Raspberry Pi############- http://raspberrypi.orgHardware Information====================- ARMv6 Architecture- Broadcom BCM2835 (SoC)- Includes ARM1176JZF-S CPU @ 700 MHz- Includes VideoCore IV GPU- SD Card Storage- 256 or 512 MB RAM (depending on revision)- Video Outputs- HDMI Video Output- Composite Video Output- EthernetSetting 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 ‘c’- partition 2 – BeFS, Haiku filesystem, type ‘eb’Boot Partition--------------Required Files~~~~~~~~~~~~~~- bootcode.bin : 2nd stage bootloader- start.elf: The GPU binary firmware image- config.txt: A configuration file read by the Pi to start u-boot.bin- u-boot.bin: u-boot loader for the Pi 2- bcm2835-rpi-b.dtb: FDT binary for the Raspberry Pi 2- haiku_loader_linux.ub: Haiku Loader- haiku-floppyboot.tgz.ub: Compressed initial ram image with HaikukernelOptional Files~~~~~~~~~~~~~~- vlls directory: Additional GPU code, e.g. extra codecs.- uEnv.txt: u-boot configuration script to automate boot.Compiling=========- Create your ARM work directory``mkdir generated.arm; cd generated.arm``- Build an ARM toolchain using``../configure --build-cross-tools arm ../../buildtools --target-board=rpi1``- Build our loader using ``jam -q haiku_loader_linux.ub``- Build our initial ram disk using ``jam -q haiku-floppyboot.tgz.ub``Booting=======1. SOC finds bootcode.bin2. bootcode.bin runs start.elf3. start.elf reads config.txt and start u-boot4. u-boot.bin starts the Haiku loader5. Haiku loader boots Haiku kernelconfig.txt Options------------------::kernel=u-boot.binu-boot startup--------------These will be condensed and automated long-term via uEnv.txt :-)- ``fatload mmc 0 ${fdt_addr_r} bcm2835-rpi-b.dtb``- ``fdt addr ${fdt_addr_r}``- ``fatload mmc 0 ${ramdisk_addr_r} haiku-floppyboot.tgz.ub``- ``fatload mmc 0 ${kernel_addr_r} haiku_loader_linux.ub``- ``bootm ${kernel_addr_r} ${ramdisk_addr_r} ${fdt_addr_r}``Additional Information======================- `Latest Raspberry Pifirmware <http://github.com/raspberrypi/firmware/tree/master/boot>`__- `config.txt options <http://www.elinux.org/RPiconfig>`__
