I have stm32f334c8 and when ı want to debug a code from stm cubeide program saying:no st-link device detected. What can ı do about this?

Do you have an ST-LINK, or a board with one on it?

The STM32F334C8 is a chip, it doesn't inherently come with a debugging pod.

If you have Discovery board, make sure you can see it in Device Manager, check the cable, try another.

Okay, I have stm32f072 ı will try it ,too.

when ı try first time said this:when ı said ok and update said this:

Depending on the operating system it can take a while to load the drivers for the ST-LINK once it switches to update mode.

Do you see it in DEVICE MANAGER?

Did you get a pop-up indicating it was searching for a driver? Or does Device Manager indicate it hasn't found/associated a driver with the ST-LINK ?

Once it has a driver, click Refresh and see if it shows up in the update application.

I tried for stm32f072 and app found board. After that updated board. But stm32f334 isn't updating ı dont know why board isnT detected.
