Hi,

We experienced the following nvmedia camera related errors,
after the error happened the related cameras does not send new image frames.
This error happens after variable number of frames grabbed successfully (100 - 1600).
We saw this error on all of the three camera groups that has camera connected to it.

group A IMX490 on GMSL link: 3
group B IMX390 on GMSL link: 0
group B IMX390 on GMSL link: 1
group C IMX390 on GMSL link: 2

Can you help us to find the root cause of this problem?

Dear @laszlo.finta,
Is it using any NvMedia sample? If so, could you share the command?

We executed the following command and get the same result after some time:
./nvsipl_camera -c IMX490_RGGB_CPHY_x4 --link-enable-masks ‘0x0100 0x0000 0x0000 0x0000’ -d 0 -w 1

Dear @laszlo.finta,
I don’t see IMX490 camera module in supported sensor list given at DRIVE Ecosystem - Hardware and Software | NVIDIA Developer.

Dear Siva Rama Krishna,
As I mentioned in the ticket description we saw the same issue with all the cameras not just the IMX490.

We saw this error on all of the three camera groups that has camera connected to it.

group A IMX490 on GMSL link: 3
group B IMX390 on GMSL link: 0
group B IMX390 on GMSL link: 1
group C IMX390 on GMSL link: 2

The IMX390 cameras are listed in the supported sensor list, aren’t they?

8

Dear @laszlo.finta,
Could you just connect single IMX390 camera at A0 port and check running the corresponding command given at https://docs.nvidia.com/drive/drive-os-5.2.6.0L/drive-os/index.html#page/DRIVE_OS_Linux_SDK_NGC_Development_Guide/NvMedia/nvmedia_nvsipl_camera.html#wwpID0EPHA and confirm if it is working?

Dear @laszlo.finta,
Any update can be provided?
