@Nitin-Varma-Vegesna If you are just flying in manual or altitude hold modes then those shouldn't be an issue.

@Alex-Kushleyev
Thank you very much for your reply!

We bought the USB C adapter from Flir and followed your guide to enable MIPI. Now it works and I can get the video from the Boson over MIPI.

Thanks for your help!

@Zachary-Lowell-0 thanks.

@minhthinh Documentation for the original VOXL Flight can be found here. The guide will link back to the original VOXL and the original Flight Core as those are the boards it was built around. You can also refer to the release notes of the previous sdks to see what was available in the specific release that you are using

@leandro , documentation for M0187 has been updated to include the 3D CAD file :

@mkriesel , a few tips..

I suspect FETtec ESC is using a pretty accurate xtal or accurate RC oscillator, so you should not need to calibrate the ESC You can check the current calibration by using QGC to control the individual motors to see at which command they start up and make sure that is very close to the same (typically around 1000us or a bit more) Additionally, you can spin up each motor with propeller at certain % power, lets say 20% or 30% and using an optical tachometer (RPM meter) to measure the speed of each motor Those are some sanity checks you can do without being able to calibrate and without having any ESC telemetry.

Regarding the ESC PWM range, the procedure is documented for VOXL2 IO board : https://docs.modalai.com/voxl2-io-user-guide/#how-to-perform-esc-calibration -- please go over that and make sure you did it correctly.

Hi @rpowerscat ,

You may be looking for these?

Hello @namanthaker,

We typically do not provide the register configurations for the cameras because the camera drivers may contain confidential information from other sources.

However, the IMX664 camera is integrated with VOXL2, which can be used for testing and experimentation.

By the way, the camera drivers for VOXL2 are not contained in kernel modules, but in sensormodule binaries, which are loaded by the camera pipeline (just FYI). I am not aware of any way of extracting the register settings from those binaries.

Alex

@voxltester That is not a normal option to choose via voxl-px4.conf. You will need to hand modify the startup script /usr/bin/voxl-px4-start to properly start the driver in i2c mode. Use option -b 4 to select that i2c bus.

@jonathankampia ,

Here is something i tried, you can try as well. You are right, there is a background service that may be taking over, I think i found how to disable it:

systemctl disable QCMAP_ConnectionManagerd systemctl disable qti_pppd systemctl disable qtid rm /lib/systemd/system/multi-user.target.wants/QCMAP_ConnectionManagerd.service rm /lib/systemd/system/multi-user.target.wants/qti_pppd.service rm /lib/systemd/system/multi-user.target.wants/qtid.service #edit: instead of disabling the above 3 services and removing the entries from `multi-user.target.wants`, it seems you can do the following: systemctl mask QCMAP_ConnectionManagerd systemctl mask qti_pppd systemctl mask qtid # you may want to disable dhcpcd as well, but i dont think that is strictly necessary: systemctl disable dhcpcd

Now, set up static connection:

#create a new network interface file vi /etc/systemd/network/10-eth0.network [Match] Name=eth0 [Network] Address=192.168.xx.xx/24 Gateway=192.168.xx.1 DNS=8.8.8.8 1.1.1.1

enable networkd

systemctl enable systemd-networkd

Then reboot voxl2...

I think if dhcpcd is enabled, it may first take over the interface, but then networkd takes it back.. For example, here is the log from networkd when dhcpcd is enabled:

... Dec 10 06:01:00 m0054 systemd-networkd[1126]: dummy0: Gained carrier Dec 10 06:01:00 m0054 systemd-networkd[1126]: dummy0: Gained IPv6LL Dec 10 06:01:11 m0054 systemd-networkd[1126]: eth0: Gained carrier Dec 10 06:02:13 m0054 systemd-networkd[1126]: eth0: Gained IPv6LL Dec 10 06:02:13 m0054 systemd-networkd[1126]: eth0: Configured Dec 10 06:02:13 m0054 systemd-networkd[1126]: docker0: Link UP Dec 10 06:02:21 m0054 systemd-networkd[1126]: eth0: Lost carrier Dec 10 06:02:36 m0054 systemd-networkd[1126]: eth0: Gained carrier Dec 10 06:02:38 m0054 systemd-networkd[1126]: eth0: Gained IPv6LL Dec 10 06:02:38 m0054 systemd-networkd[1126]: eth0: Configured

and the log with dhcpcd disabled:

... Dec 10 06:02:13 m0054 systemd-networkd[1126]: bond0: Link is not managed by us Dec 10 06:02:13 m0054 systemd-networkd[1126]: sit0: Link is not managed by us Dec 10 06:02:14 m0054 systemd-networkd[1126]: eth0: Link UP Dec 10 06:02:38 m0054 systemd-networkd[1126]: eth0: Gained carrier Dec 10 06:09:56 m0054 systemd-networkd[1126]: eth0: Gained IPv6LL Dec 10 06:09:56 m0054 systemd-networkd[1126]: eth0: Configured Dec 10 06:09:56 m0054 systemd-networkd[1126]: docker0: Link UP

Can you try and see if that solves your issue?

I did some additional testing and was able to narrow things down a bit. After reconfiguring the WiFi as a SoftAP using voxl-wifi and then rebooting the VOXL, the network now shows up consistently again. So the broadcast issue seems to be resolved for the moment. However, the core problem remains: I still can’t actually connect to the AP — the connection attempt starts, prompts for the password, and then fails just like before.

If anyone has ideas on what else I could check or has seen similar behavior with this setup, I’d really appreciate the help.
