hi3516+AR0134 Sensor 寄存器写失败

     Sensor 驱动中初始化Sensor, 寄存器写失败，但是用i2c_write 命令却能写入，这是什么原因呢？

如下
代码中写入：
sensor_write_register(0x30D4, 0x6007);                  // COLUMN_CORRECTION     

        错误：
        hi_i2c_wait_txfifo_notfull->241:
       wait timeout, auto_satatus: 0xb0010000!

        I2C_WRITE error!


命令写入：
~ # i2c_read 0x0 0x31 0x30D4 0x30D4 2 2 2
