| ## Multi-board Machines |
| |
| This layer generally provides support for machines that are targetting a single |
| Raspberry Pi board (or a very few subsets of them). This is so that the build |
| infrastructure can tune and tweak the configuration with the flexibility to |
| optimise for both runtime performance and disk storage. |
| |
| For usecases where compatibility of more boards is required, the layer provides |
| machines that are tagetting a wider support of Raspberry Pi boards. |
| |
| ### raspberrypi-armv7 |
| |
| This machine targets support for all the ARMv7-based Raspberry Pi boards. It |
| will pull in the firmware and deploy the kernel image and kernel modules for |
| all the relevant boards. |
| |
| ### raspberrypi-armv8 |
| |
| This machine targets support for all the ARMv8-based Raspberry Pi boards. It |
| will pull in the firmware and deploy the kernel image and kernel modules for |
| all the relevant boards. |
| |
| ## Images |
| |
| * rpi-test-image |
| * Image based on core-image-base which includes most of the packages in this |
| layer and some media samples. |
| |
| For other uses it's recommended to base images on `core-image-minimal` or |
| `core-image-base` as appropriate. |
| |
| ## WiFi and Bluetooth Firmware |
| |
| Be aware that the WiFi and Bluetooth firmware for the supported boards |
| is not available in the base version of `linux-firmware` from OE-Core |
| (poky). The files are added from Raspbian repositories in this layer's |
| bbappends to that recipe. All machines define |
| `MACHINE_EXTRA_RRECOMMENDS` to include the required wireless firmware; |
| raspberrypi3 supports 3, 3B, and 3B+ and so include multiple firmware |
| packages. |
