Raspberry Pi 4##############- http://raspberrypi.orgHardware Information====================- ARMv8 Architecture (64-bit)- Broadcom BCM2711 (SoC)- Includes Quad ARM Cortex-A72 CPU @ 1.8 GHz- Includes VideoCore VI GPU- SD Card Storage- 1, 2, 4 or 8 GB RAM- Video Outputs- 2x HDMI Video Output via micro-HDMI- Composite Video Output- Ethernet 10/100/1000 Mbit/s- Wifi b/g/n/ac dual band 2.4/5 GHz- Bluetooth 5.0- 2x USB 2.0, 2x USB 3.0Setting up the Haiku SD card============================The Raspberry Pi SD card generally uses the MBR file system layoutbelow. Partition 1 is all that is required to boot an OS.- partition 1 – FAT32, bootable flag, type ‘ef’- partition 2 – BeFS, Haiku filesystem, type ‘eb’Boot Partition--------------Required Files~~~~~~~~~~~~~~- start4.elf: The GPU binary firmware image- fixup4.dat: Additional code for the GPU- bcm2711-rpi-4-b.dtb: FDT binary for the Raspberry Pi 4B- bcm2711-rpi-400.dtb: FDT binary for the Raspberry Pi 400- config.txt: A configuration file read by the Pi to start u-boot.bin- u-boot.bin: u-boot loader for the Pi 4- boot.scr: u-boot loader script for starting Haiku Loader- uEnv.txt: configuration file for the boot.scr script- haiku_loader.efi: Haiku LoaderNote: unlike previous Raspberry Pi models, there's no bootcode.bin on theRaspberry Pi 4 as it's replaced by a boot EEPROM.Optional Files~~~~~~~~~~~~~~- vlls directory: Additional GPU code, e.g. extra codecs.- uEnv.txt: u-boot configuration script to automate boot.Compiling Haiku and preparing SD card=====================================- Create your ARM work directory``mkdir generated.arm; cd generated.arm``- Build an ARM toolchain using``../configure --build-cross-tools arm --cross-tools-source ../../buildtools``- Build SD card image using ``jam -q -j6 @minimum-mmc``- Prepare customized SD card using the ``rune`` tool. E.g. ``rune -b rpi4 -i haiku-mmc.image /dev/mmcblk0``Booting=======1. SOC starts the boot EEPROM2. Boot EEPROM runs start4.elf3. start4.elf reads config.txt and start u-boot4. u-boot.bin starts the Haiku loader5. Haiku loader boots Haiku kernelconfig.txt Options------------------::uart_2ndstage=1enable_uart=1kernel=u-boot.binAdditional Information======================- `Latest Raspberry Pifirmware <http://github.com/raspberrypi/firmware/tree/master/boot>`__- `config.txt options <http://www.elinux.org/RPiconfig>`__
