Google has finally released its Fuchsia/magenta kernel of the Raspberry Pi version, the following describes how to compile and run
Ready to work, first need to have an HDMI screen, I'm here is the 800x480 HDMI screen, then the keyboard
Download Magenta code from Google src or github
Https://fuchsia.googlesource.com/magenta
In the running directory
Scripts/download-toolchain Download the tools needed, I am here because of using MacOS, so download is Darwin's tool
Then switch to working directory using
Make magenta-rpi3-arm64 compile the magenta
After the compilation is complete
CP./build-magenta-rpi3-arm64/magenta.bin <path to SD card>/kernel8.img
CP./build-magenta-rpi3-arm64/bootdata.bin <path to SD Card>/bootdata.bin
CP./kernel/target/rpi3/config.txt <path to SD card>/config.txt
CP./kernel/target/rpi3/cmdline.txt <path to SD card>/cmdline.txt
CP./KERNEL/TARGET/RPI3/BCM2710-RPI-3-B.DTB <path to SD CARD>/BCM2710-RPI-3-B.DTB
Then download it from the link below
Https://raw.githubusercontent.com/raspberrypi/firmware/7fcb39cb5b5543ca7485cd1ae9e6d908f31e40c6/boot/bootcode.bin
Https://github.com/raspberrypi/firmware/raw/390f53ed0fd79df274bdcc81d99e09fa262f03ab/boot/start.elf
and copy the Bootcode.bin and start.elf to the SD card
Finally check the SD card of the MBR BOOT partition that contains
Bootcode.bin
Bootdata.bin
Config.txt
Kernel8.img
Start.elf
Bcm2710-rpi-3-b.dtb
Cmdline.txt
These 7 files, insert SD card into Raspberry Pi 3, re-power on Raspberry Pi 3 will see the following
Has fun
