cross-compile chip-tool for raspberry Pi

[jjm202]

Has anyone been able to cross-compile CHIP-tool for a Raspberry Pi using Ubuntu? If so, can you kindly share the steps needed.

Thanks

See Matter over Thread: Configuring Border Router and controller on one device.

Specifically, we have compiled CHIP-tool in our releases at https://github.com/nrfconnect/sdk-connectedhomeip/releases/tag/v2.3.0.

Thanks for the reply. It would be nice to pull in any changes to the repo and rebuild locally, then push the changes over to the Pi. Are you familiar with anything that allows to specify the target via something like:

$ ./scripts/examples/gn_build_example.sh examples/chip-tool out/standalone

As an alternative, building CHIP-Tool on a Ubuntu ARM64 docker image and copying it to the Pi will work (https://hub.docker.com/r/arm64v8/ubuntu/)

I'm still curious if there's a way to cross-compile using the normal build steps by setting up Pi-specific arguments.

Ah, I think I understand what you are looking for.

I suggest that you create an issue at https://github.com/project-chip/connectedhomeip to ask for this, as the solution you are asking for is specific to Connectedhomeip and not Nordic, I think.
