1 #!/bin/bash 2 # 3 # Copyright 2016 Google Inc. All Rights Reserved. 4 # 5 # This is a generic ChromeOS package/image test setup script. It is meant to 6 # be used for either the object file or package bisection tools. This script 7 # does one of the following depending on what ${BISECT_MODE} is set to: 8 # 9 # 1) ${BISECT_MODE} is PACKAGE_MODE: 10 # build_image is called and generates a new ChromeOS image using whatever 11 # packages are currently in the build tree. This image is then pushed to the 12 # remote machine using flash over ethernet (or usb flash if ethernet flash 13 # fails). 14 # 15 # 2) ${BISECT_MODE} is OBJECT_MODE: 16 # emerge is called for ${BISECT_PACKAGE} and generates a build for said 17 # package. This package is then deployed to the remote machine and the machine 18 # is rebooted. If deploying fails then a new ChromeOS image is built from 19 # scratch and pushed to the machine like in PACKAGE_MODE. 20 # 21 # This script is intended to be used by binary_search_state.py, as 22 # part of the binary search triage on ChromeOS objects and packages. It should 23 # return '0' if the setup succeeds; and '1' if the setup fails (the image 24 # could not build or be flashed). 25 # 26 27 export PYTHONUNBUFFERED=1 28 29 source common/common.sh 30 31 usb_flash() 32 { 33 echo 34 echo "Insert a usb stick into the current machine" 35 echo "Note: The cros flash will take time and doesn't give much output." 36 echo " Be patient.
