To test the startup script leave the test arg 18 blank 19 20 The test will rollback to the oldest Cr50 image and then verify each update to 21 the next newest image runs successfully. If testing post install, the test will 22 update using cr50-update.sh. If testing the startup script the updates will be 23 run with cr50-update.conf after reboot.. 24 25 The old release needs to have a version lower than the release image. The 26 release image needs to have a version lower than the dev image. The dev image 27 has to be newer than all of the images including the original cr50 image on 28 the dut to be able to guarantee that the original state can be restored. 29 30 If no_release path or old_release_path are given, the test will use 31 old_release_ver and release_ver to fetch the images from gs://. 32 33 If a valid path is given the version will be ignored. For example 34 release_path='/tmp/cr50.bin.prod' or release_ver='0.0.23/ZZAF:ffffffff:7f00' 35 could be used. The test will attempt to get the cr50 image from 36 /tmp/cr50.bin.prod first. If that doesn't exist then it will download the 37 version .23 image stored in google cloud storage. The version string needs to 38 contain the epoch, major, and minor versions separated by '.' and the image 39 board id. The image board id is optional. The tests can be run against all 40 versions since '0.0.13'. 41 42 If dev_path is not specified, then the test will get the cr50 devids and 43 attempt to get the debug image from gs://. 44 45 After the test is complete the original Cr50 image will be reflashed onto the 46 device. 47 48 @param iterations: the number of iterations to run 49 @param dev_path: the location of the dev image.
