voxl-docker-mavsdk-python build issues
-
@Alexander-Saunders can you try the following patch to the Dockerfile?
I noticed that the mavsdk 3rd party package updated their header files to include a filesystem header that is incompatible with standard cpp libraries on ubuntu 18.04, hence switching the dockerfile to focal instead of bionic. You can save the text in a *.patch file (e.g. "filesystem.patch") and then run
git apply filesystem.patchAlternatively just switch the docker base image from "bionic" to "focal"

@brahim Thank you for getting back to me! I do not have access to the VOXL at this moment, but will be able to test first thing in the morning.

@brahim Changing from bionic to focal lead to Docker being installed successfully. I am currently following this documentation: https://docs.modalai.com/voxl2-PX4-hitl/ .
The commands were ran fine:
1. wget https://storage.googleapis.com/modalai_public/modal_dockers/voxl-gazebo-docker_v1_2.tgz 2. docker load < voxl-gazebo-docker_v1_2.tgz 3. docker tag voxl-gazebo-docker:v1.2 voxl-gazebo-docker:latestI am not using QGC because I am troubleshooting why only heartbeat packages are being sent and not GPS, Odometry, etc. voxl-px4 and qvio-server have been disabled.
In a separate terminal, voxl-px4-hitl is being ran as called for in the documentation. The main issues are gazebo seems to not give expected outputs with some of the commands and the lack of status data from dsp_hitl. I've also looked through the forum to see if anyone else had a similar problem. If you or anyone could point me in the correct direction, I would greatly appreciate that!

@Alexander-Saunders @brahim to add on a follow up, what is the correct pin out of the FTDI cable we plug into the j18 port? Documentation says no power, just RX, TX, and Gnd; but YouTube instruction by Ascend Engineering uses Power as well. YouTube video by ModalAI matches instructions but the information doesn’t seem to be read, just heartbeat packets.

Hi @Stefan-Amundarain
Not all FTDI cables are the same. There are literally over a dozen variations out there.
If the specific FTDI cable requires a "VTREF" to set the logic levels, then a VCC is needed as on Ascend's example. If you use one that is USB powered and TTL levles, then likely it is already set for 3.3V, and no power is required.
So, please double check your specific FTDI cable before following any tutorials you may see and make appropriate mods as needed.Thanks!

@Vinny @brahim @Eric-Katzfey We're still running into the issue of no meaningful data being sent to gazebo. The only data is still the heartbeat packets.
We're referencing: https://docs.modalai.com/voxl2-PX4-hitl/We've done the steps up to: docker run --rm -it --net=host --privileged -e DISPLAY=$DISPLAY -v /dev/input:/dev/input:rw -v /tmp/.X11-unix:/tmp/.X11-unix:ro voxl-gazebo-docker ./run_gazebo.bash
and
qshell dsp_hitl status which is telling us about the heartbeat only.
Also, we tried the archived instructions to see if we would get a different output.
The FTDI cable used is the same, but the serial port closed issue has stopped. Don't know why.
The warning for SDF I feel like is the source of the problem.
The warning when running docker run --rm:

@Alexander-Saunders Are you doing
xhost +before running docker? -
@Eric-Katzfey The latest attempts, yes. After running that and
docker run --rm -it --net=host --privileged -e DISPLAY=$DISPLAY -v /dev/input:/dev/input:rw -v /tmp/.X11-unix:/tmp/.X11-unix:ro voxl-gazebo-docker ./run_gazebo.bashgazebo will open up. The issue is connect gazebo with VOXL2 to run in HITL mode. I've followed two of the video from Modalai and Ascend exactly with no luck. Also went through the documentation again.
All instances are being ran on the host computer. When comparing the image from above to docs, we are only getting heartbeat packets.
-
@Alexander-Saunders The heartbeat counter is the amount of heartbeat messages being sent out, not received. So you are not getting anything on the serial port.

@Alexander-Saunders Definitely looks like a permissions issue of some sort in your system.
-
@Eric-Katzfey Are you suggesting giving the file/repo permissions with
xhost si:localuser:rootAlso we are using the FDTI cable provided with the ESC AND USB C to A to connect to host.
-
@Alexander-Saunders I'm only suggesting that there is a permissions problem of some sort. I don't see that on my machine so just trying to figure out what is different in your environment.
-
@Eric-Katzfey I tried giving permission to user with no change.
-
@Eric-Katzfey Is it possible to see a picture of your terminal of the commands you sent?

-
@Alexander-Saunders iris_hitl.sdf is part of the docker image so it will be the same.

@Alexander-Saunders We have quite a few customers using HITL successfully and they are using the instructions in the document so I'm thinking there is something in your environment that is causing the issue. Do you have access to a different Linux machine that you can use?
