Hi @lancersky,

It looks like you need to do a git LFS pull in gecko_sdk

cd third_party/silabs/gecko_sdk
git lfs pull

If git-lfs isn't installed in your system, you should run ./script/bootstrap to install all prerequisites.

You might also run into the odd case where you have git-lfs installed in your system, but the hooks aren't installed for the submodule. If that's the case, you'll want to do the following

cd third_party/silabs/gecko_sdk
git lfs install
git lfs pull

Please let me know if this helps!

Cheers,
Mason
