@Jetson-Nano , when you view tflite output from voxl-portal, the tflite processing actually starts, which causes a surge in cpu and gpu load, which causes an increased power draw. If the power cable has worn contacts (with increased resistance), the voxl2 board can go in undervoltage condition and reboot. With this in mind, could you please try to replace the power cable and let us know if this solves your issue?

Thank you

Alex

@Jetson-Nano you could just use the CPP mavsdk instance to grab the TOF data from a MPA pipe and then leverage that to do your controls via mavsdk (I am assuming just offboard movement). You can connect over port 14551 just ensure you have localhost comms set to true in voxl-vision-hub.

@Jetson-Nano , 60C is not an issue for embedded devices (throttling limit is around 95C, at which point the CPU will start reducing frequency to avoid overheating).

However, you mention that the temperature can reach 90C. Please note that the camera server itself most likely is not the main cause of the CPU temperature, but the consumers of the image frames may be using significant CPU.

You should identify the main causes of temperature rise by looking at output of top to see rough cpu usage of each process, but also try disabling mapper or openvins or hires image processing (if any).

Also, without any cooling, it is not a surprise that VOXL2 could overheat if its cpu / gpu load is very high. The SoC cannot run without cooling at full power. Airflow during flight usually provides significant cooling and you can manage the system load when not in flight or add cooling for stationary use cases (lack of air flow from propellers),

I am attaching an issue i am facing, the drone is stable in a mat, but as soon as i bring it back i loses the position and drifts out and goes crazy when i try to give pilot input

@Alex-Kushleyev Thank you for reverting, I will check this out and get back to you

@Jetson-Nano , please confirm the ESC is working by using a usb to serial connection directly to the esc and voxl-esc Python tools on a Linux PC or VM.

You can run simple commands to detect the esc and perform spin tests if needed, this is all documented.

https://docs.modalai.com/voxl-escs/faq/

If the esc is ok, then you will need to double check the FC v2 setup.

@Alex-Kushleyev, I using voxl2 with M0173 board with camera config 29.
The errors are now solved, I made the necessary changes and reconfigured every server and pipeline and calibrated the cameras.

@Jetson-Nano We have never used Microhard on windows but it's possible your firewall is blocking UDP data on that port

Hi @Alex-Kushleyev @modaltb @Eric-Katzfey
I still have the same error when i use my custom board. Could you verify my board pinouts.

@Jetson-Nano To install the new voxl-io-server try dpkg --force-all -i voxl-io-server_0.0.5-202502191136_arm64.deb.

@tom thank you for reverting , I sorted out the issue, the file name in the voxl-qvio-server was opencv_tracking_front_intrinsics.yml instead of opencv_tracking_intrinsics.yml
and in the voxl-vision-hub the name was tracking_front which i renamed in tracking. After the above mentioned changed the voxl-qvio-server is working fine.
thank you for the support.

@Jetson-Nano Here's some example code: https://gitlab.com/voxl-public/voxl-sdk/services/voxl-vision-hub/-/blob/master/src/autopilot_monitor.c?ref_type=heads#L514

@Jetson-Nano It should be no different than with any other flight controller hardware running PX4. The PX4 documentation should be able to explain how to do that.

@Alex-Kushleyev @Eric-Katzfey can you check it out and help with the code.

I am also interested what kind of signal is send to the neopixel LEDs to turn it ON.
And with addition to that what is the command to turn ON only blue lights.

@Jetson-Nano , I am sorry, I don't have this hardware set up right now, so I can't actually test what you are trying to do. I will check with the team regarding who can test it.

Alex

Hi @Jetson-Nano
Please see this cable page for more guidance.
https://docs.modalai.com/cable-datasheets/#mcbl-00085
Doodle is one of those applications which we give customers enough to start trying it, but we encourage a custom solution to fit your application(s).
Thanks!

Hi @Jetson-Nano
No difference in data rate on any MH board. They are all USB2 rates.

Hope that helped!
