| 18 | Given a target-files zipfile, produces an OTA package that installs |

| 20 | a full OTA is produced. |

Doug Zongker | afb32ea | 2011-09-22 10:28:04 -0700 | [diff] [blame] | 27 | -k (--package_key) <key> Key to use to sign the package (default is |
| 28 | the value of default_system_dev_certificate from the input |
| 29 | target-files's META/misc_info.txt, or |
| 30 | "build/target/product/security/testkey" if that value is not |
| 31 | specified). |
| 32 | |
| 33 | For incremental OTAs, the default value is based on the source |
| 34 | target-file, not the target build. |

| 39 | |
Tao Bao | 43078aa | 2015-04-21 14:32:35 -0700 | [diff] [blame] | 40 | --full_radio |
| 41 | When generating an incremental OTA, always include a full copy of |
| 42 | radio image. This option is only meaningful when -i is specified, |
| 43 | because a full radio is always included in a full OTA if applicable. |
| 44 | |
leozwang | aa6c1a1 | 2015-08-14 10:57:58 -0700 | [diff] [blame] | 45 | --full_bootloader |

| 47 | include a full copy of bootloader image. |

| 62 | Omit the timestamp prereq check normally included at the top of |
| 63 | the build scripts (used for developer OTA packages which |
| 64 | legitimately need to go back and forth). |
| 65 | |
Doug Zongker | 1c390a2 | 2009-05-14 19:06:36 -0700 | [diff] [blame] | 66 | -e (--extra_script) <file> |

| 73 | Generate a 'two-step' OTA package, where recovery is updated |
| 74 | first, so that any changes made to the system partition are done |
| 75 | using the new recovery (new kernel, etc.). |
| 76 | |
Doug Zongker | 26e6619 | 2014-02-20 13:22:07 -0800 | [diff] [blame] | 77 | --block |
| 78 | Generate a block-based OTA if possible. Will fall back to a |
| 79 | file-based OTA if the target_files is older and doesn't support |
| 80 | block-based OTAs. |
| 81 | |
Doug Zongker | 2556848 | 2014-03-03 10:21:27 -0800 | [diff] [blame] | 82 | -b (--binary) <file> |
| 83 | Use the given binary as the update-binary in the output package, |
