Downgrading GigaVUE Nodes

IMPORTANT: It is highly recommended to not downgrade GigaVUE nodes from higher software versions to lower software versions.

When downgrading a node from 6.0.00 or higher to lesser than 6.0.00 software version, the device can occasionally get in to in a reboot loop. Use the following procedure to exit from the reboot loop:

  1. Use the reset factory all command on the specific node that is to be downgraded to a lower version.
  2. Replace the image in the next partition with the image of the required version to be downloaded. This prevents the script file from wrongly fetching the template file from the next version.
After resetting the node, if the node gets stuck in reboot loop:
  • Modify the kernel param by pressing “ESC” key while the node boots up.
  • Press “e” to edit kernel param.
  • Modify the rw to “ro”.
