Building for Beaglebone

Building for beaglebone uses the standard build tools, with only minor adjustments to the options.

Build options

Run setup_board with the standard options:
  ./setup_board --board=beaglebone

Run build_packages with these options:
  ./build_packages --board=beaglebone --nowithtest --nowithautotest --nowithfactory

Assign a password to the 'chronos' account with the standard commands:
  ./ chronos

Run build_image with these options:
  ./build_image --board=beaglebone base

Put the image onto a micro-SD card with this command
  ./ --board=beaglebone --image=chromiumos_base_image.bin

Connecting to the serial console

  1. Plug the USB cable into an Ubuntu system.
  2. Run these commands on the Ubuntu system.
sudo modprobe ftdi_sio vendor=0x0403 product=0xa6d0
sudo screen /dev/ttyUSB1 115200
Note: In some cases, the tty device may be /dev/ttyUSB0 instead.

Booting Chrome OS on the Beaglebone

Plug the micro-SD card into the beaglebone, and apply power.  Attach to the beaglebone console, hit return, and type 'boot' at the U-Boot prompt.

Note: Power the beaglebone using the 5V barrel connector.  USB power will usually work but will fail when doing an operation with a high power draw (e.g. update_engine).
