@Eric-Katzfey I would love to contribute!

I tried setting up voxl-cross. The pre-build version of voxl-cross is v2.7 on the downloads page. But I see that the voxl-cross in the repository has reached even v4. So I wanted to build voxl-cross myself. Unfortunately, the instructions say to download these files from the modalai downloads:

ubun1.0_1.8.04-M0054-14.1a-perf-20250421-rootfs.tar.tar
ubun2.0_2.0.0-perf-20250421-rootfs.tar.tar

And I can't seem to find these files. Without that, I am unable to compile. Any suggestions on how to compile the latest voxl-cross? Or should I just use v2.7?

Thanks.

Re: External MAVLink Connection using VOXL 2 through ttyHS1

Hi,

I am in need of integrating a mavlink gimbal and a parachute with the voxl2 autopilot. Mavlink is becoming a common protocol to communicate with a number of external peripherals like gimbal, parachute, engines etc. As such, there is a growing need to have voxl-mavlink-server be able to start a bi-directional mavlink stream on app UARTs like that on the USB3/UART Add on board (/dev/ttyHS1).

Is this something on the roadmap? Or any work arounds at the moment?

Thanks.

@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!

@Alex-Kushleyev said in EIS merge:

You will need to build the voxl-camera-server and voxl-portal packages from the appropriate branches. Hopefully you can do that by yourself. If not, i can post the test debs.

Hi @Alex-Kushleyev I want to use the EIS features. Would you be able to help me guide in the right direction of how to setup a build environment and build from the voxl-camera-server eis branch? Thank you.

@Alex-Kushleyev That was it! I first tried with a lower baud rate of 250K on PX4 and I started getting the battery info. Then as you recommended, I uploaded new parameters to the ESC. I used:

python3 voxl-esc-upload-params.py --params-file ../voxl-esc-params/D0014_starling_1504_3000kv_ms_props/D0014_starling_1504_3000kv_ms_props.xml

because I will be using it on a drone of similar size and performance. Then with 2M baud rate in PX4, I was able to make it work!

Thank you.

@Alex-Kushleyev No, it was default. I am using the latest QGround Control. Here are some images of the parameters.

All voxl related parameters:

VOXL_ESC_PUB_BST:

I also double checked using manual entry:

Let me know if that helps.

@Eric-Katzfey VOXL_ESC_PUB_BST = Enabled and px4-listener battery_status gives "never published".

@Alex-Kushleyev Thank you for your reply. I want to set up a single IMX412 camera (with same settings to start with) for live video streaming. I also want EIS and found a recent topic with your comments which I will follow.

For initial testing, I will be using the Starling 2 Adapter M0173 with one IMX412 camera. Once I purchase the single adapter (MDK-M0155-1), then I will use that instead.

I will try out what you proposed. Will reach out if there are any issues

Thank you.

Regards.

Hi all,

I currently have the Starling 2 Adapter M0173 with C29 config (dual IMX412, TOF, dual AR0144. I am able to configure the cameras using voxl-configure-cameras, and see all the four video feeds in the voxl portal.

I now want to create a custom configuration with Micro-coax Adapter (MDK-M0155-1) and single IMX412 camera. I see that I need to create a custom configuration file before running the voxl-configure-cameras command but I don't know how to do this pls.

Can someone help me to setup a single camera feed as mentioned above.

Thanks.

@Alex-Kushleyev the RX and TX lines need to be swapped at the J18 connector as well, please
