STM32H745 dual-core debugging with IAR toolchain

[Jpete.1]

Hi All!

I am working on STM32H745 dual core controller and IAR Embedded Workbench for ARM toolchain V8.40.1 for development.

I have completed all my work on individual core test and debugging with help of ST-Link V3 as debugger but unfortunately , I am unable to debug both the cores at a time (with separate IDE instances for each core similar to ).

Followed AN5286 for debugger configuration but nothing found to be helpful, to my surprise the Application note shows two instances in IAR along with ST-Link V3:|

Could any one help me out in this!?

Thanks in advance folks!

Hi Jpete.1,

It is possible to debug two instances using IAR in the same time as long as you select the "shared mode" in both instances as explained in the AN. Also please make sure you select the correct reset mode.

Nevertheless in this case I believe there was a regression with IAR version V8.40.1 with dual core that should be fixed in their latest version 8.50.5. That's why I advice you to use their latest release version (you can also try with an older version like 8.32 if you have installed)

I Hope this help!
