Issue with IMX219 Sensor Integration on Custom IMX8MP Board

Hardik_Prajapati — Mon, 28 Apr 2025 12:23:36 GMT

Hello,

I am currently working on integrating the IMX219 sensor with our custom IMX8MP board, using the ISP configuration.
We have ported the changes from the following repository into our custom Yocto layer: ( 6.6 sacrthgap KERNEL Version )
https://github.com/nxp-imx-support/meta-imx8mp-isp-imx219.

However, when running gst-launch-1.0 or v4l2-ctl commands, we are facing issues:

The pipeline captures the first frame with distortion but then gets stuck and does not proceed.
The image output is not proper.

Below are the details of our setup:

DTS configuration :

&i2c3 { status = "okay"; imx219: imx219@10 { compatible = "sony,imx219"; reg = <0x10>; pinctrl-names = "default"; pinctrl-0 = <&pinctrl_gpio_hog3>,<&pinctrl_gpio2>; clock-names = "xclk"; clocks = <&clk IMX8MP_CLK_IPP_DO_CLKO2>; assigned-clocks = <&clk IMX8MP_CLK_IPP_DO_CLKO2>; assigned-clock-parents = <&clk IMX8MP_CLK_24M>; assigned-clock-rates = <24000000>; mclk = <24000000>; mclk_source = <0>; csi_id=<0>; pwn-gpios = <&gpio1 1 GPIO_ACTIVE_HIGH>; port { imx219_to_mipi_csi2: endpoint { remote-endpoint = <&mipi_csi_1_in>; clock-lanes = <0>; data-lanes = <1 2>; clock-noncontinuous; link-frequencies = /bits/ 64 <456000000>; }; }; }; }; &cameradev { status = "okay"; }; &mipi_csi_0 { #address-cells = <1>; #size-cells = <0>; status = "okay"; port@0 { reg = <0>; mipi_csi_1_in: endpoint { remote-endpoint = <&imx219_to_mipi_csi2>; data-lanes = <2>; csis-hs-settle = <13>; csis-clk-settle = <2>; csis-wclk; }; }; }; &isp_0 { status = "okay"; }; &isi_0 { status = "disabled"; }; &isi_1 { status = "disabled"; }; &dewarp { status = "okay"; };

Hello,

Apparently you have to change the clock rate, I don't have your sensor at hand but iMX219 is very used with MX8MP.
