Hi all;

I have an issue with connecting an external MCU target (STM32F103ZE) with the onboard STM32F4 Discovery ST-Link.

I had this message:

''fatal error: ST-Link, failed to identify target MCU - Check hardware and interface selected''

I'm using IAR6.30 and tried to load the demo to STM3210E-EVAL with the Debugger configuration settled to ST-Link.

The STLink utility is already installed and I tried to connect to the Eval board and I have succeded. Even I have loded a binary file with it!

Connections between ST-Link and .STM3210E-EVAL:

ST-Link Target

SWCLK ---> PA14

GND ---> GND

SWDIO ---> JTMS

NRST ---> NRST

SWO ---> PB3

Does The on board ST-Link is supposed to connect only to STM32F4 devices or all STM32 devices?

thanks in advance

STM32

I found the issue:

I should configure ST-Link interface as SWD: Project options-> ST-Link -> check SWD option.
