Dear all：
本人在米尔的i.MX8M Plus开发板上适配OV4689，内核版本为5.10.9，sensor配置为8bit raw，4 lanes，1280x720，60fps

重新抓raw，输出格式变为AR24

最后是获取到图片都是异常，请大伙帮忙看下是哪里的问题。
另外这里还有个问题，imx8mp平台默认不支持10bit raw，所以我把sensor配置成8bit raw，但如果要支持10bit raw，在上面的mxc_isi_out_formats结构体中添加10bit raw相关数据也不能正常获取raw数据，网上搜到都是在4.几的内核上修改的，不知道还修改哪里的驱动文件，望告知，谢谢！
我查看了 i.MX 8M Plus Camera Sensor Porting User Guide.pdf 中的 Chapter 6 Camera Sensor Driver in V4L2 Mode，这一章中提到的sensor驱动文件，我这边内核目录没有找到该路径，甚至连vvcam文件夹都没有，好像这文档没有太大的参考作用。
我这边适配OV4689是在 drivers/media/i2c/ov5640.c 上修改过来的，目前sensor是有数据，但最终出图有异常。
你好！
我在运行isp_media_server的时候出现如下错误
第一个终端
第二个终端
我在这里[IMX8MP][ISP] isp_media_server crashes at camdev::SensorOps::queryCaps() 看到一样的问题，但没看懂是怎么解决的，请问这个问题是要怎么解决的？
