DESCRIPTION

This script is used to test public autobuilder images on remote hardware.

The script is called from a machine that is able download the images from the remote images repository and to connect to the test hardware.

test-remote-image --image-type core-image-sato --repo-link http://192.168.10.2/images --required-packages rpm psplash

Translation: Build the 'rpm' and 'pslash' packages and test a remote core-image-sato image using the http://192.168.10.2/images repository.

You can also use the '-h' option to see some help information.

import os import sys import argparse import logging import shutil from abc import ABCMeta, abstractmethod

Add path to scripts/lib in sys.path;

scripts_path = os.path.abspath(os.path.dirname(os.path.abspath(sys.argv[0]))) lib_path = scripts_path + '/lib' sys.path = sys.path + [lib_path]

import scriptpath import argparse_oe

Add meta/lib to sys.path

scriptpath.add_oe_lib_path()

import oeqa.utils.ftools as ftools from oeqa.utils.commands import runCmd, bitbake, get_bb_var

Add all lib paths relative to BBPATH to sys.path; this is used to find and import the target controllers.

for path in get_bb_var('BBPATH').split(":"): sys.path.insert(0, os.path.abspath(os.path.join(path, 'lib')))

In order to import modules that contain target controllers, we need the bitbake libraries in sys.path .

bitbakepath = scriptpath.add_bitbake_lib_path() if not bitbakepath: sys.stderr.write("Unable to find bitbake by searching parent directory of this script or PATH\n") sys.exit(1)
