CubeIDE, it shows "NO ST-LINK DETECTED, CONNECT AND RESTART DEBUGGING." I’m unsure how to resolve this issue. The user manual states it has a built-in debugger, but CubeIDE isn’t recognizing it. We need help, as this is crucial for our final year engineering project.

What board is that? It doesn't look like a genuine ST board.

Does the board actually have an ST-Link?

If it is supposed to have an ST-Link, does Windows detect it?

Please see this for how to capture a screenshot - far better than photographing the screen!

But that doesn't seem to be true from the photo.

Perhaps they (and/or you) are confusing the internal debug features within the STM32 chip with the external hardware (eg, ST-Link) needed to access those features from tools like CubeIDE?

Please provide a link to this User Manual - and the other board details.

It looks like one of these:

So definitely not an ST board - and it has no ST-Link.

Note also that these are also not genuine ST-Links:

This board does not provide an ST-LINK, but rather has a 20-pin ARM JTAG header to which you can attach an ST-LINK,  J-LINK or U-LINK etc, that you supply.

If there is no ST-LINK your PC isn't going to find one.
