@voxl-phoenix , this may be a hardware issue because VOXL2 will boot just fine without M0173 camera front end plugged in (if the hardware is OK). It is possible that one of the camera connectors (where M0173 plugs in) has broken off or is loose, causing a hardware failure. If you would like a better diagnosis, please share a video of the voxl2 not booting, so we can see the LEDs (i realize there are green leds on top and bottom, but the way your image shows, you can see both of them. Also, in this non-booting state, does the VOXL2 show up as any USB device when plugged into a linux machine using the main USB C connector?

@Dronodev Using the M0065 on a UART on the WiFi add-on board may be the most straightforward way to do this. We've never tried to set one up like that but, in theory, it should work if configured correctly in px4. There is no direct way right now to send the RC channel PWM input out the VOXL esc PWM output. There are a number of different ways to approach that so we'll take a look and see if we can come up with something in the next couple of weeks.

@tom Thank you!
I am adding an imx214 on J8L.

@jacob-yaacubov We have some add-on boards that would allow connection of 2 USB cameras. For example: https://www.modalai.com/collections/voxl-2-add-ons/products/voxl-microhard-modem-usb-hub and https://www.modalai.com/collections/voxl-2-add-ons/products/voxl-lte?variant=32449203601459

@Eric-Katzfey Thank you! I now use journalctl and write to a file in a logger service, for example:

voxl-mapper-logger.service

[Unit] Description=Logs voxl-mapper log output to file After=voxl-wait-for-fs.service network.target network-online.target Requires=voxl-wait-for-fs.service network.target network-online.target voxl-mapper.service [Service] Type=simple ExecStart=/bin/bash -c "sleep 45 && journalctl -f -u voxl-mapper.service >> /data/logs/voxl_mapper.log" StartLimitInterval=0 Restart=always RestartSec=2s [Install] WantedBy=multi-user.target

@Alex-Kushleyev thank you so much. I can wait till the changes are merged and available to update directly on the voxl2.

Yes, I am using the IMX412 camera.

I can start off with whatever you have got for now and hope for a good video feed on my drone without any gimbal. As new changes come along, I will update.

I have never setup a build environment for voxl repos. I am used to building PX4 etc. with some of my custom changes. I would love to learn how to setup the build environment for the voxl repos. So if you can point me in the right direction, that would be great! I see in the docs, under "voxl SDK > custom voxl applications", there are some instructions.

Thank you!

@kestrelsystemsbp Take a look at Python MPA interface: https://gitlab.com/voxl-public/voxl-sdk/core-libs/libmodal-pipe/-/tree/dev/python?ref_type=heads

@swickliff Interesting, have you had success with this hardware setup before?
