RK3588 点亮imx586摄像头

一.硬件原理图

mipi摄像头硬件确认点：

1.供电：5V，2.8V，1.2V，1.8V，reset脚（硬拉3.3，上电的时候从低到高），pwron脚外接

   3.3V。

2,时钟：MCLKOUT是24兆时钟。

3.4组差分mipi线。mipi的data线的波形为方波。

二.驱动移植

RK提供的默认sdk里面已经将支持的所有摄像头驱动都添加到了内核，所以不需要移植该驱动了。

需确认下移植驱动对应的一些信息

源程序
kernel/drivers/media/i2c/imx586.c

kernel/drivers/media/i2c/Makefile

kernel/drivers/media/i2c/Kconfig

kernel/arch/arm64/configs/rockchip_linxu_defconfig

Makefile脚本

• 驱动对应的宏开关

CONFIG_VIDEO_IMX586=y

添加设备树文件：

&i2c5 {status = "okay";pinctrl-names = "default";pinctrl-0 = <&i2c5m0_xfer>;imx586: imx586@1a {compatible = "sony,imx586";reg = <0x10>;  //插摄像头看iic5上出现的新设备后填入clocks = <&cru CLK_MIPI_CAMARAOUT_M1>;clock-names = "xvclk";pinctrl-names = "default";pinctrl-0 = <&mipim0_camera3_clk>;//需要和硬件确认是复用的哪个时钟，确认可以量到波形power-domains = <&power RK3588_PD_VI>;//reset-gpios = <&gpio3 RK_PC7 GPIO_ACTIVE_HIGH>;//现在硬件上是直接拉高，所以不用配//avdd-supply = <&vcc_mipidphy0>;//供电也是直接供电，所以不用配rockchip,camera-module-index = <0>;rockchip,camera-module-facing = "back";rockchip,camera-module-name = "default";rockchip,camera-module-lens-name = "default";port {imx586_out0: endpoint {remote-endpoint = <&mipidphy0_in_ucam0>;data-lanes = <1 2 3 4>;};};};

};

三.驱动调试

把驱动代码和设备树文件添加进去后就可以开始调试了。

使用i2ctool工具查看i2c5，发现有2个新的设别：0x10,0x50，猜测其中一个是senser，另一个可能是sensor的马达地址，尝试修改sensor的地址为0x10或者0x50看imx586能不能进probe函数。

当修改imx586的地址为ox10的时候，看imx586已经进了probe函数了。

从log可以看出imx586已经进了probe函数，但是并没有识别到sensor。

这时候，需要确认mipi摄像头上的供电是否正常，时钟是否正常。

经确认是sensor的一路供电没有，供电正常后可以设别到sensor。

到了这一步，可以确认，iic设备已经可以设别到sensor了，并挂载在iic5上面。
