# Copyright (C) 2014 Intel Corporation
#
# Released under the MIT license (see COPYING.MIT)
# This module adds support to testimage.bbclass to deploy images and run
# tests on a Ubiquiti Networks EdgeRouter Lite. The device must be set up
# to boot into the master image already - the easiest way to do that is as
# follows:
#
# 1. Take out the internal USB drive and plug it into your PC
# 2. Repartition the USB drive so that you have three partitions in this
# order:
# 1: vfat, labelled "boot" (it will need to be formatted with mkfs.vfat
# for this to be possible, since FAT partitions formatted under
# DOS/Windows will only support uppercase labels)
# 2: ext3 (for master image) labelled "testmaster"
# 3: ext3 (for image under test) labelled "testrootfs"
# 3. Copy the kernel to be used by the master image to the FAT partition
# (it should be named "vmlinux.64" with the factory u-boot configuration)
# 4. Install the master image onto the "testmaster" ext3 partition. If
# you do this by just extracting the contents of an image onto the
# partition, you will also likely need to create the master image marker
# file /etc/masterimage within this partition so that we can tell when
# we're booted into it that it is the master image.
# 5. Put the USB drive back into the device, and ensure the console port
# and first ethernet port are connected before powering on
#
# TEST_SERIALCONTROL_CMD will need to be set in local.conf so that we can
# interact with u-boot over the serial console port.
