Configure the SWUpdate Service¶

Prerequisites

The SWUpdate service starts a real swupdate@<timestamp>.service unit over the system D-Bus, so it needs real hardware and a distribution that ships the SWUpdate tool together with systemd and D-Bus support. See the meta-tolomeo documentation for building a compatible image.

Configure the plugin¶

[plugins.swupdate]
# Directory the update package is written to.
download_dir = "/tmp/tolomeo"

# Name the package is saved under. "ota.pkg" is the default.
download_filename = "ota.pkg"

# Where the OTA state snapshot is persisted, so an interrupted update survives a restart.
checkpoint_file = "/tmp/tolomeo/ota-service.yml"

For the shared [nats] and [service] tables, see the Py ToloMEO Configure NATS guide.

Run it¶

TOLOMEO_CONFIG=./tlm_swupdate.toml tlm_swupdate
