Hello all,

 

We are evaluate STM32H745 for one of our new products. Dual core feature of STM32H745 is something we would like to use.

 

As a part of initial process, I was trying to debug both M4 and M7 cores simultaneusly.

Following AN5286,  I was able to succesfully debug both core using STM32Cube IDE.

 

But when I tried following in section 4, to use IAR workbench I got following error

What I have found is ticking multicore support in IAR gives the erro

I was able to debug individual cores if I don't enable multicore.

 

 

Any guidance is deeply appreciated.

Make sure IAR version you're using has most current drivers and DLLs for ST-LINK installed.

Check for IAR IDE patches in CubeH7 Software directory in repo or ZIP file.

Many thanks for the quick response.

 

@mƎALLEmAs mentioned in my original post, I have already followed AN5286.

 

@Tesla DeLoreanI copied all the patch files over to IAR "C:\Program Files\IAR Systems\Embedded Workbench 9.2\arm" and restarted IAR. But still getting the same error message.

The link you shared pointed to: https://www.st.com/resource/en/application_note/dm00629855-getting-started-with-projects-based-on-dualcore-stm32h7-microcontrollers-in-stm32cubeide-stmicroelectronics.pdf

Which is not the correct link :)

I'm experiencing the same issue. I'm using EWARM 9.2 to connect to the H755ZI board with the STLINK-V3SET, enabling Multicore/share mode to attempt multicore debugging, but I encounter the same problem. Have you managed to resolve this issue? If so, could you let me know how you did it?
