Hi,

Having flashed the 8.0 Software release, next I tried to test the camera (SF3325) supplied with the development kit.

I ran the ipp_raw sample. The camera seems to be correctly detected but there’s an error further down.

nvidia@tegra-ubuntu:~/drive-t186ref-linux/samples/nvmedia/ipp_raw/egldevice$ sudo ./nvmipp_raw -cf ../ddpx-a.conf -c SF3325-CSI-A -d 0
Max96712 Rev 2 detected!
Sensor AR0231 RCCB Rev7 detected!
nvmedia: ERROR: Couldn't open device file 'drm-nvdc'
nvmedia: ERROR: InteropInit: failed to initialize egl 
nvmedia: ERROR: main: Error in InteropInit

What am I doing wrong?

Thanks,
Punit

I’ve found what I was doing wrong.

Alongside the egldevice/wayland directory there is also the ‘x11’ folder. Running the binary from there shows the output from the camera.

Hi Punit,

I was wondering if you have an idea how to view an SVC210 GMSL camera on the AGX?

Thanks.

Sorry, don’t have any experience with SVC210.
