Updating Firmware

To use vr_refresh on modules connected to the communications module, you need to open a virtual port and specify the port to use. See vr_create_virtport_all.sh for more information.

Example firmware update commands for different modules (in each case, X.Y.Z should be replaced by the actual version number):

Power Module

  • vr_refresh -i 1 ~/firmware/power_converter-X.Y.Z.hex --block_size 16384

Communications Module

  • vr_refresh -i 2 ~/firmware/comms_hub-X.Y.Z.hex --block_size 16384

AHRS Module

  • vr_refresh -c vrport2 -i 3 ~/firmware/attitude_sensor-X.Y.Z.hex --block_size 16384

Thruster Module (Use the correct Node ID)

  • vr_refresh -i 5 ~/firmware/motor_controller-X.Y.Z.hex

Camera Module

  • vr_refresh -c vrport3 -i 4 ~/firmware/camera_adapter-X.Y.Z.hex --block_size 16384

LED Module (Use the correct Node ID)

  • vr_refresh -i 11 ~/firmware/led_controller-X.Y.Z.hex
