[shravan201]

Hello,

I am using iMX7D based custom board.

using fsl-yocto-L4.1.15 BSP. I have builded the images for fsl-image-gui.

unit test for ov5640 also working mx6s_v4l2_capture, but no proper color image.

how to capture image ..

Please can you share full test cases for camera ov5640 with imx7d.

Thanks,

Shravan.

Hello shravan,

   i.MX7D linux BSP support OV5640, See below , please!

...

&mipi_csi {
    clock-frequency = <240000000>;
    status = "okay";
    port {
        mipi_sensor_ep: endpoint1 {
            remote-endpoint = <&ov5640_mipi_ep>;
            data-lanes = <2>;
            csis-hs-settle = <13>;
            csis-clk-settle = <2>;
            csis-wclk;
        };

        csi_mipi_ep: endpoint2 {
            remote-endpoint = <&csi_ep>;
        };
    };
};

...

So for the issue you encountered, software should be no problem, please check if hardware connections is correct! For example, check if D0_P/D0_N & D1_N/D1_P are reversed.

Have a great day,

Hello Weidong,

I have already done these changes in dts file and my camera detecting properly..

I have cross verified the hardware connections also.

Only i need user space command to capture the image from camera.

Can you please share the command or tool to test the camera used by NXP BSP fsl-yocto-L4.1.15

Thanks,
Shravan.
