20240907在友善之臂的NanoPC-T6开发板使用Rockchip原厂的Buildroot点亮imx415

2024/9/7 18:21

缘起，最新需要调试MIPI YUV摄像头，先拿Rockchip原厂的Buildroot自带的IMX415来练手了！

貌似地球上没有MIPI接口4LANE的YUV的摄像头。

飞凌OK3588-C适配了OV5645（MIPI接口，YUV格式，2LANE）

由于买的IMX415摄像头的从机地址是0x37【2条地址选择脚全部拉高】

默认是0x1A【2条地址选择脚全部拉低】

在这里浪费了几天时间/折腾了好几天！

IMX415的驱动咋也挂载不了！^_也不知道原因！

port {

③出现MIPI 相关报错

出现MIPI相关的报错，比较常见的是出现crc的报错刷屏：

[ 2266.859853][ C0] mipi2-csi2 ERR1:0x1000000 (crc,vc: 0)

[ 2266.859862][ C0] mipi2-csi2 ERR1:0x1000000 (crc,vc: 0)

[ 2266.860160][ C0] mipi2-csi2 ERR1:0x1000000 (crc,vc: 0)

[ 2266.860167][ C0] mipi2-csi2 ERR1:0x1000000 (crc,vc: 0)

出现上述mipi相关的报错，crc/ecc等报错，本质上都是与phy层的mipi信号相关，可能原因如下：

驱动配置的MIPI时钟与sensor输出的MIPI时钟对应不上

MIPI时序错误，例如SOT的时序不符合MIPI的SPEC

MIPI信号质量不佳导致的报错

示波器测量可以确认sensor输出的MIPI时钟大小，驱动需要与其对应，MIPI信号质量的问题，可以通过将驱动的xvclk降低到12M/6M，如果降低后没出现MIPI的报错，那么需要排查硬件的走线等等。MIPI时序的问题，建议测量MIPI信号，看是否符合spec，后面再写文章来介绍这部分。
