我直接编译的整个osrv，需不需要重新配置一内核呢，勾选一些i2c的选项

很明显，I2C不通。
1、检查硬件；
2、查看ls /dev下边有好几个i2c，实际用的是哪一个？修改nvp6124驱动下边的 i2c_adap = i2c_get_adapter(0);
i2c-0,i2c-1,i2c-2???具体是哪一个
static int i2c_client_init(void)
{
struct i2c_adapter* i2c_adap;

#ifdef HI_CHIP_HI3521A
printk("HI_CHIP_HI3521A\n");
i2c_adap = i2c_get_adapter(0);
#else
printk("HI_CHIP_HI3516A\n"); //printk("HI_CHIP_HI3531A\n"); //
i2c_adap = i2c_get_adapter(2); //i2c_adap = i2c_get_adapter(1);
#endif
nvp6124_client = i2c_new_device(i2c_adap, &hi_info);
i2c_put_adapter(i2c_adap);

return 0;
}
