4.3.3.1.4. hdcp2x_tx_kmem.v file

For hdcp2x_tx_kmem.v file:
  • To identify the correct HDCP2 TX DCP key file for hdcp2x_tx_kmem.v, make sure the first 4 bytes of the file are “0x00, 0x00, 0x00, 0x01”.
  • The keys in the DCP key files are in little-endian format.
  • Alternatively, you can apply the lc128_prod from hdcp2x_rx_kmem.v directly into hdcp2x_tx_kmem.v. The keys share the same values.
