IMX378 Camera Sensor integration with Android

I am trying to make working IMX378 Camera on Android.

I have implemented initial version of v4l2 driver, based on existing IMX214.
Updated DTS kernel/arch/arm64/boot/dts/rockchip/rk3399-khadas-edge-android.dts for sensor

	imx378f: imx378f@1a {
       status = "okay";

       compatible = "sony,imx378";
       reg = <0x1a>;
       clocks = <&cru SCLK_CIF_OUT>;
       clock-names = "xvclk";
       /* avdd-supply = <>; */
       /* dvdd-supply = <>; */
       /* dovdd-supply = <>; */
       /* reset-gpios = <>; */
       pwdn-gpios = <&gpio2 5 GPIO_ACTIVE_HIGH>;
       reset-gpios = <&gpio2 12 GPIO_ACTIVE_HIGH>;
       pinctrl-names = "rockchip,camera_default";
       pinctrl-0 = <&cif_clkout>;
       rockchip,camera-module-index = <0>;
       rockchip,camera-module-facing = "back";
       rockchip,camera-module-name = "A12N02A-202";
       rockchip,camera-module-lens-name = "LENS";
       port {
           ucam_out0: endpoint {
                    remote-endpoint = <&mipi_in_ucam0>;
                    data-lanes = <1 2 3 4>;
               };
           };
  };	

Created file hardware/rockchip/camera/etc/camera/rkisp1/imx378_A12N02A-202_LENS.xml and just copy-pasted content from hardware/rockchip/camera/etc/camera/rkisp1/imx214_YG9626-S600Y7-C_LG-50013A7.xml, then replaced resolution parameters.

Updated file hardware/rockchip/camera/etc/camera/camera3_profiles_rk3399.xml by copy-pasing of imx214 section and resolution corrections.

dmesg logs contains information from imx378 driver, that successfully mapped and initialized.
When I am trying to launch standard Camera2 App it seems that stream from camera started, but camera app is crashed with timeout error and dmesg receive a lot of logs with error rkisp1: MIPI mis error: 0x00000002.

Is there any documentation how to write proper parameters for rkisp driver and camera engine?
What is the error type 0x0000002 means?
Is any way to “debug” MIPI data?

Replacing an IQ directly with another IQ may cause it to not work properly. You can modify it like this to confirm whether the driver is correct first?


SENSOR_TYPE_RAW ==》SENSOR_TYPE_SOC

After this modification, it will not go through the ISP channel conversion of the upper layer. If your driver and DTS configuration are OK, there will be an image.
