| DOC = """ |
| This test verifies Cr50 can recover from erased nvmem. |
| |
| The test will update to the dev image and then rollback to the release image. |
| During the rollback Cr50 will erase nvmem. The test verifies the device boots |
| into normal mode and not recovery after nvmem has been erased. |
| |
| The release_image needs to have a version lower than the dev_image. The |
| dev_image needs to have a higher version than the release image and whatever |
| image is running on Cr50 at the start of the test to guarantee that the |
| original state can be restored. |
| |
| After the test is complete the original Cr50 image will be reflashed onto the |
| device. |

| @param dev_image: the location of the dev image. Must be built with CR50_DEV=1 |
