ISP bridge and YUV modes support are not implemented in the driver, but you're probably already aware of that. I unfortunately have no straightforward answer. Try tracing the ISP interrupts and monitoring the CCDC SBL busy bits to see if the CCDC writes images to memory correctly. -- Regards, Laurent Pinchart -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
