关于VIN中media bus fmt和pixel code得问题

[inomec]

平台：V536H，系统版本：Tinalinux 4.9，CMOS:MT9J003

我在驱动中把mbus_code 设置为MEDIA_BUS_FMT_Y8_1X8，应用中读取得时候设置pixelformat =为V4L2_PIX_FMT_GREY

static struct sensor_format_struct sensor_formats[] = {
    {.desc = "RAW Bayer Y 8bit",
     .mbus_code = MEDIA_BUS_FMT_Y8_1X8, 
     .regs = sensor_fmt_raw,
     .regs_size = ARRAY_SIZE(sensor_fmt_raw),
     .bpp = 1},
};

报下面这个错误，请问VIN是不支持这个格式吗？
95.682933] [VIN_ERR]vin is not support this pixelformat:12289
[ 95.689513] [VIN_ERR]vin_pipeline_try_format failed
