DP TX 1.4 not adding Key Management block

Jump to solution

Hi,

   I can't seem to get Vivado to add a hdcp key management block when I enable HDCP 1.3 and 2.2 on my DP TX 1.4 block in my Vivado 2020.1 block design.

   Anybody know what I need to do to get a key management block inserted?   I tried looking in the Add IP, but nothing shows up under "hdcp".

Thanks.

Tim

@kshimizu ,

   After looking through PG224 in the link you provided I noticed the note below.

   I am not sure why you guys would not provide something we can use.

   I was able to add a key management block to my design looking at the TCL script that generated the example design.   I simply ran the TCL command below and it added it to my design.

set hdcp_keymngmt_blk_0 [ create_bd_cell -type ip -vlnv xilinx.com:ip:hdcp_keymngmt_blk:1.0 hdcp_keymngmt_blk_0 ]

Thanks.

Tim

Hello @tim_severance ,

 

I would like to make sure before coments, Have you read the PG299, PG224 and PG249?  It mentions the HDCP key.
