Hi,

We are using the imx8mm with our custom board loaded with Android 11. Also added ov5640 camera support.

csi_mclk: csi-mclk {
        compatible = "pwm-clock";
        #clock-cells = <0>;
        clock-frequency = <20000000>;
        clock-output-names = "csi_mclk";
        pwms = <&pwm4 0 50>; /* 1 / 50 ns = 20 MHz */
};
&i2c4c {
        ov5640-mipi1@3c {
                AVDD-supply = <&reg_ldo3>;
                DOVDD-supply = <&reg_vref_1v8>;
                DVDD-supply = <&reg_vref_3v3>;
                clocks = <&csi_mclk>;
                clock-names = "xclk";
                compatible = "ovti,ov5640_mipisubdev";
                csi_id = <0>;
                mclk = <20000000>;
                mipi_csi;
                pinctrl-names = "default";
                pinctrl-0 = <&pinctrl_i2c4_ov5640_mipi>;
                powerdown-gpios = GP_OV5640_MIPI_POWER_DOWN;
                reg = <0x3c>;
                reset-gpios = GP_OV5640_MIPI_RESET;
                status = "okay";

                port {
                        ov5640_mipi1_ep: endpoint {
                                remote-endpoint = <&mipi1_ov5640_ep>;
                        };
                };
        };
};
&mipi_csi_1 {
    #address-cells = <1>;
    #size-cells = <0>;
    status = "okay";
    port {
        mipi1_ov5640_ep: endpoint@1 {
            remote-endpoint = <&ov5640_mipi1_ep>;
            data-lanes = <2>;
            csis-hs-settle = <13>;
            csis-clk-settle = <2>;
            csis-wclk;
        };

        csi1_mipi_ep: endpoint@2 {
            remote-endpoint = <&csi1_ep>;
        };
    };
};
&csi1_bridge {
    fsl,mipi-mode;
    status = "okay";

    port {
        csi1_ep: endpoint {
            remote-endpoint = <&csi1_mipi_ep>;
        };
    };
};



We are facing an issue while capturing a 5mp image with ov5640. We have observed a delay of 1s between the time the capture button clicked vs the image capture happened. Hence the frames that we got are different from what we wanted.

But when we change the capture options to .3mp this delay is not seen.
What could be the cause of this issue?

Thanks,

Hi @ashikp6 

I hope you are doing well.
 
Please tell us about the application you have used to capture images and the steps you have followed.
 
Please try using Gstreamer Pipeline (gst-launch-1.0) to capture an image to discard any hardware or driver-related issues .
 
Thanks & Regards

Hi @Dhruvit 

Made the following changes,

csi_mclk: csi-mclk {
        compatible = "pwm-clock";
        #clock-cells = <0>;
        clock-frequency = <24000000>;
        clock-output-names = "csi_mclk";
        pwms = <&pwm4 0 42>;
...
ov5640-mipi1@3c {
                AVDD-supply = <&reg_ldo3>;
                DOVDD-supply = <&reg_vref_1v8>;
                DVDD-supply = <&reg_vref_3v3>;
                clocks = <&csi_mclk>;
                clock-names = "xclk";
                compatible = "ovti,ov5640_mipisubdev";
                csi_id = <0>;
                mclk = <24000000>;
...


Still observing a delay of 1.5 seconds in capture. same issue is not observed if i capture with 0.9mp or lower
The driver being used is https://github.com/boundarydevices/linux/blob/boundary-android-11.0.0_2.2.0/drivers/media/platform/m...

Hi @ashikp6,

Please refer to the ov5640_mipi node in the "/arch/arm64/boot/dts/Freescale/imx8mm-evk.dts" as a reference to add ov5640 camera support in Android 11.

Please note that the recommended frequency for the MCLK is 24000000 Hz.

Could you please try with the above-suggested MCLK frequency?
