The ChiliBoard is a carrier SBC for the ChiliSOM, a very small, low-power module using the TI AM335x SoC. The ChiliSOM, and therefore the ChiliBoard, is available in multiple configurations using the AM3352 at 600MHz or AM3354 at 1GHz, 128MB-512MB RAM, and up to 256MB NAND flash.

ChiliBoard features:

  • 1x USB 2.0 host port
  • 10/100Mbit Ethernet
  • MicroUSB UART console and power
  • Li-Ion battery connector, with charging and power management circuits
  • 2 user LEDs
  • Boot selection switch
  • Unpopulated JTAG port
  • 3x 40-pin expansion headers

SD Card Creation

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:
    1. For e2fsprogs < 1.43:
      mkfs.ext4 /dev/sdX1
    2. For e2fsprogs >= 1.43:
      mkfs.ext4 -O ^metadata_csum,^64bit /dev/sdX1
  5. Mount the filesystem:
    mkdir mnt
    mount /dev/sdX1 mnt
  6. Download and extract the root filesystem:
    bsdtar -xpf ArchLinuxARM-chiliboard-latest.tar.gz -C mnt
  7. Install the U-Boot bootloader:
    dd if=mnt/boot/MLO of=/dev/sdX count=1 seek=1 conv=notrunc bs=128k
    dd if=mnt/boot/u-boot.img of=/dev/sdX count=2 seek=1 conv=notrunc bs=384k
    umount mnt
  8. Insert the SD card into the ChiliBoard, connect ethernet, and apply 5V power.
  9. 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.
  10. Initialize the pacman keyring and populate the Arch Linux ARM package signing keys:
    pacman-key --init
    pacman-key --populate archlinuxarm
