Disclaimer: Do not unplug or disturb your Raspberry Pi or camera device while flashing new firmware. If you do, it will brick the camera and will be unusable. If you are uncomfortable doing this, please return your device to your distributor and get a replacement.
There have been some AI Camera production units that have been shipped with an older RP2040 firmware. The instructions in this post will allow you to update the RP2040 firmware to the latest version (v15 at the time of writing).
Preparation
Begin by using a fresh installation of Raspberry Pi OS and ensure your device eeprom/firmware and other software is up-to-date. This will allow the camera auto-detection on boot to work correctly.
To check if your firmware is out-of-date, boot your device with the AI Camera attached and run the following in a terminal window:
If you see the following output:
or
you will need to update to the latest version 15.
If the dmesg output shows a sensible firmware string like fw ver. 14, jump ahead to the Flashing section below. If your dmesg output shows fw ver. 4294967295, please update /boot/firmware/config.txt with the following:
1) Comment out camera_auto_detect=1 if present:2) Add the following to the bottom of the file:3) Reboot
After rebooting, the dmesg output should show a sensible firmware string like fw ver. 14.
Flashing
Once you see a sensible firmware string like fw ver. 14 in dmesg, download imx500_i2c_flash and main_v15.bin from this shared drive and save them onto your Raspberry Pi home directory.
Then, run the flash tool in a terminal window with:
and you should get the following output:
Testing
After completing the flashing, reboot the device and you should see the correct firmware version reported from dmesg:
The camera should now be detected by libcamera:
You can now revert the changes to /boot/firmware/config.txt to re-enable camera auto-detection. Note that you must be running the latest VC firmware/eeprom for auto-detection to work correctly with the AI camera.
