Hello,

First: I was able to use B0263 stereo module correctly connected to the “CAM0” port on Jetson Xavier NX kit.

Second: I connected B0223 camera to the “CAM1” port and I tried to used both camera at the same time. It worked during some time and after I restart my system.

After Restarting the system, the B0263 stereo module does not provide frames. I am able to get this output:

nx@nxkit:~$ v4l2-ctl --list-formats-ext
ioctl: VIDIOC_ENUM_FMT
Index : 0
Type : Video Capture
Pixel Format: ‘GREY’
Name : 8-bit Greyscale

Index       : 1
Type        : Video Capture

Type        : Video Capture
Pixel Format: 'Y16 '
Name        : 16-bit Greyscale
	Size: Discrete 2560x800

But when I use the demo script I get this:

MIPI_Camera/Jetson/Jetvariety/example$ python3 arducam_displayer.py
Firmware Version: 3
Sensor ID: 0x9281
Serial Number: 0xADA4B931
select timeout
VIDIOC_DQBUF: Resource temporarily unavailable
Traceback (most recent call last):

frame = frame.reshape(int(h), int(w))
AttributeError: ‘NoneType’ object has no attribute ‘reshape’

I have verified connections several times, change to other flat cable but the problem persist.

Please help me.

Hi @jeslava
Thank you for the information,
So it can work normally every time, until you restart the system?

I need to confirm some information:

  1. When it is not working, will the green LED on the back of the module flash a few times when running camera commands (only in the first few seconds of executing the command)
  2. Complete dmesg log when the camera is not working
