Hi,
If the problem is coming from PX4, how should I go about resolving it? Should I be speaking with PX4 support instead of ModalAi?

Kris

@Chad-Sweet @Adrian-Hidalgo ,
For PX4 confirmation, here is my voxl vision status.

voxl:~$ systemctl status voxl-vision-px4 -l

voxl:~$

Could this be a time/clock, or a watchdog timer issue?

Hi Kris

It looks like the voxl-vision-px4 and voxl-qvio-server versions have gotten out of sync, likely voxl-vision-px4 has been updated but voxl-qvio-server was not.

Do you mind proving the output from the following 3 commands so I can check the state of the opkg package manager

cat /etc/opkg/opkg.conf 
opkg info voxl-vision-px4
opkg info voxl-qvio-server

Thanks,
James

Kris

Hi @James-Strawson , thank you. Here are the outputs you have requested.

Yes, It seems your installed voxl-vision-px4 and libmodal_pipe versions are from SDK 0.8 wheras your voxl-qvio-server is from SDK 0.7, that is the source of the mismatch.

You can upgrade qvio server with opkg install voxl-qvio-server to fix the mismatch quickly but I would recommend just flashing back to the SDK 0.7 platform release since SDK 0.8 does not support TOF on VOXL1. The platform releases are tested as a whole an include a set of packages all known to work together. When individual packages get upgraded instead of the whole SDK together then things tend to break.

Kris

@James-Strawson
Thank you, I will try this

Kris

@James-Strawson could you please help me with flashing back to SDK 0.7 or provide a link explaining how to flash back to a lower SDK?
This can be done over ssh right? Or do I need to ADB into voxl?

James Strawson

Instructions here: https://docs.modalai.com/flash-system-image/

The latest platform release for voxl1 is voxl_platform_3.8.0-0.7.tar available for download here https://developer.modalai.com/asset/1

Kris

@James-Strawson oh ok, now I remember
Cheers mate!

Kris
