The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It’s a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video.
The Raspberry Pi measures 85.60mm x 53.98mm x 17mm, with a little overlap for the SD card and connectors which project over the edges. The SoC is a Broadcom BCM2835. This contains an ARM1176JZFS with floating point running at 700Mhz, and a Videocore 4 GPU. The GPU is capable of BluRay quality playback, using H.264 at 40MBits/s.
SD Card Creation
Replace sdX in the following instructions with the device name for the SD card as it appears on your computer.
- Start fdisk to partition the SD card:
- At the fdisk prompt, delete old partitions and create a new one:
- Type o. This will clear out any partitions on the drive.
- Type p to list partitions. There should be no partitions left.
- Type n, then p for primary, 1 for the first partition on the drive, press ENTER to accept the default first sector, then type +100M for the last sector.
- Type t, then c to set the first partition to type W95 FAT32 (LBA).
- Type n, then p for primary, 2 for the second partition on the drive, and then press ENTER twice to accept the default first and last sector.
- Write the partition table and exit by typing w.
- Create and mount the FAT filesystem:
mkfs.vfat /dev/sdX1 mkdir boot mount /dev/sdX1 boot
- Create and mount the ext4 filesystem:
mkfs.ext4 /dev/sdX2 mkdir root mount /dev/sdX2 root
- Download and extract the root filesystem (as root, not via sudo):
wget http://archlinuxarm.org/os/ArchLinuxARM-rpi-latest.tar.gz bsdtar -xpf ArchLinuxARM-rpi-latest.tar.gz -C root sync
- Move boot files to the first partition:
mv root/boot/* boot
- Unmount the two partitions:
umount boot root
- Insert the SD card into the Raspberry Pi, connect ethernet, and apply 5V power.
- Use the serial console or SSH to the IP address given to the board by your router.
- Login as the default user alarm with the password alarm.
- The default root password is root.
