Raspberry pi Camera overlay on ubuntu

[Fai_S]

Issue: Unable to detect Raspberry Pi Camera v1.3 on Radxa Zero 3 running Ubuntu 22.04 LTS. (Joshua-Riek image)

Steps followed:

1. Downloaded and Installed Required Packages:

   • I installed rsetup from https://github.com/radxa-pkg/rsetup using sudo apt-get install ./rsetup_0.4.11_all.deb.
   • I also installed librtui from https://github.com/radxa-pkg/librtui using sudo apt-get install ./librtui_0.1.6_all.deb.
   • After installing rsetup, I gained access to the u-boot-update command, though rsetup itself didn’t list any overlays as it typically does in Radxa OS.

2. Followed Camera Overlay Instructions:

   • I referred to https://github.com/Joshua-Riek/ubuntu-rockchip/wiki/Ubuntu-22.04-LTS for guidance.
   • Created a directory for device-tree overlays: /lib/firmware/device-tree/rockchip/overlay/.
   • Copied the camera overlay file radxa-zero3-rpi-camera-v1.3.dtbo into this new folder.

3. Modified U-Boot and Updated Configuration:

   • Edited the U-Boot configuration file as per the instructions.
   • Ran sudo u-boot-update, which resulted in the message “updating /boot/extlinux/extlinux.conf…”.
     
     
     
     
     
     
     
     

4. Current Issue:

   • Despite these steps, the camera is still not detected when I check with ls /dev/video.

Request for Assistance:
I would appreciate any guidance on additional steps I might need to enable the camera on this setup or troubleshoot the overlay configuration. Thank you!
