4.3.3.1. Store plain HDCP production keys in the FPGA (Support HDCP Key Management = 0)

After generating the design, edit the HDCP key memory files to include your production keys.

To include the production keys, follow these steps.

  1. Locate the following key memory files in the <project directory>/rtl/hdcp/ directory:
    • hdcp2x_tx_kmem.v
    • hdcp2x_rx_kmem.v
    • hdcp1x_tx_kmem.v
    • hdcp1x_rx_kmem.v
  2. Open the hdcp2x_rx_kmem.v file and locate the predefined facsimile key R1 for Receiver Public Certificate and RX Private Key and Global Constant as shown in the examples below.

  3. Locate the placeholder for the production keys and replace with your own production keys in their respective wire array in big endian format.

  4. Repeat Step 3 for all other key memory files. When you have finished including your production keys in all the key memory files, ensure that the USE_FACSIMILE parameter is set to 0 at the design example top level file (a10_hdmi2_demo.v )
