188.8.131.52. Store encrypted HDCP production keys in the external flash memory or EEPROM (Support HDCP Key Management = 1)
When Support HDCP Key Management parameter is turned on, you hold control of HDCP production key encryption by using the key encryption software utility (KEYENC) and key programmer design that Intel provides. You must provide the HDCP production keys and a 128 bits HDCP protection key. The HDCP protection key encrypts the HDCP production key and store the key in the external flash memory (for example, EEPROM) on HDMI daughter card.
- For HDMI 2.0 FMC daughter card Revision 11, make sure the EEPROM on the daughter card is Atmel AT24CS32. There are two different sizes of EEPROM used on Bitec HDMI 2.0 FMC daughter card Revision 11.
- If you had previously used KEYENC to encrypt the HDCP production keys and turned on Support HDCP Key Management in version 21.2 or earlier, you need to re-encrypt the HDCP production keys using the KEYENC software utility and re-generate the HDCP IPs from version 21.3 onwards.
