The Raspberry firmware prepares the FDT blob in memory at an address that depends on both the memory size and the blob size. For details see description in the patch itself. The patch is not yet upstream, but has already been submitted by the original author: https://lore.kernel.org/all/20210512123945.25649-1-m.salvini@koansoftware.com/ For me, the described problem occurs in conjunction with RAUC, which uses the following U-Boot script: https://github.com/rauc/meta-rauc-community/blob/master/meta-rauc-raspberrypi/recipes-bsp/rpi-u-boot-scr/files/boot.cmd.in As soon as I add an overlay the fdt_addr changes and the system does not boot anymore.

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).
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)
- 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=pi3-disable-bt"
To configure the machine, you have to update the machine variable.
And the same for the distro.
