In version R35.4.1, using jetson orin nano adapted to the RAW14 data format of the IMX294 camera, the image cannot be previewed

The driver of IMX294 has been developed, and the frame rate can be printed using the v4l2-ctl command normally.

nvidia@tegra-ubuntu:~$ v4l2-ctl -V -d /dev/video1 --stream-mmap

When I used the argus_camera and nvgstcapture-1.0 commands, I didn’t see a normal image. As follows:

As shown in the figure above, when using argus_camera and nvgstcapture-1.0 commands, dmesg appears as follows:

What do I need to do to preview the sensor’s image properly? Hope to get your help very much!!!

Please update to J5.1.3(r35.5.1) for RAW14.


Previously, in R35.3.1, it was possible to light up by replacing the and files. Could you please provide the replacement file required by R35.4.1? Let me have a try.

I would suggest to migrate to r35.5 that make sure support RAW14 format.
