2.7. 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 upon power-up.

The software executes a while loop to monitor sink and source changes, and to react to the changes. The software may trigger TX reconfiguration, TX link training and start transmitting video.
