How to solve these problems about STMf103c8t6 ST-LINK

[MarcusRay]

hello my friends!I'm trying to find a solution to this problem. I'm doing an experiment with a small light, and I encountered a problem that pops up a dialog box like this after compiling and downloading, and it has something to do with ST-link, so I hope some of my friends can solve the problem.

You're trying to do a firmware update, but the ST-Link is not in the correct mode ("DFU mode") for doing a firmware update.

 

CubeIDE cannot see any ST-Link connected to your computer.

If you've had a failed firmware update, that could explain it.

First question - do you have a genuine ST-Link?

Also, is your STM32 genuine? (if it's on a blue, black, or other coloured "Pill", it probably isn't)
