器件型号：AM5728工具/软件：
您好、
我有基于 TI AM5728 EVM 的 (e2e.ti.com/.../am5728-unable-to-get-correct-capture-with-ov5640-green-pink-screen-issue 中提到的相同定制电路板。
我运行的是最新版本 Linux PSDK 9.03 写出来。 我做了与上述文章中描述的相同 DTS 更改。 （请参阅下面的 DTS 更改：-）
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>;
};
};
};
};
我在内核中启用了 ov5640 驱动程序、我也在处理它的所有依赖项。 我使用的驱动程序代码与中的驱动程序代码相同 Linux 9.03 PSDK 。 驱动程序的路径为：
/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
但摄像机设备未注册为/dev/video1（捕获设备）。 系统 /dev/video0 。
我已在每个函数中放入打印件 drivers/media/i2c/ov5640.c 和 /drivers/media/platform/ti/vpe/vip.c （请参阅下面的 dmesg 日志）
