OV5640 camera on i.MX93 can not work on some resolution

[wenxue_guo]

Hi,

I'm debugging our OV5640 camera module on our new i.MX93 board with BSP version LF-6.1.22-2.0.0, it works fine on our some other boards based on i.MX8MN, i.MX8MM, i.MX8MQ, i.MX8ULP.

Refer to this post About settings to operate ov5640 camera on i.MX93EVK, it works on resolutions 1920x1080, 640x480, 320x240..., but can not work on 2592x1944, 1280x720, 1024x768, 720x480. Attachment is the capture images with those resolutions.

        Size: Discrete 2592x1944

Below is our DTS configuration for MIPI-CSI and image sensor.

        compatible = "ovti,ov5640";
        reg = <0x3c>;
        clocks = <&cam_xtal>;
        clock-names = "xclk";
        powerdown-gpios = <&ioexpander1 6 GPIO_ACTIVE_LOW>;
        reset-gpios = <&ioexpander1 7 GPIO_ACTIVE_LOW>;
        status = "okay";

        port {
            ov5640_mipi_ep: endpoint {
                remote-endpoint = <&mipi_csi_ep>;
                data-lanes = <2>;
                cfg-clk-range = <28>;
                hs-clk-range = <0x16>;
            };
        };
    };
};

&epxp {
    status = "okay";
};

&media_blk_ctrl {
    status = "okay";
};

&cameradev {
    status = "okay";
};

&isi_0 {
    status = "okay";

    cap_device {
        status = "okay";
    };
};

&mipi_csi {
    #address-cells = <1>;
    #size-cells = <0>;
    status = "okay";

    port@0 {
        reg = <0>;
        mipi_csi_ep: endpoint {
            remote-endpoint = <&ov5640_mipi_ep>;
            data-lanes = <2>;
            cfg-clk-range = <28>;
            hs-clk-range = <0x16>;
            bus-type = <4>;
        };
    };
};

Can anyone give us some guide to support all those resolutions ? Thanks in advanced!

Is this problem solved? I'm facing same problem with same environment.

[deepakbeniya]

Same error I am getting in Android 11 , imx8mm 
Camera - OV5640 MIPI-CSI
Display - 6 Inch MIPI-DSI 

How to solve this ?
@joanxie please post the solution here.That will be usefull for others also.

what command do you use to capture these picture? what do you get when you use command " media-ctl -p“

Hi @joanxie 

Thanks for your reply! Below is the "media-ctl -p"  command output:

And I use "gst-launch-1.0"  command  to capture images, and below is my capture shell script.

#!/bin/bash

cd $WORK_PATH

rm -f ${IMG_PRFIX}*.jpg

for ((i = 0; i < nums; i++)); do
    w=${width[i]}
    h=${height[i]}

    echo ""
