I am experiencing troubles in make it work imx477 with OAK-4P-POE.

The problem happens within the Arducam ircut (https://www.uctronics.com/camera-modules/camera-for-raspberry-pi/high-quality-camera-raspberry-pi-12mp-imx477/arducam-12mp-imx477-ir-cut-filter-auto-switch-camera-for-jetson-nano-xaviernx-b0274.html ), used in this blog article ( https://discuss.luxonis.com/blog/4922-oak-cameras-for-ndvi-perception ).

Result of our tests:

OAK - Using two camera, test without additional rpi-adapter:
No-camera detect
OAK- Test within a single camera:

OAK -Test with a official RPI HQ IMX477 camera:

CM4 board : Test of of 477p arducam ir-cut:
They work good as expected

Then we performed tests within the official RPI-Adapter that is declared working for both OAK-4P-POE and imx477.
We see that the chain of FFC and adapter limit the number of connected lanes to 2.

The variant we have in the office is a little bit different (w/o CS mount,..) but the underlying sensor and CBA board are the same.
I tested with 4P (r5m1e5) --UC 796 cable -- UC517 (imx 477 - though detected as 577.)
I have no issues with streaming.

You shouldn't need a RPI adapter since the cable is 22pin to 26pin which should work out of the box. Can you test that?

EDIT: from tests on 4P-POE, it only works on 4L sockets. I get the same error as you on CAMB and C.

Thanks,
Jaka

Ok, found right cable.
We already did it and no detection.

I retest it now with 1 Ircut on CAMD:

CAM is power and i can listen clearly the ir-cut filter switch if i cover fotoresistor.
But it does not detect any cam

Do I have to delete calibration?

Official RPI camera via uc-796 +rpi-cam-adapter on camD

Lets do a mixed test:

Then on CamD the official HQcam via adapter and on CamA the ir-cut.

I'm slightly confused now. You want to make IR-CUT work but is not detected in any case? (talking about the small camera, that is connected to the CAM_A socket). The HQ RPI camera is the one with a CS lens, on CAM_D. This one works with the RPI adapter, as expected. Please correct me if I'm wrong. The link you sent is for the CS mount camera which is the one on the CAM_D. Or were lenses swapped?

If that is the case, can you check if cable is correctly connected on the IRCUT. In some variants the connectors are top down, which is often a source of confusion.

Thanks,
Jaka

oaz

jakaskerl I just swapped m12-to-cs with a pure m12 with ir-cut but it is the same camera as in CamD.
All the cams have been sucessfully tested with raspberry, but no any success test on oak-4p-poe.
We did double check to cables.
The only way we can see camera are detected (but not working, just cam detect) is by using rpi-adapter like u can see with the CAMA in this photo.

jakaskerl

oaz
Ok, I'll sync with the team on the best course of action.

Thanks,
Jaka

oaz

jakaskerl Let me be more precise. The cam with m12 (CAMA) is ir-cut camera ardulink, it is not exact the same we see on CAMA (the official RPI), but it is the correct arducam that they sell with cs mount .
thank you Jak

Hi @oaz , sorry for the late reply here...
I checked the camera module PCB from our blog post (https://discuss.luxonis.com/blog/4922-oak-cameras-for-ndvi-perception), and it looks a bit different, as in this picture:

See the unpopulated IC in the bottom-right corner of the image above.
On your module that chip is present, and I'm afraid it's an MCU interposed between the I2C bus on the 22-pin connector and the I2C of the sensor, implementing the PiVariety protocol (not sure if 477P stands for this), that unfortunately we don't support at this time with depthai:

Would it be possible to post a close-up photo?
