@brandon You'll need to load SDK v1.6.x to get it.

@Morten-Nissov you have the kernel variant 2.0.2, which works with M0188 and M0195 camera adapters, but not the adapters you are using. Please update your kernel to use 2.0.0, there are details in a recent question here : https://forum.modalai.com/topic/4975/hardware-configuration-for-2-m0014-tracking-1-m0169-pmd-tof-1-m0024-hires/7

@Sarika-Sharma ,

the screen shot you pasted shows that the second tracking camera has not been found. But above, you mentioned that it is detected. Can you check that?

You can also see which cameras are detected using voxl-camera-server -l to list the cameras and please make sure all 4 cameras are found.

Meanwhile, i wlll test this configuration and get back to you soon.

Hi @cbay ,

I checked with the team - we have not tested using the second lepton plugged into either M0188 or M0195.

The voxl-lepton-server is not set up to handle two sensors. It would have to be the same process managing both sensors because the i2c communication to both would happen over the same i2c bus and the i2c switcher would need to control which sensor is actually being communicated with via i2c.

We have checked that we can control the i2c switcher, but that's about it. We have not needed to use the second lepton (yet).

If you wanted to try it, that would be a risk, but here are the steps:

• plug in and test lepton in primary port
• unplug the primary lepton and plug it into secondary port
• update the voxl-lepton-server to control the i2c switcher to switch the i2c path to second port
• test the lepton plugged into second port
• *** main task *** update the voxl-lepton-server to manage two lepton sensors, switching the i2c communication path, when it is appropriate
  • please note that during normal operation, the i2c communication with lepton is not needed, i believe we only use it if we need to reset the sensor

Hi @Jetson-Nano,

Boson is supported on VOXL2 and VOXL2 mini. See info here : https://docs.modalai.com/M0153/#hardware-requirements

You will need either M0162 or M0181 adapter for plugging Boson into VOXL2 as well as M0201 (which plugs into the back of Boson and provides the coax connector.

What you probably want is the following connection:

[Boson] + [M0201] + [coax cable] + [M0181 J1] -> [VOXL2 J8]

We don't have an out-of-the-box solution for tracking features using Boson. You would need to worry about FFC interrupting the image stream (FFC can be disabled or configured not to run very frequently).

I will find some documentation regarding the feature tracker question.

@Dronodev
ov_overlay is now available under the VIO tab in voxl-portal. Please make sure to update your system to the latest released SDK.

Hi @Pelle-Bredegg-Hermansen
I'll be happy to review your design.

I'll email you now to start the exchange.
Thanks!

Hi @cbay
Sorry, we do not share our PCB design data.

The best we did share is our Breakout Board Design noted here but that is SCH and an Altium Starter Kit w/o libs. Some symbols are in there you can try to export, but not many are in there.
https://docs.modalai.com/expansion-design-guide/#voxl-2-custom-expansion-pcb

And we have this design which we "kinda-sorta" opened a little bit for some schematic guidance.
https://docs.modalai.com/voxl2-dev-test-board/

Hope this helped.

Of note, if you do a board that is meant to mate with VOXL 2 J3/J5 or the camera group connectors J6-J8, I will review your schematic as a courtesy. Just reach out again and tag me, and I can email you privately so you are not posting your design on a public forum.

@sja123 No, unfortunately, we do not currently support boot from SD card.

@magnetocircuit Yes, this is supported. In the config file for px4 /etc/modalai/voxl-px4.conf set ESC=VOXL2_IO_PWM_ESC.
