Hi @Fred-Blais, we agree, it's much easier to do the cross-compilation if we provide the SDK. But the problem with the SDK is that it's hard to predict what platform one is trying to compile the firmware on. We'll probably add some content to the tutorial to show how to setup the environment with the SDK. Also, we will be launching a cross-compilation service for you to upload packages to be compiled. Hopefully all of these will make it much easier for everyone who wants to create their own packages.
