      I am now building a 1080P HDMI display project on zedbord according to the wiki ADV7511 Xilinx Evaluation Boards Reference Design [Analog Devices Wiki]

I found that Audio portion is not necessary for ADV7511 according to the answer here

So I removed the Audio IP core and DMA channel from Reference Design and disabled Audio relate code in .c files.

I am using vivado 2015.1.

After download hardware and software program, the screen display a full green. As below:



I find an explanation of HDL IP core Registers here

So I print HDL cores register value .

CLKGEN REGs are from ClockGenerator (axi_clkgen) IP core.

HDMITXCORE REGs are from HDMI Transmit (axi_hdmi_tx) IPcore.

VDMA regs are from Xilinx VDMA IP core.

  S2MM_HSIZE_STATUS= 0x00000000

  S2MM_VSIZE_STATUS= 0x00000000



It seems the VDMA is OK.

Are there something wrong with ClockGenerator (axi_clkgen)  or HDMI Transmit (axi_hdmi_tx) ?

How can I fix the problem?

Thank you very much !
