Hello

I have stm32mp135f-dk board and OV6540 camera how can I connect them

[Erwan SZYMANSKI]

Hello @kagan_senkeser,
You need to change the device tree of stm32mp135f-dk board in the Linux kernel : https://github.com/STMicroelectronics/linux/blob/4c4175804a542f40c50d091cc694bb0b186728a0/arch/arm/boot/dts/stm32mp135f-dk.dts#L4

Please modify the i2c5 node :

gc2145: gc2145@3c {
		compatible = "galaxycore,gc2145";
		reg = <0x3c>;
		clocks = <&clk_ext_camera>;
		IOVDD-supply = <&scmi_v3v3_sw>;
		AVDD-supply = <&scmi_v3v3_sw>;
		DVDD-supply = <&scmi_v3v3_sw>;
		powerdown-gpios = <&mcp23017 3 (GPIO_ACTIVE_LOW | GPIO_PUSH_PULL)>;
		reset-gpios = <&mcp23017 4 (GPIO_ACTIVE_LOW | GPIO_PUSH_PULL)>;
		status = "disabled";

		port {
			gc2145_ep: endpoint {
				/*remote-endpoint = <&mipid02_0>;*/
				clock-lanes = <0>;
				data-lanes = <1 2>;
			};
		};
	};

	ov5640: camera@3c {
		compatible = "ovti,ov5640";
		reg = <0x3c>;
		clocks = <&clk_ext_camera>;
		clock-names = "xclk";
		DOVDD-supply = <&scmi_v3v3_sw>;
		status = "okay";
		powerdown-gpios = <&mcp23017 3 (GPIO_ACTIVE_LOW | GPIO_PUSH_PULL)>;
		reset-gpios = <&mcp23017 4 (GPIO_ACTIVE_LOW | GPIO_PUSH_PULL)>;

		port {
			ov5640_0: endpoint {
				remote-endpoint = <&mipid02_0>;
				clock-lanes = <0>;
				data-lanes = <1 2>;
			};
		};
	};

Do not hesitate to follow wiki information for configuration and other steps to do : https://wiki.st.com/stm32mpu/wiki/STM32MP13_V4L2_camera_overview

Kind regards,
Erwan.

Hello thank you but I mean the physical part because camera has pins. not camera cable socket like gc2145.

Hello @kagan_senkeser ,
Do you have a link or a photo of the camera you use ? 

Kind regards,
Erwan.

@kagan_senkeser ,
I do not remember having the same camera module on my side. However, I guess that the white connector in the middle can be used as CSI connector, right? 

If yes, you need to connect the camera CSI connector to CSI connector of STM32MP135F-DK board. To find the CSI connector, please refer to the user manual of the board. It is a black connector (CN1) at the bottom face of the board.

Kind regards,
Erwan.

I'm not sure is it CSI but our gc2145 cable does not fit there.

[Erwan SZYMANSKI]

@kagan_senkeser ,
Maybe you have to find the right flat cable that will fit with both connectors. However your first need to be sure that the connector on the camera is a CSI one.
Please try to get the information on the vendor website.

Kind regards,
Erwan.
