STM32MP135F-DK raspberry pi camera module v2.1

[kagan_senkeser]

Hello,

I have STM32MP135F-DK board and raspberry pi camera module v2.1 but board does not see camera
I guess I have to modify stm32mp135f-dk.dtb file. 

But how should I write settings like OV5640 or GC2145 in dtb file
like that

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 = "okay";

port {

gc2145_ep: endpoint {

remote-endpoint = <&mipid02_0>;

clock-lanes = <0>;

data-lanes = <1 2>;

};



And after chaning that file should I do anything to take photo with raspberry pi camera module v2.1

Hi @kagan_senkeser 

It may be worth considering the STM32MP257F-EV1 or STM32MP257F-DK (due to be available in January 2025) development boards for the STM32MP257 microprocessor - the STM32MP257 has a built-in MIPI CSI-2 interface whereas connection to a MIPI CSI-2 camera from the STM32MP135 was via an external chip.

The Raspberry Pi Camera Module v3 has a significantly newer senor than v2.1 and may also be well worth trying.
