RK3568 开发板-安卓系统之mipi接口的摄像头驱动调试（十五）-rk3399 开发板

4.12 mipi摄像头驱动调试

4.12.1 查看原理图，获取需要配置的信息

4.12.2 需要配置的信息如下

1、两中mipi摄像头均挂在i2c4下

2、Camera0的复位GPIO是GPIO3_D4, 时钟信号是CLK_CIF_OUT

3、Camera1的复位GPIO是GPIO3_D2, 时钟信号是CIF_WIFI

4、通过查阅GC2053的规格书，及摄像头硬件，确认地址为0x3f和0x37

由于两个都是GC2053, 但配置的时候不能出现两个相同的节点，且由于是同一路I2C，所以也不能出现两个相同的地址。需要修改其中一个摄像头的地址

4.12.3 GC2053的最终配置如下

参考RKDocs/common/camera/HAL3/目录下的相关文档，最终确认配置如下

通过以上信息，可以看到成功注册了两个GC2053摄像头, 地址分别为0x37和0x3f

4.12.5 修改摄像头配置文件

修改摄像头配置文件hardware/rockchip/camera/etc/camera/camera3_profiles_rk356x.xml, 具体参考RKDocs/common/camera/HAL3/目录下的相关文档

4.12.6 测试摄像头

整体编译后生成update.img，烧写后就可以进行摄像头测试了

打开系统自带的相机，经过授权后，可以看到图像了

点击切换按钮，即可切换到另一个摄像头。
