We utilize the Yocto project to generate a root file-system, Linux kernel binary, U-boot binary and toolchain (SDK).
It is recommended that you have an powerful host machine that is used for BSP builds with Yocto/OE-core. The build usually takes a few hours the first time you run it, subsequent builds take minutes (depending on what changes you have made)
We provide a manifest file that can be used together with Google repo.
Check here for further instructions on how to setup and build with Yocto/OE-core.
