Hi Jacopo, Quoting Jacopo Mondi (2022-03-16 21:09:16) > The RDACM20 camera supports a single image format which is currently > listed as MEDIA_BUS_FMT_UYVY8_2X8. As the video stream is transmitted on > the GMSL serial bus, the 2X8 variant does not apply. > > Fix the format byusing MEDIA_BUS_FMT_UYVY8_1X16. > > This fixes a runtime error which is now triggered as the MAX9286 > deserializer implements .link_validate().
