5# This module adds support to testimage.bbclass to deploy images and run
6# tests on a BeagleBone (original "white" or Black models). The device must
7# be set up as per README.hardware and the master image should be deployed
8# onto the card so that it boots into it by default. For booting into the
9# image under test we interact with u-boot over serial, so for the
10# BeagleBone Black you will need an additional TTL serial cable since a
11# serial interface isn't automatically provided over the USB connection as
12# it is on the original BeagleBone ("white") version. The separate ext3
13# partition that will contain the image to be tested must be labelled
14# "testrootfs" so that the deployment code below can find it.
15#
16# NOTE: for the BeagleBone "white" (original version) you may need to use
17# a script which handles the serial device disappearing on power down, such
18# as scripts/contrib/serdevtry in OE-Core.
