MIMX8MP MIPI-CSI2 Custom Camera Capture in non-continuous clock mode.

Hi!
After successfully launching the camera with continuous clock in this topic, I continued to connect another camera. 
I can't get frames.

Camera parameters: 2 lanes mipi, pixel clock - 32.5MHz, width - 1280, height - 1024, fps 20. 

I can't understand what I'm doing wrong. Clock waveform attached.

 

camera_0: camera_0_mipi@3e {
	compatible = "camera_0";
	reg = <0x3e>;
	pinctrl-names = "default";
	pinctrl-0 = <&pinctrl_csi0_rst>, <&pinctrl_csi0_pwn>;
	csi_id = <0>;
	reset-gpios = <&gpio3 19 GPIO_ACTIVE_LOW>;
	enable-gpios = <&gpio3 20 GPIO_ACTIVE_HIGH>;
	mipi_csi;
	status = "okay";

	port {
		camera_mipi_0_ep: endpoint {
			bus-type = <4>;
			data-lanes = <1 2>;
			clock-lanes = <0>;
                        clock-noncontinuous;
			remote-endpoint = <&mipi_csi0_ep>;
		};
	};
};

&mipi_csi_0 {
	#address-cells = <1>;
	#size-cells = <0>;
	status = "okay";
	port@0 {
		reg = <0>;
		mipi_csi0_ep: endpoint {
			remote-endpoint = <&camera_mipi_0_ep>;
			data-lanes = <2>;
			csis-hs-settle = <13>;
			csis-clk-settle=<2>;
			csis-wclk;
		};
	};
	
};

&mipi_csi_1 {
	#address-cells = <1>;
	#size-cells = <0>;
	status = "disabled";
};

&cameradev {
	status = "okay";
};

&isi_0 {
	status = "okay";

	cap_device {
		status = "okay";
	};

//	m2m_device {
//		status = "okay";
//	};
};

&isi_1 {
	status = "disabled";

	cap_device {
		status = "disabled";
	};
};

&isp_0 {
    status = "disabled";
};

&isp_1 {
	status = "disabled";
};

&dewarp_0 {
    status = "disabled";
};

It turns out that the processor does not see the data at all? Why can this be so?

Hello,

 

Are you using the MX8Mplus EVK? you have a device tree in linux BSP that support two cameras MIPI-CSI.

Hello,

I'm using cpu your partner Forlinx FETMX8MP-C. with a kernel version 5.4.70.

I haven't problem problem running two cameras at the same time (4 lanes, continuous clock mode, 1920x1080@30, 148.5MHz pixel clock). 

I have a problem connecting a specific camera (2 lanes mipi, pixel clock - 32.5MHz, 1280х1024@20). It issues a clock only at the moment of frame transfer. Clock waveform attached in topic start.

Thank You!
