LI-OV10635-GMSL Camera On Xavier through CSI interface

Hi,

I am planning to use LI-OV10635-GMSL camera on Xavier through CSI interface. We are connecting the camera using Connect Tech’s GMSL camera expansion board which has 4 MAX9296 deserializer.



The LI-OV10635-GMSL camera has an OV10635 censor + MAX96705 Serializer. Also, I am pretty sure that MAX96705 == MAX9271 from the software point of view because they have the same registers and same pins.

So, the overall system is like this:
OV10635 <—> MAX9271(serializer) <—> MAX9296(deserializer)

I can find MAX9296 linux driver from Jetpack4.3, but I couldn’t find the OV10635 driver nor MAX9271/MAX96705 driver.

Is Nvidia Jetpack currently support LI-OV10635-GMSLcamera?
Where can I get/find the driver for OV10635 and MAX9271 serialier?
I couldn’t find any information for MAX9296 deserialier, is it same as MAX9286 deserializer? same pins and regs?

Shuo

Need to get the driver and dtb from Leopard for this module.
Please contact with Leopard to get the support.

Hi,

I contacted Leopard. But they don’t have driver for it yet through CSI interface.
They only support accessing it through USB3 interface.

Thanks,

Hi,

I forgot to mention that from here, it seems this guy found a OV10635 driver.

And its heading is:

/* ov10635.c - ov10635 sensor driver
 *
 * Copyright (c) 2016, NVIDIA CORPORATION.  All rights reserved.

Why I don’t see it in Jetpack driver source. I checked 4.3, 4.2.2. None of them has it.

Thanks,

Sorry, I have one more question:

If we are accessing camera through CSI + GMSL (serialier + deserializer), in side camera driver code, does it need to call serializer and deserializer functions to setup control, streaming, and so on?

I saw inside imx390 driver, it calls max9296 and max9295 functions to do that. But for other driver, e.g. AR0330 driver, it doesn’t do that.

Hi @lunarking1028,

RidgeRun has drivers available for SER/DES as well for OV10635 cameras. You can get more information here:

It looks like your drivers works with MAX9286 deserializer.
However, the deserializer board I have is using MAX9296 deserializer.
Will your MAX9286 driver work with MAX9296?

Thanks,
Shuo

We have had worked with MAX9296 in the past for other cameras, you can get further information if you request a full estimate. You can write to support@ridgerun.com

Jetpack only include the reference driver. The ov10635 isn’t in the reference list.
