@Eric-Katzfey so I also tried deleting /usr/include/gphoto2, and it still gave the same error. I don't think I had installed gphoto2 separately, but it wasn't a completely clean install. I had to install ROS melodic, and it uninstalled parts of the voxl sdk, and I was trying to reinstall voxl-suite. I don't necessarily need gphoto2, but it's part of what apt tries to install when I run apt install voxl-suite.

Side question: I saw that there was /opt/ros/melodic that came with the voxl image, but there was no setup.bash to source, or is this located elsewhere on the system?

Hi,

I'm having trouble installing the voxl-suite package, due to an error installing the voxl-libgphoto2 package:

Preparing to unpack .../voxl-libgphoto2_0.0.4_arm64.deb ...
Unpacking voxl-libgphoto2 (0.0.4) ...
dpkg: error processing archive /data/voxl-suite-offline-packages/./voxl-libgphoto2_0.0.4_arm64.deb (--unpack):
 trying to overwrite '/usr/include/gphoto2/gphoto2-abilities-list.h', which is also in package libgphoto2-dev:arm64 2.5.16-2
dpkg-deb: error: paste subprocess was killed by signal (Broken pipe)
Errors were encountered while processing:
 /data/voxl-suite-offline-packages/./voxl-libgphoto2_0.0.4_arm64.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

Do you know how I might fix this?

Also, how should mavros (px4.launch) be run with the internal px4 on the voxl2?

What's the best way to install full ROS melodic without all the voxl-suite packages being uninstalled due to dependency conflicts (e.g. opencv)?

@modaltb @Jagatpreet-Singh-Nir

I have a similar issue when trying to connect a USB2/3 camera over the adb port, which was the way I've previously gotten the Voxl1 to run a FLIR Boson camera. The /dev port doesn't show the usual videox port, and lsusb also doesn't show the usb connection, but the camera led light does turn on.

This is also different from the rb5, where I've managed to run two separate USB cameras through the adb port, which I thought would transition smoothly over to the Voxl2. Are there additional steps we need to take to use the adb port as a serial connection for USB cameras, like add dialout group or anything like that?

@Alex-Gardner thanks so much!

So I'm trying to reflash the Voxl2, but the image listed in the docs (https://docs.modalai.com/voxl2-platform-release/#voxl2_platform_121-07) doesn't seem to be available on the downloads page, just 1.1.4. Is this available yet?

We've had issues installing the available system image (1.1.4) with/without the fastboot board, either with fastboot devices showing nothing, or getting an error like:

Edit: Actually, I got the fastboot image flashing to work on one board! But still wondering if this updated image is available, thanks!

@Matt-Turi Thanks! I had tried this one previously, but I'll give it another go with your recommendations.

@Matt-Turi Do you know which of the models the original ssdlite_mobilenet_v2_coco.tflite is from? Could you link to it? We've tried using the conversion instructions from the docs on a variety of the models on the TF1 model zoo (link in the original post), and using TF2.2.3, they still either fail at conversion, get a seg fault with voxl-tflite-server, or they run on CPU instead of GPU, which causes some lag or just causes the Voxl to crash.

@tom thanks! we did put in an order for some, so hopefully I will get those soon. also thanks for the link, I'll check it out!

Separate question: so I have wifi hooked up on an RB5, but everytime I reboot, the ip address changes. Is there a way to change that? It doesn't seem to happen with my voxls (in station).

@tom this is what lsusb shows:
Bus 001 Device 003: ID 7392:b811 Edimax Technology Co., Ltd

@Chad-Sweet I finally got a hold of a wifi dongle from the lab, but it's this one so I'm not sure if it's compatible. So far, it's not lighting up as usual when plugged into the fastboot board (M0078) via the usb-female connector. This dongle usually works with our other ubuntu machines, but maybe we'll have to order some of the supported ones listed on the page. One thing I wanted to ask about that docs page, it mentions under the "rebooting" section that the dongle should now be connected to voxl2 via usb-c. is that typo? I have it connected via the fastboot board and jst-to-usb cable, but the usb-c is being used for adb currently. Also, is there any indicator on the expander board that it's properly plugged into the voxl2?

@Eric-Katzfey Thanks Eric, I look forward to the release! Any update on when that will be?

Hi @Matt-Turi thanks for the information! On M0054/rb5, are you still also limited to tf v2.2.3? Also, can the same GPU/hardware acceleration used in the voxl-tflite-server be done at the docker level? Same question also regarding using the qualcomm neural processing sdk?

Hi, I've been able to run custom mobilenet tflite models via voxl-tflite-server, but when trying to run a Pytorch Yolov5s model ported to tflite, I get the error:

Resolved reporter
ERROR: Didn't find op for builtin opcode 'RESIZE_NEAREST_NEIGHBOR' version '3'

ERROR: Registration failed.

Failed to construct interpreter

It seems like this op is only supported for newer version of TF. Will there be support for this in voxl-tflite-server soon? I noticed the docs say it needs TF<=2.2.3 for now, but I was wondering if this was going to be updated.

I think the conversion produces an ONNX model as an intermediate step- is there a way to run an ONNX model on Voxl1? Alternately, is there a way to run Pytorch models with hardware acceleration? I've tried running CPU models on Pytorch via docker, but keep encountering issues or the board crashing.

Hi, I recently got a hold of a Voxl2, but I don't yet have an internet connection on the board. Is there a way to install packages (similar to ones on the Voxl1, such as docker and ROS) without internet access? Additionally, are the debians on this page for both the RB5 and the Voxl2 interchangebly?

i was able to install the voxl-suite package, but I got this error when trying to install voxl-docker-support:

Is there a way to install docker onto Voxl2 without internet? I wanted to run a docker image I had built for Voxl1 that has ROS/OpenCV and a node for a USB camera. Alternately, is there a debian for ROS that I can install directly on the Voxl2?

@Eric-Katzfey we are trying to do something similar and have been able to connect a Boson through the USB3/adb port. If we still also need to be able to use adb to connect to a computer, can this be done through the USB port on the debug expansion board?

@modaltb I wanted to send an update, I was able to build and run an Ubuntu 18.04 + ROS Melodic docker + OpenCV 4.2.0 (because some of my nodes weren't working on the ROS Kinetic docker), but did require using multi-line arguments as @Voxlady suggested to reduce the size enough to fit. It seems like the size constraints are somewhere around 2.7 GB virtual docker size, and stem from too many docker overlays. Is there anyway around that in case there is a need for larger docker images?

Is there a way to run PX4 flight controller on the VOXL without using the flight core, using the VOXL standalone as the flight controller? That is, could PX4 be run on the VOXL without going through the nuttx system on the flight core (similar to what I think could be done on the Snapdragon Flight)?
