Preferred Debian Version as of May-2023, Picar-X

I’m running into problems with the module installation scripts. I have tried Buster, Bullseye32, and Bullseye64. Bullseye32 is the best of them so far, it only fails with the script, hardware not supported. So, I just want to back up now and ask, of someone at SunFounder, or someone who has very recently done a full install, which is the preferred version?

Once I have that sorted out, I will start talking about the errors I am encountering in that version.

Thank you,

Phil Avery

Yes, for now you start with Bullseye32 and if you encounter a failure in the script, the hardware is not supported.
You then run curl -sS | bash
instead of sudo bash and reboot the Raspberry Pi system.
After that go and execute
cd /home/pi/picar-x/example
sudo python3
See if you can make a sound.

Thank you. I have made great progress thanks to your assistance so far.

During the vilib installation, I am encountering this error:

I do not know what this means, but I continued on. This does not seem important for now.

I did find a more important problem. When I enable the camera in raspi-config, it causes VNC to fail. My version of raspi-config is slightly different, it refers to Legacy Camera.

After enabling this and rebooting, VNC shows this screen:


I have found a work-around, if a monitor is connected directly to the Raspberry Pi during boot, VNC will connect, and the camera works, at least to the degree that the Computer Vision example works.

This is obviously not ideal, it would be better if the Picar-X could be fully functional without having a monitor connected while booting. I can move ahead, but any suggestions to be able to boot the car without a monitor, and have it completely working would be greatly appreciated.

Again, thank you for your help so far.

You should use ssh to connect to the ip remotely if you encounter this situation, or use the putty tool to connect to the IP.
Let’s use the putty tool to connect to the ip and execute sudo raspi-config to enter the setup page.
For the operation, please see our image at

After restarting the Raspberry Pi system, go to vnc and open the remote connection to see.

Thank you once again. Unfortunately, setting vnc resolution to 1024x768 did not solve the problem. If the camera is enabled via raspi-config, VNC shows the black screen with ‘Cannot currently show the desktop’. If I disable the camera in raspi-config, VNC works properly.

However, I did get it working properly with another method, so this is no longer a problem. Here is what I did:

Edit config.txt with sudo nano /boot/config.txt

Uncomment this: hdmi_force_ hotplug=1
Uncomment this: hdmi_group= 1
Uncomment and set this: hdmi_mode= 16
save and reboot

This problem and this solution can be found at:

I do, once again, thank you for your prompt replies and suggestions. I believe my Picar-X is now fully functional. If I have further issues, I will start a new thread. But I think this is enough to keep me working for quite some time.

Best Regards,

Phil Avery
