Can share me example script to enable HDMI to MIPI CSI 4-Lane with YUV422 8bit on 576p resolution by using adv7481?
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?
