I'll take a look tomorrow and update you here. I should be able apply a quick fix if need be

@lboue I also wanted to point out 2 things. I see you are going to the example repo and using the gn gen and ninja commands directly. This is ok. But also leaves you open to some bad configurations if you swap boards and do not clean your out folder as the args.gni created in the out for one board might not work for a different one. I believe the last of the issue you hit comes from that

I suggest using the build script. Here is an example

./scripts/examples/gn_efr32_example.sh examples/lighting-app/silabs/efr32/ out/lighting_app BRD2704A

Thanks for the advice. I tried both methods at first.
