PandaBoard

Install to a SD card

Replace sdX in the following instructions with the device name for the SD card as it appears on your computer.

1. Zero the beginning of the SD card:

   dd if=/dev/zero of=/dev/sdX bs=1M count=8

2. Start fdisk to partition the SD card:

   fdisk /dev/sdX

3. At the fdisk prompt, delete old partitions and create a new one:
   1. Type o. This will clear out any partitions on the drive.
   2. Type p to list partitions. There should be no partitions left.
   3. Now type n, then p for primary, 1 for the first partition on the drive, 2048 for the first sector, and then press ENTER to accept the default last sector.
   4. Write the partition table and exit by typing w.
4. Create the ext4 filesystem:

   mkfs.ext4 /dev/sdX1

5. Mount the filesystem:

   mkdir mnt
   mount /dev/sdX1 mnt

6. Download and extract the root filesystem:

   wget http://os.archlinuxarm.org/os/ArchLinuxARM-armv7-latest.tar.gz
   bsdtar -xpf ArchLinuxARM-armv7-latest.tar.gz -C mnt
   sync

7. Install the U-Boot bootloader:

   wget http://os.archlinuxarm.org/os/omap/boot/pandaboard/MLO
   wget http://os.archlinuxarm.org/os/omap/boot/pandaboard/u-boot.img
   dd if=MLO of=/dev/sdX count=1 seek=1 conv=notrunc bs=128k
   dd if=u-boot.img of=/dev/sdX count=2 seek=1 conv=notrunc bs=384k
   wget http://os.archlinuxarm.org/os/omap/boot/pandaboard/boot.scr -O mnt/boot/boot.scr
   umount mnt
   sync

8. Insert the SD card into the PandaBoard, connect ethernet, and apply 5V power.
9. Use the serial console (with a null-modem adapter if needed) 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.
10. Initialize the pacman keyring and populate the Arch Linux ARM package signing keys:

    pacman-key --init
    pacman-key --populate archlinuxarm

Install the U-Boot package

1. In order to receive updates to the U-Boot bootloader, after logging into the system type:

   pacman -Sy uboot-pandaboard

2. When prompted, press y and hit enter to flash the bootloader to the SD card.

Permanent MAC address

1. Edit /boot/boot.txt
2. Append smsc95xx.macaddr to the bootargs variable, for example:

   setenv bootargs "console=ttyO2,115200n8 console=tty1 root=PARTUUID=${uuid} rw rootwait smsc95xx.macaddr=ce:1a:7d:93:2f:f9"

3. Run mkscr from within /boot to generate the boot.scr file:

   ./mkscr

4. Reboot.
