But this CVS device still works in non-binned mode. Are the exact limitations known? Is this CVS device used in other systems? Staggered HDR isn't supported in upstream in any case. > But our sensor driver only supports 1928x1088@linear mode. > It could have unexpected issue while this device has CVS board. One way to address this would be to set the minimum image size to some larger, known to work size, for that CVS device in the CVS driver. This may require changes on libcamera side, too, but that's a separate issue. -- Kind regards, Sakari Ailus
