Can share me example script to enable HDMI to MIPI CSI 4-Lane with YUV422 8bit on 576p resolution by using adv7481?
Did you do the experiment on one of our evaluation board and observe the results that you reported?
Seems like this register is related to HDCP, referring the HDCP specification would be helpful.
Please refer this thread at (ADV7480)BCAP setting
Please also visit ADV7481 Design Support Files
720x480p60 and 720x576p50 are supported over 4 MIPI data lane in the YUV422 8-bit format. Please refer to table 81 in the hardware manual available here: ADV7481 Design Support Files
The script to use is :01-21 HDMI to MIPI TxA CSI 4-Lane - YUV422 8-Bit, Up to 600Mbps: in the ADV7481ES3C-VER.3.6c script file.
Regarding the setting for Reg 0x40 in the HDMI RX Repeater Map, please refer to the HDCP specification. Bit 6 corresponds to the REPEATER bit in the Bcaps register. When you have this bit set, are you following the requirements for an HDCP repeater as described in the HDCP specification?
