The UHD-SDI TX Subsystem is delivered with a Baremetal driver and API designed to handle all programming of the subsystem core. This driver is automatically available in the Vitis™ tool when you create from a .xsa file, which includes the UHD-SDI TX Subsystem. This Baremetal driver is also available from the Xilinx Github [Ref 19]. The example designs in Example Design showcase the use of the drivers in an application.
Information on Linux drivers can be found on the Xilinx Wiki [Ref 20].
