Picar X v1, vilib install fail with raspios Legacy (bullseye)

Robotic kit for Raspberry Pi
1

I ordered my PiCar-X several monthes ago and received V1.
Assembly is done and was a great experience with my son but following the " Install All the Modules" part of the documentation lead to an error installing vilib
Installed OS: raspiOS legacy with rpi-imager
SSH access is OK, camera is functionnal with another SD-card installed with EZblock

rpicam-apps seams to not be available to install, libcamera-hello is present and functionnal.
Can you help us ?

Do you mean installing all the library codes on the EzBlock OS image system?

EzBlock OS is not compatible with installing all those library codes. You need to prepare two SD cards: one for controlling with the EzBlock app and another for controlling with Python. They cannot be used on the same SD card.

There are two ways to operate:

  1. Python Control: This involves downloading and installing all the codes on the Raspberry Pi OS and using Python commands to control the PiCar-X product. You can find more information here: Play with Python.
  2. EzBlock APP Control: This requires installing the specific EzBlock OS image to connect and work properly with the app. More details can be found here: Play with EzBlock.

Thanks for your reply but no, its not what i mean.
I installed RaspiOS Legacy and followed “Play with python” documentation, then i encoutered a prolem with the installation of vilib.
I did a test with another SD-card on wich i installed EZ-block, only to validate that the camera was functional.
I think there may be a problem with the rpicam-apps dependency

If I’ve correctly understand your question, then, it was only since Raspberry Pi OS Bookworm that the camera capture applications were renamed from libcamera-* to rpicam-*

So if you’re using a legacy OS, it won’t be available. So I think you either need to upgrade OS to bookworm, or downgrade picarx SW to legacy.

If I’ve misunderstood the query, then check here for more information

Yes. SPF650 is correct.
We recommend installing all library codes using the new Bookworm system.
