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