HI all:
Just now we use am5728's vip to captue bt1120 video(1280x720p60 video) and
We can capture the video successfully, but the video offset to right and to the downward.
We have test the sync signal, the vsync is 60HZ and the hsync is 45KHZ , the clk is 75MHZ,I think the sync work well.
below is my devicetree:
adv7842@20 {
compatible = "adi,adv7842";
reg = <0x20>;
port {
adv7842_1: endpoint {
remote-endpoint = <&vin1a>;
hsync-active = <1>;
vsync-active = <1>;
date-active = <1>;
pclk-sample = <0>;
bus-width = <16>;
};
};
};
&vip1 {
status = "okay";
};
&vin1a {
status = "okay";
endpoint {
slave-mode;
remote-endpoint = <&adv7842_1>;
};
};
Our sdk version is 3.0 and our board is an custom board.
The video link is as below:
VGA -> adv7842(transfer to 16 bit bt1120 video) -> am5728 vin1a
We use the discrete sync signal,
Please tell me what has gone wrong!
regards
wang
