Hi! I am working with the Jetson Nano Board and the Sony IMX290 (MIPI-CSI2) 2-lane camera and I have modified the device driver according to the “Driver Programming Guide”, the file is attached bellow. The camera is connected to CSI_C and I can detect /dev/video0 entry, also when I run:
$ v4l2-ctl –list-devices
I can see that the port bindings are correct. But, when I try to test the camera and take an image with the command:
$ v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat='Y10 ' --set-ctrl bypass_mode=0 --stream-mmap --stream-count=1 --stream-to=-test.raw
The camera is stuck in a loop and the .raw file is empty. In the dmesg log I get this output:
[ 247.045714] vi 54080000.vi: TEGRA_CSI_PIXEL_PARSER_STATUS 0x00004000
[ 247.052931] vi 54080000.vi: TEGRA_CSI_CIL_STATUS 0x00000012
[ 247.058639] vi 54080000.vi: TEGRA_CSI_CILX_STATUS 0x00060060
[ 247.064733] video4linux video0: tegra_channel_capture_setup(): valid_ports=1: width,height=1920,1080 word_count=2400
What I got from reading the CSI registers in the TRM manual it seems that the start sequence is not correct, but when I look at the start sequence on an oscilloscope it looks like the sequence stated in the camera manual.
Also, when I run the v42l-compliance test I get some errors, but I am not sure what they mean.

Any ideas what could be wrong?
Thank you in advance!
