| # Update target device | |
| This is a subcommand of the `ffx target` command. It provides options to: | |
| - check whether the target device is up to date | |
| - request (and monitor) an update to the device | |
| - [wip] force the device to "update" to a specific system image (regardless of | |
| whether that system image is older than the current image) | |
| The code runs on the host and communicates to software running on the target | |
| Fuchsia device via FIDL through an overnet connection. | |
| ## Build | |
| To build the target update command, build ffx which statically links the update | |
| lib. E.g. | |
| ``` | |
| $ fx build src/developer/ffx | |
| ``` | |
| ## Test | |
| Run tests with | |
| ``` | |
| $ fx test ffx_update_lib_test | |
| ``` |
