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

guffigubber — Thu, 02 Feb 2023 06:22:16 GMT

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"; };

Hello,

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

Regards

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!

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