ADV7511 Zedboard no-OS ref design - set resolution to 800x480

I managed to build the Vivado project & no-OS SDK application from the github repos of the ADV7511 Xilinx Evaluation Boards reference design, with Vivado 2015.2.1


After programming the bitstream, and running the no-OS application, I can see the Analog Devices / Xilinx image on my display, in both the 640x480 or 800x600 resolution setting. 'Out of the box' the no-OS project seems to support these resolutions :


enum videoResolution











unfortunately my display has a 800x480 resolution.


My questions :


  1. I'd like to have some guidance on how to modify the no-OS code to support this 800x480 resolution.
  2. Do I need to modify some parameters in the Vivado project? I.e. in the 'axi_clkgen_v1_0' or the 'axi_hdmi_tx_v1_0'
  3. Can I find more documentation on these custom IP blocks, how to use them, how to calculate the parameter values?
