@Morten-Nissov ,

Is it just the specific camera (tracking) not working in a specific port? what if you connect TOF or IMX214 camera there?

For your configuration using the M0135 interposer, kernel variant 2.0.0 is the correct one to use. Using kernel 2.0.2 will result in some cameras not working due to different pins used for camera reset (which get properly routed in M0188 and M0195 camera adapter boards for the coax cameras).

So i would suggest using the correct kernel 2.0.0, then test one camera at a time and see if you can narrow it down to a camera or port not working.

@Sarika-Sharma ,

The preview width and height parameters are always in the camera config file, so if you added them, they are duplicates (and will be ignored).

Please read through this thread as it has pretty detailed explanation how to configure the correct tof sensor (old or new) for a custom configuration.

Camera-server-config-helper is indeed helpful. If you use it correctly, you should not have to manually modify the resolution in the config file.

If you still cannot get this to work, please let me know what cameras you have plugged in (and which camera ports) on your voxl 2 mini.

@Morten-Nissov Likely should all be off, it's been a while since I've had one of these come across my desk. I'll see if I can find one to reference.

@Alex-Kushleyev Sorry for the delay, didn't notice the alert. But great, thanks!

@Morten-Nissov ,

About the IMU dt, sorry, i got it backwards, the dt is 0.976ms, so that would be slightly above 1khz. So we are on the same page.

Yes, reducing the FIFO size results in more SPI read transactions, which means that the CPU / Kernel has to do more work. There is a per transaction overhead that is much more significant than just getting more data per single transaction.

Let's not bother with the PR because it is a 2-character change 🙂 . I will get to it and test it soon.

@Morten-Nissov I would advise trying to get some support from the PX4 community. I'm not aware of any use of i2c multiplexers in any current PX4 drivers but I think it's a useful feature. But that is the best place to get advice on PX4 development.

@Morten-Nissov , great! You are welcome. Make sure to change that 1us scheduling interval to a more reasonable value 🙂
