14This test verifies Cr50 update works or recovery from erased nvmem.
15
16To test postinstall cr50 update script set test to "post_install" or use
17firmware_Cr50Update.post_install. To test the startup script leave the test arg
18blank
19
20The test will rollback to the oldest Cr50 image and then verify each update to
21the next newest image runs successfully. If testing post install, the test will
22update using cr50-update.sh. If testing the startup script the updates will be
23run with cr50-update.conf after reboot..
24
25The old release needs to have a version lower than the release image. The
26release image needs to have a version lower than the dev image. The dev image
27has to be newer than all of the images including the original cr50 image on
28the dut to be able to guarantee that the original state can be restored.
29
30If no_release path or old_release_path are given, the test will use
31old_release_ver and release_ver to fetch the images from gs://.
32
33If a valid path is given the version will be ignored. For example
34release_path='/tmp/cr50.bin.prod' or release_ver='0.0.23/ZZAF:ffffffff:7f00'
35could 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
37version .23 image stored in google cloud storage. The version string needs to
38contain the epoch, major, and minor versions separated by '.' and the image
39board id. The image board id is optional. The tests can be run against all
40versions since '0.0.13'.
41
42If dev_path is not specified, then the test will get the cr50 devids and
43attempt to get the debug image from gs://.
44
45After the test is complete the original Cr50 image will be reflashed onto the
46device.
47
48@param iterations: the number of iterations to run
49@param dev_path: the location of the dev image. Must be built with CR50_DEV=1
50@param release_path: the location of the release image
51@param release_ver: RW and BID version string used to fetch the image from gs
52@param old_release_path: the location of the old release image.
53@param old_release_ver: RW version string used to fetch the image from gs
54@param test: string representing the update type. use "post_install" if the test
55             should verify the cr50-update.sh post install script. Anything else
56             the test will run using the cr50-update.conf startup script.
