Hi,

I need to debug IPC application. I tried to do it on "hello world".

Project was successfully built with next west command:

    west build --sysbuild -p -b nrf54h20dk/nrf54h20/cpuapp -T sample.sysbuild.hello_world.nrf54h20dk_cpuapp_cpuppr . -- -DCMAKE_BUILD_TYPE=Debug

After flashing via west I was connect debugger from VSC to APP core at TX 54H20DK board:

The debugger seems to be running, but it's not working as I intended. Neither pausing nor restarting worked.

How can I debug a dual-core application on the nRF54H20?

Br, KeySoft

Try creating a sysbuild.conf , and set

SB_CONFIG_REMOTE_BOARD="nrf54h20dk/nrf54h20/cpurad"

Or, alternatively,

set this

DSB_CONFIG_REMOTE_BOARD='"nrf54h20dk/nrf54h20/cpurad"

Hi,

no, this is the error message from builder:

devzone.nordicsemi.com/.../Executing-task-nRF-Connect-General.txt

Yes, I already had the "sysbuild.cmake" file and it is the same as you posted in the link above. I need to know whether and what I have to edit / add / set to fix build problem.

Hi!

[quote user=""]I tried to test the "Hello world" sample for multicore.[/quote]

And that worked fine?

[quote user=""]set(SB_CONFIG_REMOTE_BOARD "nrf54h20dk/nrf54h20/cpurad" CACHE STRING "Remote board"), but without success.[/quote]

You also need e.g. sysbuild.cmake file
