    which work bench are you using. IAR?? Select the correct target MCU in project settings.

    Also select ST link as the debugger in the debugger tab in the setting.

    I didn't ask if you were using it, I was suggesting you see if it works any better. So try it.

    Does the ST-LINK utility work?

    Is this a standard board, or something custom?

    The ST-LINK can have a hard time breaking into a system with certain things happening early in the reset process (it has to run several thousand cycles before it gains control). If it's running your code you could change the BOOTx pin states and have it run the System Loader instead.

    The U-Link (Keil) and J-Link are more robust commercial JTAG pods
