Updating Firmware

Firmware can be found locally in the Home/firmware/ folder. The most up-to-date firmware is available from VideoRay's FTP server. You can download the firmware to the local folder by connecting to the Internet and using the following command:

• vr_pull_firmware.sh

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 are shown below. In each case, X.Y.Z should be replaced by the actual version number. Each vr_refresh command should be entered on one line. Ignore any line breaks that may appear in the vr_refresh commands displayed below.
