Add the relevant QB_ variables sufficient to get the QEMU raspi1ap model running with runqemu. The dwc_otg.fiq_fsm_enable setting is necessary to get USB devices (both disk and net) working. Without this, boot hangs. The initcall_blacklist=bcm2835_pm_driver_init is needed to workaround other boot issues. Seems like the PM HW emulation isn't present in the QEMU model. Adding the QB_ fields, etc to raspberrypi.conf, is adding support to raspberrypi-cm, which doesn't have an emulated board, and adding some of the wrong fields to raspberrypi0. So, remove the include and put the contents in the relevant files. Signed-off-by: Jon Mason <jon.mason@arm.com>

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.
