Hello,
We have The DRIVE AGX Pegasus DevKit running Software 10 and OS 5.1.6.1. We are using MATLAB GPU coder to implement an object detection algorithm we wrote. We got our model to work using a USB camera but we are having some issues when we attempted to use the Sekonix SF3325 camera connected to Port A0.

The GPU Coder uses the v4l2 api to gain access to the camera attributes.

  1. Is there a way to get the v4l2 api to access our camera connected to Port A0?
  2. What do we need to do OR add to make our Sekonix SF3325 visible to v412.

Thanks for your help as always

Best Regards
b.baykeda

Dear @d.baykeda,
We have not tested v4l2 APIs to access GMSL cameras. We recommend to use NvMedia/DW APIs to access GMSL cameras.

Dear @SivaRamaKrishnaNV ,
Thanks for your reply.
Does this mean you don’t have access to any drivers or way to use the v4l2 API? Any pointers to make this work would be appreciated as this is a road block for us.
If you also know of ways to use NvMedia/DW APIs from MATLAB GPU coder to access GMSL cameras, that would be helping us out a great deal.

Hi @d.baykeda
No, we don’t work on the integration of V4L2 API or MATLAB GPU coder on DRIVE.
Maybe you can contact MathWorks and see if they can help. I found there are some posts and GTC sessions provided by them, not for DRIVE though, e.g. https://developer.nvidia.com/blog/using-matlab-and-tensorrt-on-nvidia-gpus/.

Dear @VickNV ,
Alright, Thank you.
