IMX122

我在做DM368+IMX122的方案，通过DM368的I2C接口来控制IMX122的寄存器，IMX122工作在主模式，时钟是37.125MHz，复位是通过DM368的GPIO来实现的，且证实复位是有效的（先对IMX122的寄存器写，然后读回，再复位，在读回，最后读回的寄存器值为手册提供复位初始值，我是这样验证复位有效的），寄存器的初始化序列是在海思的方案上验证过

应该没有问题，只是在海思的方案上我们采用SPI方式来配置IMX122，现在是通过I2C来配置IMX122，现在的情况是，IMX122的HD,VD,PCLK均没有输出，想请教一下各位，是不是IMX122的I2C接口根本就不能用（我在122的手册上，没有看到I2C操作这部分，我是参考IMX138的接口来做的，寄存器的读写没有问题），有些头痛，先谢谢各位
