OV10635 camera sensor with MAX9286-MAX96795 SerDes

Dear all,

We are setting up 5 OV10635 cameras that using SerDes on Xavier.
The first one is connected to MAX96705-MAX9288 SerDes and it could work as well.
The other four cameras are connected to MAX96705-MAX9286 and even one of them could not work.
I could verify that there was MIPI output from MAX9286 to Xavier but it was so difficult to confirm the correctness.
Then I tried to capture the image with simple v4l2 command and the result as below

v4l2-ctl -d /dev/video1 --stream-mmap --stream-count=1 --stream-to=test.raw

I’m wondering is there any way to check the correctness of MIPI data on Xavier side?

Any suggestion would be very appreciated.

Thanks and Best Regards,
Vu Nguyen

Hi Vu Nguyen,

In order to capture multiple cameras using the same deserializer you need to add support for virtual channel. For GMSL is also required to configure the OV10635 in FSIN mode.

You can find more info here: https://developer.ridgerun.com/wiki/index.php?title=GMSL_Virtual_Channel_ID

Regards,

Hi jchaves,

Thank for your reply. May I ask more question.
Do I have to enable virtual channel on Jetson Xavier and how can I do that?

Thanks and Best Regards,
Vu Nguyen

Hi Vu Nguyen,

From the Jetson Xavier side virtual channel is supported “out-of-the-box” in JetPack 4.2, that means you only need to make sure you assign the correct vc-id in the camera device tree, I advice to check the following file as reference:
hardware/nvidia/platform/t19x/common/kernel-dts/t19x-common-modules/tegra194-camera-imx390-a00.dtsi

Right now the sensor programming guide doesn’t explain much about this vc-id device tree property but you can also find more info about this here: https://devtalk.nvidia.com/default/topic/1057338/jetson-agx-xavier/gmsl-virtual-channel-id-support/post/5361427/#5361427

Regards,

-Jafet

Hi jchaves,

Thank for your useful info. First step, I just wanna make only one camera work well with MAX9286 and Xavier’s virtual channel in order to verify our hardware. So this is my device tree for 2 cameras, first camera is connected to MAX9288 and it worked well, the second one is connected to MAX9286.

I was wondering that if I have to modify the driver source code to enable XAvier’s virtual channel or just setting correct “vc-id” in device tree as above. And is there any way to check if virtual channel is enabled in linux user space.

Thanks and Best Regards,
Vu Nguyen

Hi Vu Nguyen,

I checked your device tree, you are using vc-id and vc_id properties correctly. Concerning your last question, I’m not familiar with the patches you’re using but you should check the virtual channel configuration in the deserializer (MAX9286), being set by the driver, that is, checking the register writes the driver is doing.

Hi jchaves,

Now I could capture one camera as well with MAX9286. But if I tried to enable two cameras, there was no data output from MAX9286 to Xavier.
Do you have any recommendation to check MAX9286 configuration to enable for multiple camera sensors?

Thanks and Best Regards,
Vu Nguyen

Hi Vu Nguyen,

Please refer to the quoted answer above. Basically after applying the changes in the device tree you’ll need to check the following in your patches:

  1. Check that the camera driver is configuring the OV10635 in FSIN mode.
  2. Check that the deserializer driver is configuring the chip to generate a frame sync pulse to the cameras.
  3. Check the deserializer driver is setting correctly the virtual channel for each input link.

Regards,

Hi jchaves,

Really thank for your help. I could capture 2 cameras of 4 channels as well.
Now I’m facing problem with I2C, if I tried to enable 3 or 4 cameras, I could not communicate with camera 3 or 4 by I2C. I’m digging into this I2C issue.

Thanks and Best Regards,
Vu Nguyen

Hello Vu and Jafet,

I have a similar system as you have described, and I can not get my MAX9286 to achieve frame sync lock when I have two cameras linked to the deserializer. I have my OV10635 configured to use FSIN, my MAX9286 is configured to use manual frame sync with appropriate frame period (confirmed with oscilloscope and it works with one camera), and the MAX9286 is set to use vertical frame combining and VC-ID to be set by link number. When I mask off one active link I can get a lock and the Jetson can stream both virtual channels, but of course the masked camera is all green.

Details of my debugging are here: https://devtalk.nvidia.com/default/topic/1072935/jetson-tx2/max9286-frame-sync-works-with-1-camera-but-fails-with-2-cameras/

Thank you for any help you can provide,
Andy
