Bootstrap utilities for Raspberry Pi

General Info

Co-creators

  • Eben Upton
  • Peter Lomas

Hardware

  • SOC: Broadcom BCM2835 (CPU + GPU + SDRAM)
  • CPU: 700 MHz ARM11 ARM1176JZF-S core (ARMv6 architecture, VFP)
  • GPU: Broadcom VideoCore IV,OpenGL ES 2.0,OpenVG 1080p30 H.264 high-profile encode/decode
  • SDRAM: 256MiB
  • Video: Composite RCA and HDMI (not at the same time)
  • Audio: outputs: 3.5mm jack TRS, HDMI
  • USB 2.0 ports: 2 (via integrated USB hub)
  • Storage: SD / MMC / SDIO card slot
  • Network: LAN9512 10/100 wired Ethernet RJ45
  • Peripherals: 8 GPIO, SPI, I2C, I2S, UAR, DSI interface, CSI-2 interface, ARM JTAG
  • Power: 700mA, (3.5 Watt) 5V via Micro USB or GPIO header
  • Test Points: TP1 and TP2 giving access to +5V and GND respectively
  • 5 Status LEDs: D5(Green), D6(Red), D7(Green), D8(Green), D9(Yellow)
  • Size: 85.60mm x 53.98mm x 25mm
  • Weight: 40g
  • PCB: 6 layers

Disk layout & partitions

  • /dev/sdc1 /dev/mmcblk0p1 FAT32(LBA)
  • /dev/sdc2 /dev/mmcblk0p2 Linux
  • /dev/sdc3 /dev/mmcblk0p3 swap?

Boot partition files

  • bootcode.bin : 2nd stage bootloader, starts with SDRAM disabled
  • loader.bin : 3rd stage bootloader, starts with SDRAM enabled
  • start.elf: The GPU binary firmware image, provided by the foundation.
  • kernel.img: The OS kernel to load on the ARM processor. Normally this is Linux - see instructions for compiling a kernel.
  • cmdline.txt: Parameters passed to the kernel on boot.

Optional files

  • config.txt: A configuration file read by the GPU. Use this to override set the video mode, alter system clock speeds, voltages, etc.
  • vlls directory: Additional GPU code, e.g. extra codecs. Not present in the initial release.

Additional files supplied by the foundation

  • kernel_emergency.img : kernel with busybox rootfs. You can use this to repair the main linux partition using e2fsck if the linux partition gets corrupted.
  • arm128_start.elf : 128M ARM, 128M GPU split (use this for heavy 3D work, possibly also required for some video decoding)
  • arm192_start.elf : 192M ARM, 64M GPU split (this is the default)
  • arm224_start.elf : 224M ARM, 32M GPU split (use this for Linux only with no 3D or video processing. Its enough for the 1080p framebuffer, but not much else)

Bootstrapping Debian

Emulation

Launch QEMU with the SD image:

./emu-arm.sh single
./emu-arm.sh multi

Post-config

Run thin on the target device:

mount -oremount,rw /dev/sda2 /
mount /proc

/debootstrap/debootstrap --second-stage
dpkg --configure -a

passwd

aptitude update && aptitude dist-upgrade
aptitude install -f
aptitude clean && aptitude autoclean

sudo dpkg --get-selections '*'

vim /etc/inittab
    #Spawn a getty on Raspberry Pi serial line
    T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100

dpkg-reconfigure locales
dpkg-reconfigure tzdata
dpkg-reconfigure console-data
dpkg-reconfigure keyboard-configuration

tasksel install standard

update-alternatives --config editor
update-rc.d ssh  defaults
update-rc.d cron remove

Swap

sudo blkid
dd if=/dev/zero of=/var/swapfile bs=1024 count=524288
mkswap -L raspiswap /var/swapfile
swapon /var/swapfile
sudo vim /etc/fstab

User

adduser pi
ssh-keygen -t dsa
ssh-copy-id -i .ssh/id_dsa.pub okertanov@chromebook
sudo vim /etc/sudoers

mkdir ~/.compose-cache
