Hi,
I have multiple custom cameras with the same components (sensor ar0820 and max9295 Serialiser), with some of these we can run nvgstcapture without problems and get the image but with others nothing happens, I managed to get these logs :

My guess is that the reset pin of the serializer is different for some cameras, is there a way to controle GPIO connections of the serializer inside the drivers kernel ?

Thank you

hello Vabre,

according to those logs I’ve only see your power sequences,
could you please share the failure messages, which camera you cannot enable the streaming.

BTW,
here’s developer guide for developing SerDes (Serializer-Deserializer) driver.
i.e. Jetson Virtual Channel with GMSL Camera Framework.
thanks
