@arcj can you share your working tflite configuration with M0014 and the configuration that is not working with M0025?

Hi @Alex-Kushleyev ,
Thank you for your suggestion. Now I understood. how to use my existing stereo, and tracking cameras on voxel-2.

@perfx I'd recommend reaching out to Ascend Engineering, they're ModalAI product experts and they'll be able to help you out: https://www.ascendengineer.com/

@daniel-p-nikolov said in Issue recognizing camera MSU-0107 using M0135 dual camera board:

Tried various setups, however, it does not see any camera connected to the VOXL2.

@daniel-p-nikolov I would recommend doing a custom camera config setup. What you can do here is run voxl-configure-cameras C and then vim into /data/modalai/custom_camera_config.txt and then proceed to edit the file for this port and position - so in this case it would be

J7 lower info is hires, imx412, and false.

Then proceed to rerun voxl-configure-cameras C again and then rerun voxl-camera-server and see if cameras are detected. There could be a mismatch occuring of the port and such when using the non custom script.

@Chase-Riley the recommended approach is to use J18 ESC port directly: https://docs.modalai.com/voxl2-external-flight-controller/#voxl-2-connecting-an-external-flight-controller

Hi @Chase-Riley
Your best bet might be to start a new thread, that will help ensure you get more eyes on it for the best person on our side to help you along!
Thanks!

@Eric-Katzfey Yes the Mavlink Packets will be sent form PX4 running on the VOXL2 through the Trip Module and then to the Doodle, and vice versa for the data flow from the GCS to PX4.

My understanding is that the Trip is just running a extension of Mavlink to allow for specific gimbal and camera commands. Also it is performing Video compression.

@Vinny Thank you for your info. I will review with my team and see if it makes sense for us to pursuit that direction/option.

Best Regards,

Hi @cobbp
It's the 2.96V directly from the Snapdragon PMIC as you noted, and SD Cards from UHS I and onward negotiate their link speeds and I/O voltage. So, a proper 1.8V SD card will internally use that 2.96V and create the 1.8V I/O rail.
For cards that operate at "3.3V", they are claimed to be supported in the Snapdragon chipsets at this lowered ~3V rail.
The slot on M0062 actually accepts UFS or uSD.

For more details on just the SD portion, please see this design where we opened our Schematics. In this case, this is just uSD, but otherwise matches the M0062 exactly for uSD functionality: https://docs.modalai.com/voxl2-dev-test-board/

Hope this helps!

@Peter-Milani Nothing available for the public just yet but I can tell you we're working extremely hard on this and hope to start publishing builds soon

@voxl-phoenix J19 has pins for 2 UARTs. We put GNSS on one and RC on the other. So if you are able to hook up everything correctly, configure the TBS crossfire receiver correctly, and configure PX4 correctly then it should work.

@jklre , one way to achieve what you need is to set up a VPN client on VOXL2 (and VPN server on your linux server) and create a adb TCP bridge via adb forward or reverse (which you already found). Your VPN client would connect to the VPN server on your linux server via the ADB TCP tunnel.

The VPN client / server would then take care of proper data routing (just like regular VPN).

I believe guys from Ascend Engineering were able to to achieve this : https://ascend-engineering.gitbook.io/modalai/sharing-internet-over-adb but it requires initial internet connection to set up.

Your best bet may be to get all the dependencies downloaded to your linux server, then push them to voxl2 via ADB, and add a local package source for apt on voxl2 (so that it can find new packages) and install.

Similarly for python modules, you should be able to do an offline install, i think..

@Achyut-Sapariya That all looks normal, I'd recommend submitting an RMA and our team can diagnose the issue: https://www.modalai.com/pages/rma

@rogerli or @McMason Were either of you successful in getting the VOXL2 to connect to the NV Trip2? Working the same issue on my end.

Hi @Alex-Kushleyev ,
Thank you very much for such a detailed reply, we will carefully refer to your suggestions to make the purchase.

thanks again!

@Dhatchayani-L It appears that your board is booting into QUSB_BULK mode, which will require following the unbricking process to resolve:
https://docs.modalai.com/voxl2-unbricking/#unbricking-your-voxl-2

@Gary-Holmgren , oh yeah, I almost forgot about the issue of not being able to use the DSP uart ports while PX4 is running.. 🙂

To work around that, you could potentially connect M0065 board to one of the UART ports that are actually connected to CPU and access it directly from linux use /dev/ttyHSx devices

You can find the linux uart ports here : https://docs.modalai.com/voxl2-linux-user-guide/#uarts - you will need an expansion board, but even something like M0141 or M0151 will do (which is probably the simplest).

However, it sounds like maybe you are close to figuring out he pwm output via px4, so perhaps this is not needed, but you can keep it in mind.

@smilon we're still working on it but slower than I had originally planned. we're using it on a feature light product right now without camera support, once we have camera support in place I'll try to get some preview releases in place, 'hoping' that's in Q1/Q2 but as an optimistic engineer speaking 😉
