hifiberry-adc, hifiberry-adc8x and hifiberry-dac8x cannot be selected at all - naming one in config.txt gives a card that never appears and no error to go with it. hifiberry-studio-dac8x and hifiberry-studio-dac8x-pro are left out on purpose. They were added to the kernel in https://github.com/raspberrypi/linux/commit/ba7ae2c94ff9ace5d9df63a3b0ea4a1a99f06b29 and are absent from the kernel the 6.6 recipe pins, and this list is shared by every kernel recipe the layer ships, so adding them would break a 6.6 build. Verified with PREFERRED_VERSION_linux-raspberrypi = "6.6.%": the three overlays added here compile, while adding hifiberry-studio-dac8x on top fails do_compile with "No rule to make target 'arch/arm/boot/dts/overlays/hifiberry-studio-dac8x.dtbo'".

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: https://git.openembedded.org/bitbake
- branch: master
- revision: HEAD
-
URI: https://git.openembedded.org/openembedded-core
- branch: master
- revision: HEAD
-
URI: https://git.yoctoproject.org/meta-yocto
- branch: master
- revision: HEAD
Quick Start
- source openembedded-core/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.
