Tool/software:
Hi,
I have the same custom board as mentioned in (https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1008216/am5728-unable-to-get-correct-capture-with-ov5640-green-pink-screen-issue?tisearch=e2e-sitesearch&keymatch=am5728%252520ov5640#) based on TI's AM5728 EVM.
I am running the latest Linux PSDK 9.03 on it. I have done the same dts changes similar to what is described in the post above. (See dts changes below:-)
clk_ov5640_fixed: clk_ov5640_fixed {
compatible = "fixed-clock";
#clock-cells = <0>;
clock-frequency = <24000000>;
};
clk_ov5640: clk_ov5640 {
compatible = "gpio-gate-clock";
#clock-cells = <0>;
clocks = <&clk_ov5640_fixed>;
enable-gpios = <&gpio5 18 GPIO_ACTIVE_HIGH>; //[04] changed in VIC2 from ACTIVE_LOW
};
&vip2 {
status = "okay";
};
&vin3a {
status = "okay";
port {
vin3a_ep: endpoint {
remote-endpoint = <&cam>;
slave-mode;
bus-width = <8>;
data-shift = <0>;
hsync-active = <1>;
vsync-active = <0>;
pclk-sample = <0>;
};
};
};
&i2c3 {
status = "okay";
clock-frequency = <400000>;
ov5640@3c {
compatible = "ovti,ov5640";
reg = <0x3c>;
status="okay";
clocks = <&clk_ov5640>;
clock-names = "xclk";
powerdown-gpios = <&gpio5 17 GPIO_ACTIVE_HIGH>;
port {
cam: endpoint {
bus-width = <8>;
data-shift = <0>;
hsync-active = <1>;
vsync-active = <0>;
pclk-sample = <0>;
remote-endpoint = <&vin3a_ep>;
};
};
};
};
I have enabled ov5640 driver in the kernel and I too am taking care of all its dependencies as well. I am using the same driver code which is present in Linux 9.03 PSDK. Path for the driver is -
/opt/ti-processor-sdk-linux-am57xx-evm-09_03_06_05/board-support/ti-linux-kernel-6.1.119+gitAUTOINC+e4e8b16e66-ti/drivers/media/i2c/ov5640.c
But the camera device is not getting registered as /dev/video1 (capture device). Only /dev/video0 is showing.
I have put prints in each function in drivers/media/i2c/ov5640.c and ./drivers/media/platform/ti/vpe/vip.c (See dmesg logs below)

What am I missing?
Please help resolve this !
