2.9. Hardware Setup
The HDMI FRL-enabled design example is HDMI 2.1 capable and performs a loop-through demonstration for a standard HDMI video stream.
To run the hardware test, connect an HDMI-enabled device—such as a graphics card with HDMI interface—to the HDMI sink input. The design supports both HDMI 2.1 or HDMI 2.0/1.4b source and sink.
- The HDMI sink decodes the port into a standard video stream and sends it to the clock recovery core.
- The HDMI RX core decodes the video, auxiliary, and audio data to be looped back in parallel to the HDMI TX core through the DCFIFO.
- The HDMI source port of the FMC daughter card transmits the image to a monitor.
Note: If you want to use another Intel FPGA development board, you must change the device assignments and the pin assignments. The transceiver analog setting is tested for the Intel Agilex® 7 GX FPGA development kit and Bitec HDMI 2.1 daughtercard. You may modify the settings for your own board.
|cpu_resetn||Press once to perform system reset.|
|user_pb||Press once to toggle the HPD signal to the standard HDMI source.|
Press once to read the SCDC registers from the sink connected to the TX of the Bitec HDMI 2.1 FMC daughter card.
Note: To enable read, you must set DEBUG_MODE to 1 in the software.
