Update stages
When firmware updates, it runs through these stages:
| Update stage | Description |
|---|---|
| Connecting | Connecting to the hub |
| Initialising | The update is initialising |
| Erasing | Erasing current firmware |
| Updating | New firmware is being installed |
| Verifying | Checking that firmware installed correctly |
| Complete | The update has completed |
| Skipped | Firmware update has been skipped on this hub |
Bootloader
The bootloader is separate firmware that allows the hub to load and update firmware. It is loaded during manufacturing and cannot be changed.
You can view bootloader version through Cambrionix Connect or by sending the id command through the CLI.
Errors
If an update fails, the updater reports the reason in the terminal.
If a hub is left in bootloader mode, run another firmware update to recover it.
Example error:
COM7: PP15S (000000) Firmware update failed. Device may now be unusable,
and may need re-flashing. caused by Device is not
responding
Daisy-chained hubs
Updating daisy-chained hubs simultaneously may fail (or appear to fail) because the tool can lose connection to downstream hubs while a parent hub reboots.
If you get Device is not responding, rerun the tool (without --force) to verify final state.
