System Recovery

system_recovery is the primary executable in the recovery system. The recovery system is a second, standalone instance of Fuchsia that runs on devices to recover the primary Fuchsia system when the primary Fuchsia system is inoperative.

Building the recovery image

You can build the recovery image using the following command:

$ fx build build/images/recovery

This command builds several recovery-*.zbi files in obj/build/images/recovery, which are self-contained archives of the recovery system.

Running the recovery image

After building the recovery image, you can run the image in QEMU using the following command:

$ fx run-recovery -g

The easiest way to run recovery on hardware is to netboot a device into a newly built recovery image:

$ out/default/host-tools/bootserver --board-name device-name --boot out/default/obj/build/images/recovery/recovery-eng.zbi

where device-name can be found with fx list-devices.

NB If you only have one device or have used the fx set-device command you can omit the --board-name argument.


Build the core product with recovery:

$ fx set core.x64 --with //src/recovery
$ fx build

Load the system you've just built onto your device.


Run the recovery integration test:

$ fx test -s 5 system_recovery_tests


Run the recovery integration test:
