3.9.1. Supporting Additional Video Resolutions

To support additional video resolutions, follow these steps:

  1. Modify the cvi_res_switch function in main.c software file to configure AXI2CV video mode bank to the desired resolution.
  2. For RX-TX restransmit design with video frame buffer:
    1. Modify the calc_frl_txclk function in the main software to add the correct TX video clock frequency configuration.
    2. Add the desired TV video clock frequency setting in set_txclk_freq function.
  3. Rebuild the software
    1. Open nios2 terminal.
    2. Change directory to /software/hdmi21_demo_app.
    3. Run <cmd>make</cmd>.
