3.3.5. BSP Descriptions

BSP descriptions (i.e. *.scc files) combine kernel types with hardware-specific features. The hardware-specific Metadata is typically defined independently in the BSP layer, and then aggregated with each supported kernel type.

Note

For BSPs supported by the Yocto Project, the BSP description files are located in the bsp directory of the yocto-kernel-cache repository organized under the "Yocto Linux Kernel" heading in the Yocto Project Source Repositories.

This section overviews the BSP description structure, the aggregation concepts, and presents a detailed example using a BSP supported by the Yocto Project (i.e. BeagleBone Board). For complete information on BSP layer file hierarchy, see the Yocto Project Board Support Package (BSP) Developer's Guide.
