Layer Contents¶
Supported Machines¶
raspberrypi
raspberrypi0
raspberrypi0-wifi
raspberrypi0-2w-64
raspberrypi2
raspberrypi3
raspberrypi3-64 (64 bit kernel & userspace)
raspberrypi4
raspberrypi4-64 (64 bit kernel & userspace)
raspberrypi-cm (dummy alias for raspberrypi)
raspberrypi-cm3
Note: The raspberrypi3 machines include support for Raspberry Pi 3B+.
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.
