Installing the DKU generally takes care of ensuring that your AJA device's firmware is the correct one to run Flame Family applications.
In some cases (eg. replacing a device, or as requested by our support team when investigating issues), it might be necessary to update the driver manually.
In order to do so, do the following, as root:
cd /opt/Autodesk/DKU/current/Utils/AJA_firmwareUpdate
./AJAfw_updateThen follow the on-screen prompts.
This utility will verify the current device's firmware, and replace it with the proper one if necessary.
