Hires cam not working with voxl2

@Alex-Kushleyev Thank you for the advise , I have been using the kernal image which includes M0173 breakout board.

@voxl-phoenix please make sure the cameras are connected as shown in C26 configuration https://docs.modalai.com/voxl2-coax-camera-bundles/

@Alex-Kushleyev
Yeah I did follow the exact camera connections given on C26 configuration except that I don't have a down tracking camera. everything else is same. It's weird that it worked at start and than no response at all. -

@voxl-phoenix , can you please confirm something - did you mention that this exact hardware setup was previously working with 4 cameras and now two cameras are no longer detected?
Regarding camera calibration, it seems the issue is that the calibrator is attempting to calibrate extrinsics (which is only done for a stereo camera setup), but you are only calibrating one camera. Let me look into that.

@Alex-Kushleyev I have only three cameras one TOF, Tracking, Hires each. TOF and Tracking are working properly.
for calibration I',m just calibrating Tracking camera with fish eye
voxl-calibrate-cameras -f -s 8x5 -l 0.029it is trying to calibrate extrinsics automatically.

Ohh, sorry for the confusion. I misread your original post and thought that you have 4 cameras connected, like C26 configuration.
Can you please disconnect your M0173 from VOXL2 and take a picture showing the connectors on M0173 and where each camera is connected? just to double check.

@voxl-phoenix , the connections look correct. Can you please clarify whether this setup was working (hires camera was working) and then suddenly stopped working? Or what changed between the time when it was working and now.

@Alex-Kushleyev I have got this camera two days back and I have connected it and tested them both they, worked fine. I had to unbrick my board so I unbricked it and installed new SDK 1.4.1.
It was working fine before and after installation. I have just disconnected the camera and conected it again, because I was installing it in the holder that I 3D printed, just before installing I have tested it once, it is not working since than. only once I have disconnected the cable and connected it again, it stopped working. I have checked there is no damage to cables or board. I have handled them properly.

@voxl-phoenix , I think you also mentioned that you tried swapping the cables between tracking and imx412 camera, right? If so, it seems something got damaged in the IMX412 camera during connecting / disconnecting. For disconnecting the cables, we suggest using a special tool, please see https://docs.modalai.com/micro-coax-user-guide/#-proper-cable-and-adapter-handling- .
Also, it is hard to say for sure where exactly the issue is - M0173 board or IMX412 camera. the only good way find the cause is to replace components one at a time.
Just to elaborate on the symptoms that you are seeing :
voxl-camera-server -lcommand essentially probes all the cameras (based on the sensormodule files located in /usr/lib/camera). Probing involves turning the camera on via the reset GPIO and attempting to talk to the camera via I2c interface. If the camera responds, the probe is successful, otherwise failed. In your case, the probe of IMX412 failed, which means either the camera could not be turned on for various reasons or the i2c communication was not working.If you have another tracking camera AR0144, you could connect it instead of the IMX412 and see if the probe succeeds. You would need to add
/usr/share/modalai/chi-cdk/ar0144/com.qti.sensormodule.ar0144_1.binfile to/usr/lib/camera(which is the AR0144 sensormodule for the camera slot 1, where the IMX412 is currently connected). Then if you runvoxl-camera-server -land detect two AR0144 cameras (3 cameras total) then i2c communication and power should be working).Alex
