  • Pre-configured RPi image not working on RPi 4

Hi Support,

I try to get the OAK-D Lite to work on a Raspberry Pi 4. I flashed OAK_CM4_POE_V10_64bit and tried using SSH with -X. When I run the command "python depthai-python/examples/MobileNet/rgb_mobilenet.py" I receive a error message: "[1844301061F5620E00] [1.1.2] [1.103] [system] [warning] ColorCamera IMX214: capping FPS for selected resolution to 35

qt.qpa.xcb: could not connect to display

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/home/pi/.local/lib/python3.11/site-packages/cv2/qt/plugins" even though it was found.

This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem."

I wonder if you have any advice?

Hi Jaka,

 

Thank you for helping!

 

I tried with adding the `export DISPLAY=:0` in the command line after logging in, but I received the same error message, please see below.

I am not sure if I just write this command straight in the command line.

Hi @tboive
Ah, you are running from windows. I don't think X11 server is enabled on regular CMD. You need to use putty and explicitly enable the X11 forwarding.

Hi, Team!

I have same initial soft and hard parts: OAK-D lite and flashed OAK_CM4_POE_V10_64bit image on uSD. I connect RPi 5 8Gb to monitor with HDMI and see just black screen i.e. no signal. While RPi without uSD booted as expected. I suspect that I should correct something in config…

Is anyone faced with such issue?

    @jakaskerl , thanks! I will try given steps.

    Yes, without uSD it booted in BIOS (here uSD was inserted later):
