Unable to connect to ST link (Detection Fail)

[SMang.1]

I'm trying to connect the MP157c-DK2 board in Engineering board. The st link is connected on the CN11 connector.

On the st link utility it says detection failed and does not recognize the device.

​Hi @SMang.1​ 

STLink Utility is a deprecated tool which does not support STM32MP1.

STM32MP1 can be program with STM32CubeProgrammer using USB ( not ST-LINK)

For Engineering mode please use STM32CubeiDE.

Please have a look to :

Thanks for the reply.

Can you also let me know something about the IAR workbench support for the M4 core for downloading and debugging the code.

Hi @SMang.1​ ,

Yes IAR support STM32MP1 device.

We already deliver few exemples of application project for IAR/EWARM in Cube Firmware package.

For sure engineering mode is supported.

For production mode I suspect you need to manage to start Linux and load M4 firmware prior to attach with IAR.

I don't find any useful resource for usage of IAR on MP1 sorry.

Maybe check your STLink FW version (e.g. using STM32_Programmer_CLI.exe -l) and check with IAR.
