3.1.6. Agilex™ 5 HDMI RX-TX Retransmit With Integrated Transceiver Design Software Flow

In the design main software flow, the Nios V processor configures the TI redriver setting and initializes the TX and RX paths on power-up.
Figure 10. Software flow in main.c ScriptThe software executes a while loop to monitor sink and source changes, and to react to the changes. The software may trigger TX reconfiguration, and start transmitting video.
Figure 11. Initialize TX Path Flowchart
Figure 12. Initialize RX Path FlowchartAs per HDMI 2.1 specifications, software flow still checks for FRL value. For this design, the FRL value is always zero. The process directly skips to the TMDS mode.
Figure 13. TX ReconfigurationFor this design, the FRL value is always zero. The process skips TX link training and proceeds to the TMDS mode.
