Hi Ahmad, Thanks for your response.
We prepared images for the platform-rpi and platform-v7a using Distrokit "next" branch, as you mentioned it's having support of RPi for 32-bit. When prepared image is loaded into SD card and powered Raspberry Pi 4B, we are getting error "start_cd.elf: is not compatible". Is there any configuration needs to update? Or anything else needs to do?

The DistroKit "next" branch supports Raspberry Pi 4 in 32-bit mode. The changes are not yet in "master". The resulting image can be installed on Rasperry Pi 2, 3, CM3 and 4. Keep in mind that I did not test rpi4 support on a CM4.

If you are willing to help, adding support for Raspberry Pi 3 and 4 64-bit to DistroKit platform-v8a should be quite straight-forward. All components built by platform-v7a for Raspberry Pi can be configured for 64-bit (bootloader, kernel, rootfs, rpi firmware), but some integration into DistroKit is still required: - Add a new barebox-rpi.{make,in} rule to platform-v8a, which collects the same files as barebox-rpi2.make in platform-v7a. platform-v7a has barebox-common, but we don't have that for platform-v8a, so either add it or add it as a standalone rule - copy the barebox-rpi3.config to platform-v8a and change it to have CONFIG_64BIT=y - configure the kernel to enable all the Raspberry Pi 4 related drivers - Have DistroKit build the Raspberry Pi 4 device trees and generate bootspec entries using them - ensure config.txt has arm_64bit=1 - Add image recipes that pull in the firmware, bootloader and rootfs When done correctly, you will end up with a rpi.hdimg that can be booted from SD on either Rpi3 or Rpi4.
