DM368的采集设备注册

Other Parts Discussed in Thread: TVP5150

请教一下

将 Board_dm365_evm.c  的 数组变量 vpfe_sub_devs[ ]  里的 .grp_id = VPFE_SUBDEV_TVP5150  改为  VPFE_SUBDEV_MT9P031 后,通过 ioctl ( ) 调用底层的函数指针时发现都为空。如通过 ioctl(VIDIOC_ENUMINPUT)-----> ops->vidioc_enum_input( ) 时发现 ops->vidioc_enum_input( ) 为 NULL 。

是否在vpfe_capture.c注册设备时没有与VPFE_SUBDEV_MT9P031生成的设备文件联系起来?
