  Just making sure you have seen the relevant documentation here It points to the VIO parameters helper file here. Specifically the EKF2_AID_MASK is often overlooked as an important parameter.

  We don't sell any platforms with the M0024 sensor onboard by default. If you're just trying to use it for color fpv/more general inspection I'd suggest just VHB taping it to the front, if you're trying to use it for hyper-accurate detections you'll have to modify one of our platforms or design your own (as most of our platforms are meant to serve as reference designs and not full production hardware).

  @colerose Yes, the new version fixes this issue and should no longer be a problem. The new output pipe is not compatible with voxl_mpa_to_ros yet, but it will be added in very soon!

  In theory two VOXLs networked together are possible. We have not actually done that ourselves though. You could potentially use the UART side port to send data back and forth with libvoxl_io, that might be the most straightforward.

  Great to hear! Feel free to create a pull request if you would like to get the feature into the mainline so you don't need to maintain a fork.

  Those are the specs from the vendor, we don't have any more information, sorry. The intensity image is published in MPA so you could perform a calibration on it to find out more details.

  @Chad-Sweet how many ekf_imu instances would you suggest running on a VOXL-FLIGHT in general, considering a decent workload already on the VOXL -part? cheers

  We got it to work by just navigating to the launch file and invoking the roslaunch command from there (and excluding the package name): roslaunch voxl_mpa_to_ros.launch. Thanks, @Alex-Gardner!

  Hi Parisa, A number of the gnu standard tools are defined explicitly to our architecture on voxl: arm-oemllib32-linux-gnueabi. If you tab out that (or just tab out "arm") you'll see a number of the standard tools like gcc, gdb, ld, objdump, etc. To run gdb on voxl would thus be arm-oemllib32-linux-gnueabi-gdb

  Thank your for your reply. The command is pip3 install opencv-contrib-python-headless (=title of the question). Ubuntu docker is a good but not enough . I need this (opencv python package) on the target board, again like supported by modalai's python numpy package. Please help me to create/ download/install this python package on a voxl board. I need it for later using as ROS node (written in python)

  If there are not a lot of file operations, it is pretty rare. It can happen during development as folks are making changes on the board and then pulling power. Linux has a setting for how often the flash is committed to reduce the risk, but of course there could be different side effects. You can see a writeup on the topic here, as it is common in all of this type of single board computers Your smartphone fixes this by making you press the poweroff button before shutting off power.

  The Qualcomm Flight RB5 5G is our flagship 5G product at the moment. We do expect VOXL to support 5G directly by the end of CY '21 with a new add-on.

  @modaltb Thank you for the confirmation on the USB cable. Yes, I am using Ubuntu Virtual Box. The board was communicating fine with the Virtual Box previously (Before bricked) so unbricking on that only. I will try it on another machine as well.

  Hey @colerose, What was the voxl-streamer output when you tried to start the second stream? I was able to successfully start a stream with both the hires and tflite-overlay cameras, however voxl-streamer is very resource intensive when we have multiple streams running. Have you considered using voxl-portal to view both?

  It looks like your machine does not have QEMU support or is missing ARM support on your host machine. Please try instructions here : https://www.stereolabs.com/docs/docker/building-arm-container-on-x86/ (which also show you how to run ARM64 docker images on x86)

  Actually, I don't think it's possible because two identical PMD sensors will have the same I2C ids and communication will interfere. All cameras, with the exception of right stereo (if stereo flex is used) are communicating on the same (primary) i2c bus. The right stereo camera uses the secondary i2c bus. If it were possible to change the I2C id of the PMD sensor, then it could work, but I am not sure if that's an option.
