I'm a beginer with IAR.

I selected the st_link for the debugger

but this error is generated :''Fatal error: ST-Link, Failed to identify target MCU - Check hardware and interface selected Session aborted! ''

I tried one of the project that are included in IAR it work fine. so the problem is not from the driver.

Do you have SWD mode selected? JTAG mode won't work.

Pay very careful attention to the settings in the project that works, and compare those with the one that fails.
