Other Parts Discussed in Thread: TVP5150AM1, , TVP5150
Tool/software: Linux
Hi sir,
I am having AM5728 custom in which i have used TVP5150AM1 decoder at VIN3A port.The pins which i am using are mentioned below:
B7,B8,A7,A8,C9,A9,B9,A10,B11,E11,D11,C11,B10 & A26(GPIO connected to PDN).
Dts entry is mentioned below:

pinctrl-single,pins = <

status = "okay";
vin3a_1:endpoint{
slave-mode;
remote-endpoint = <&tvp5150_3_1>;
bus_width = <8>;
};
};
I am able to program and read back decoder through i2c.After loading the driver am able to get the video device in /dev directory, But i am not able to capture the frames using basic yavta command.
What could be the issue?

Todo.
