IMX462 Camera on Waveshare CM4 IO POE

Raspberry Pi Cameras

Hello.

Today I got ArduCam IMX462 module from Amazon ( Amazon.com: Arducam for Raspberry Pi 5 Camera Module, IMX462 Color Ultra Low Light Camera, CMOS Camera with 141°(H) Wide-Angle M12 Lens, High NIR Sensitivity Camera for Raspberry Pi : Electronics ). CM4 module with 4GB memory and 32GB EMMC, latest Bookworm official image that works good with official IMX500. But I can’t get ArduCam IMX462. I found firmware update for B0444 but it is failed:
[INFO] Firmware Version: 0x10003

My config.txt:
#dtparam=i2c_arm=on

Enable audio (loads snd_bcm2835)

#dtparam=audio=on

Don’t have the firmware create an initial video= setting in cmdline.txt.

Use the kernel’s default instead.

What I have to do to fix it? Thanks

I found that problem is in tuning data that stored in camera. Tuning data is stage 2 in firmware update. Libcamera trying to read tuning data via i2c but got garbage and can’t decompress it and then crash. I made simple app to write tuning data via arducam-pivariety-sdk-dev but it is very unstable. It can write tuning data once but second call failed with the same error 2 as firmware update. After reboot I can write tuning data again but just once. Something wrong with current sensor firmware and have to be fixed by ArduCam. Also ArduCam have to change libcamera arducam helper to support ignoring tuning data in camera and load it from file.

I found the problem - low cpu speed on fimware upgrade. For some reason firmware upgrade unstable on low cpu speed. Once I turn performance scaling governor “echo performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor” I was able to finish firmware upgrade without errors and now camera works fine.
