Building multicore with sysbuild in VS Code for nRF54H20

[Peter Langer Keysoft]

Hi,

nRF54H20DK (rev. 0.9.1), SDK: v2.9.0-nRF54H20-rc2 and the same Toolchain, IDE: VSCode + nRF Connect

We need to implement a multicore application for nRF54H20. I tried to test the "Hello world" sample for multicore.

I read the "readme" file and tried to add to CMakeLists.txt "

set(SB_CONFIG_REMOTE_BOARD "nrf54h20dk/nrf54h20/cpurad" CACHE STRING "Remote board"), but without success.

How to compile this example correctly in VS Code? Do we need to make any changes in the files (like prj, CMake,...)?
Is it possible to do it only through VS Code and nRF Connect or do we have to use the "west" command directly?

Here is my tested config:

How can I use this config from README?

Thanks.

Hi!

I tried to test the "Hello world" sample for multicore.

And that worked fine?

set(SB_CONFIG_REMOTE_BOARD "nrf54h20dk/nrf54h20/cpurad" CACHE STRING "Remote board"), but without success.

You also need e.g. sysbuild.cmake file

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
