Docs: Troubleshooting: Invalid Robot Firmware

The firmware logs the following error repeatedly and the status LED blinks red:

Robot firmware '<name>' invalid for this hardware...

This means the board: value in your mower_params.yaml does not match the mainboard that is actually installed. The firmware rejects the name and keeps waiting for a valid one.

Open the ROS configuration (this opens mower_params.yaml):

openmower configure ros

Set the board: value under ll: field to the board type that matches your hardware:

ll:
 board: "YardForce"

After saving, OpenMower restarts automatically and should boot with a green status LED.

Edit ~/params/custom_params.yaml:

nano ~/params/custom_params.yaml

Set the board: value under ll:, for a Universal board, use Universal-5S, Universal-7S, or Universal-8S depending on your battery:

ll:
 board: "Universal-7S"

Editing custom_params.yaml does not restart the stack automatically, so apply the change via:

openmower restart

See Universal Board Configuration for the full custom-build reference.

Valid board types

Board type	Hardware
`YardForce`	Regular YardForce board
`YardForce-V4`	YardForce board with YFR4-xESC (old Rev.4 mow motor)
`Universal-5S`	Universal board with 5S battery
`Universal-7S`	Universal board with 7S battery
`Universal-8S`	Universal board with 8S battery
`Worx`	Universal board with Worx functionality
`Lyfco-E1600`	Universal board with Lyfco-E1600 functionality
`Husq310MKII`	Husqvarna 310 MKII board

The value must match exactly (including capitalization).

The default template with all valid values lives in the OpenMowerOS repository: mower_params.yaml .
