This machine configuration is for the Raspberry Pi 2B V1.2 (64-bit). Note: Raspberry Pi 2 Model B V1.2[1] switched from BCM2836[2] (V1.0, V1.1) to BCM2837[3] that is 64-bit CPU used in Raspberry Pi 3 Model B. BCM2836[2] The Broadcom chip used in the Raspberry Pi 2 Model B. The underlying architecture in BCM2836 is identical to BCM2835. The only significant difference is the removal of the ARM1176JZF-S processor and replacement with a quad-core Cortex-A7 cluster. BCM2837[3] This is the Broadcom chip used in the Raspberry Pi 3 Model B, later models of the Raspberry Pi 2 Model B, and the Raspberry Pi Compute Module 3. The underlying architecture of the BCM2837 is identical to the BCM2836. The only significant difference is the replacement of the ARMv7 quad core cluster with a quad-core ARM Cortex A53 (ARMv8) cluster. The ARM cores run at 1.2GHz, making the device about 50% faster than the Raspberry Pi 2. The VideoCore IV runs at 400MHz.

Description
This is the general hardware specific BSP overlay for the RaspberryPi device.
More information can be found at: http://www.raspberrypi.org/ (Official Site)
The core BSP part of meta-raspberrypi should work with different OpenEmbedded/Yocto distributions and layer stacks, such as:
- Distro-less (only with OE-Core).
- Yoe Disto (Video and Camera Products).
- Yocto/Poky (main focus of testing).
Yocto Project Compatible Layer
This layer is officially approved as part of the Yocto Project Compatible Layers Program. You can find details of that on the official Yocto Project
website.
Dependencies
This layer depends on:
- URI: git://git.yoctoproject.org/poky
- branch: master
- revision: HEAD
Quick Start
- source poky/oe-init-build-env rpi-build
- Add this layer to bblayers.conf and the dependencies above
- Set MACHINE in local.conf to one of the supported boards
- bitbake core-image-base
- Use bmaptool to copy the generated .wic.bz2 file to the SD card
- Boot your RPI
Quick Start with kas
- Install kas build tool from PyPi (sudo pip3 install kas)
- Set the
machine:in kas-poky-rpi.yml to one of the supported boards (see conf/machine/*.conf) - kas build meta-raspberrypi/kas-poky-rpi.yml
- Use bmaptool to copy the generated .wic.bz2 file to the SD card
- Boot your RPI
To adjust the build configuration with specific options (I2C, SPI, ...), simply add a section as follows:
local_conf_header:
rpi-specific: |
ENABLE_I2C = "1"
RPI_EXTRA_CONFIG = "dtoverlay=disable-bt"
To configure the machine, you have to update the machine variable.
And the same for the distro.
For further information, you can read more at https://kas.readthedocs.io/en/latest/index.html
Contributing
You can send patches using the GitHub pull request process or/and through the Yocto mailing list. Refer to the documentation for more information.
