Sony RXO over USB

@Matt-Goddard We have two different implementations for gphoto2 on VOXL. voxl-libgphoto2 which is what you are using and we also have voxl-gphoto2 which is a newer version that also uses voxl-streamer. I think I will have you try voxl-gphoto2 now.

Here is the link to the build/install instructions for the newer gphoto2 implementation.

Here is a link to the documentation

You will need to use this in combination with voxl-streamer and here is some documentation for getting that going.

[Matt Goddard]

I will try this now and get back to you. Thanks!

[Matt Goddard]

During the process, we managed to brick the board. Will not boot now..

[tom]

@Matt-Goddard We have some documentation on unbricking here

[Matt Goddard]

Got it, we will order the part and unbrick lol. Thanks for the help!

[Aaron Bottke]

The USB and Serial Debug board arrived today. I unbricked the board and installed gphoto2 and VOXL-streamer. The image below is an error I received after running the voxl-gphoto2 command.

Please advise.

Have you tried gphoto2 using a Linux machine to make sure this device is supported?

Sony RXO

The RX0 II is on the list, is that what you're using?

[Aaron Bottke]

Yes we are attempting to use the RX0. The image below shows that gphoto2 does detect it on an ubuntu machine.

[Eric Katzfey]

@Aaron-Bottke What happens when you run gphoto2 --capture-preview? Do you get an image?

[Eric Katzfey]

@Aaron-Bottke Also, can you try running voxl-gphoto2 with debugging information enabled and send us the ouput? For example: voxl-gphoto2 -d -v -g

[Aaron Bottke]

Results of gphoto2 --capture-preview on my host machine as follows.

On the VOXL running voxl-gphoto2 -d -v -g yields way to much for me to share here so I will split it up.

voxl-gphoto2 -d below.

voxl-gphoto2 -v yields a lot of messages very quickly.
Output as follows.

voxl-gphoto2 -v yields too many messages for me to upload with a screenshot.
I don't see a way to submit a .txt file but the most interesting part of the output that I see is this.

[Eric Katzfey]

@Aaron-Bottke Okay, thanks! That's very helpful information. It looks like the camera is producing images and voxl-gphoto2 is processing them correctly. So try voxl-streamer and see if you can stream the video. That error message seems to be coming from the gphoto2 library but doesn't seem to be hurting anything.

[Aaron Bottke]

Unless I am missing something in the command this is the result from running voxl-streamer and voxl-gphoto2.

Thanks for all the help.

[Eric Katzfey]

@Aaron-Bottke Documentation on voxl-streamer is here: https://docs.modalai.com/voxl-streamer/

For gphoto2 you will want to look at the gphoto2-mpa configuration in /etc/modalai/voxl-streamer.conf. You can use this configuration record by launching with voxl-streamer -c gphoto2-mpa

[Aaron Bottke]

That got it working!!! I really appreciate the help with this!!!
My telemetry quit working though so I have to play with that and get that up and running again.
Thanks!

@Eric-Katzfey

The gphoto-2 seams to be breaking the voxl-vision-px4 system. Any command associated with the voxl-vision-px4 system causes the voxl to kick any adb connection then prevent any from connecting until a power cycle. I can't get both voxl-vision-px4 and gphoto2 installed and running on the same system.

Any thoughts?
Thanks,

[Eric Katzfey]

@Aaron-Bottke I'll take a look

[Eric Katzfey]

@Aaron-Bottke I did a fresh install of system image 3.2.0 without installing any additional packages (voxl-suite). After setting up WiFi to connect to the Internet I ran these steps on voxl (over adb):

• opkg update
• opkg install voxl-vision-px4
• voxl-configure-vision-px4 (Specifying no cameras)
• Verify QGC connection with telemetry
• opkg install voxl-gphoto2
• opkg install voxl-streamer
• voxl-gphoto2
• voxl-streamer -c gphoto2-mpa

I then see both telemetry and video in QGC.

[Aaron Bottke]

@Eric-Katzfey
Not installing the voxl-suite at first and using opkg to install gphoto2 and voxl-streamer worked.
Before I was following the instructions and compiling my own ipk then loading them on using adb. I've got both a video stream and telemetry over the Microhard Modem!
Thanks,
