If data is not being transmitted or received, check the following conditions:
• If the receive <interface_name>_vid_enable is stuck Low, the subsystem is not receiving data.
• Check that the s_axis_aclk and dphy_clk_200M inputs are connected and toggling.
• Check subsystem configuration.
• Ensure “line buffer full” condition not getting reported in subsystem Interrupt Status register.

Where,
° VBlank = Vertical Blanking (Minimum duration of one clock cycle)
° HBlank = Horizontal Blanking (Minimum duration should be greater than the time required to complete the ongoing packet on the PHY lines)
° HBP = Horizontal Back Porch (Minimum duration of one clock cycle)
° HActive = Active Pixel Data (Minimum duration of one clock cycle)
° HFP = Horizontal Front Porch (Minimum duration of one clock cycle)
Note: Once the vid_enable is asserted, it should be held high for the complete Active Pixel Data.
Note: Maximum values for the above mentioned parameters can be as per user requirement.
