Camera sensor hi846 MIPI CSI for IMX8MM: Image issue

shixuanlin-ddcx — Wed, 23 Oct 2024 03:02:08 GMT

Dear all：

I used imx8mm board, and hi846 camera sensor. The os is yocto, my kernel branch version is lf-5.15.y and hi846 driver copy from lf-6.1.y. I also add some patches like this link #https://community.nxp.com/t5/i-MX-Graphics/gst-launch-1-0-returns-Internal-data-stream-error/m-p/1573923#M388#. But unfortunately, I still can’t get right output by v4lt-ctl or gst-launch-1.0 commands

 v4l2-ctl -d /dev/video0 --verbose --set-fmt-video=width=1632,height=1224,pixelformat=GB10 --stream-mmap --stream-count=1 --stream-to=raw10.raw

These two commands are always running, test.png and raw actually have no content.v4l2-ctl --list-formats-ext:

My dts code:

        status = "okay";

        compatible = "hynix,hi846";
        reg = <0x20>;

        reset-gpios = <&gpio3 19 GPIO_ACTIVE_HIGH>;
        shutdown-gpios = <&gpio4 10 GPIO_ACTIVE_HIGH>;
        port {
            hi846_out: endpoint {
                remote-endpoint = <&mipi1_sensor_ep>;
                data-lanes = <1 2>;
                link-frequencies = /bits/ 64
                   <80000000 200000000>;
            }; 
        };
    };
};
&mipi1_sensor_ep {
   remote-endpoint = <&hi846_out>;
   data-lanes = <1 2>;
   csis-hs-settle = <13>;
   csis-clk-settle = <0>;
   csis-wclk;
};

How should I check? I sincerely hope to get your help. Thanks!

HI @shixuanlin-ddcx

Sorry for reply late. Firstly, In our default BSP code, our i2c4 for i.mx8mm was disabled, did you enable it?

And about the dts file configuration, please refer the ov5640 on the imx8mm-evk-dtsi file

https://github.com/nxp-imx/linux-imx/blob/lf-6.6.y/arch/arm64/boot/dts/freescale/imx8mm-evk.dtsi
