meta-raspberrypi
Yocto BSP layer for the Raspberry Pi boards - http://www.raspberrypi.org/.
Quick links
- Git repository web frontend: https://github.com/agherzan/meta-raspberrypi
- Mailing list (yocto mailing list): yocto@yoctoproject.org
- Issues management (Github Issues): https://github.com/agherzan/meta-raspberrypi/issues
- Documentation: http://meta-raspberrypi.readthedocs.io/en/latest/
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).
- Angstrom.
- Yocto/Poky (main focus of testing).
Dependencies
This layer depends on:
-
URI: git://git.yoctoproject.org/poky
- branch: master
- revision: HEAD
-
URI: git://git.openembedded.org/meta-openembedded
- layers: meta-oe, meta-multimedia, meta-networking, meta-python
- 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
- dd to a SD card the generated sdimg file (use xzcat if rpi-sdimg.xz is used)
- Boot your RPI.
