海思3403接入索尼sensor，报mipi错误，detect data info分辨率为0

SS928
 
SD3403
 

此时寄存器读写是正常的，mipidata会有固定的几个数值来回跳变。

  1. mipi 线序检查一下 是不是0 1 2 3；
  2. sensor clk 时钟给的对吗？
  3. mipi_data 有1 lane 没有数据；
  4. 可能寄存器配置有问题；

1、确认过是0123
2、这个值得是soc给sensor的参考始终吗？我分别尝试了修改soc的参考时钟，对应修改sensor输入时钟寄存器，74.25和24均没有效果
3、mipidata的最后一栏一直为0所以没有数据，这个是不是应该排查下硬件
4、寄存器序列是供应商提供的表格，按照对应lane和帧率进行配置的。

mipi数据一直在这两组数值之间跳动

  1. 时钟是soc给sensor的时钟，sensor0 clk地址是0x11018440, 具体数值跟寄存器初始化序列有关；
  2. 关注一下coms.c文件中宏定义， Vmax Hmax 等寄存器；
  3. 如果一直没数据排查一下lane3

mipi error 一直有报错，说明sensor 已经有数据了，只是解析不出来；很大概率是驱动有问题

1、用海思自带的工具读取11018440寄存器的地址能获得soc给sensor的时钟是74.25Mhz，对应的sensor输入时钟寄存器是3014，复制为0，这样应该可以保证时钟是正确的。
2、检查过Vmax寄存器数值是对的，但是寄存器个数太多，很多寄存器没有标明实际作用，这个有没有排查方向，
3、为什么要排查lane3，是因为其他几lane有数据的时候他数值一直是0，所以怀疑这一lane硬件有问题吗

另外，我们sensor模式使用的master模式，不知道这个会不会有影响

  1. sony 时钟设置还有一堆寄存器也要改
  2. 寄存器得自己看了
  3. 是的，不过应该不是硬件问题

我把寄存器序列贴出来了，没有看到其他关于sensor时钟配置的寄存器，能帮我看一下吗

xlsx表格中的初始化序列 那时钟没问题，芯片手册里改时钟有很多相关寄存器

我用自带的寄存器读写工具读到了0x11018440寄存器的地址，获得的数值是74.25Mhz，我上上条的回答截图里有贴出来

挨個排查寄存器序列，最終發現是寄存器序列問題

看起来是lane id配置错误，你截图的2c就是raw12，01就是frame end。但是却对应的是lane1，datatype应该对应lane0
