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