@ahmed-mustahid Unfortunately the "QUSB_BULK" mode that your VOXL is enumerating in cannot be fixed by our unbricking process and will have to be sent in for an RMA. See here for info on the RMA process: https://www.modalai.com/pages/rma

Hey @ahmed-mustahid,

To clarify, the image in the gitlab repo is a bit outdated and you will no longer see these red and blue lines in voxl-portal, but rather one black line showing the RRT path.

In terms of not receiving a path, I am unable to reproduce this issue naturally on my end. A trajectory will be shown in the UI as long as a solution is found, and the point you selected should also still be viewable within the map. The second image you shared does not show any of this, and the only way I was able to recreate this was by killing voxl-portal before selecting a point to plan to. Make sure you have an active connection to your drone, the network, and voxl-portal before attempting to use the path-planning capabilities of voxl-mapper.

Hey @ahmed-mustahid,

This is a version mismatch error. The voxl-ceres-solver (v1.14.0-7) package on your voxl is two versions behind what you built against (v1.14.0-9) since you pulled in the latest from dev. When building our packages from source, make sure you use the same repo that your voxl is sourcing packages from via opkg otherwise issues like this will arise.

The partial packet read error usually occurs when there is a version mismatch between packages (i.e. the size of the packet has been updated and one package has the new size but another doesn't). If you update all of your packages together this issue should go away.

In flight you should not have any thermal issues. On the bench please use a fan to cool the device

The OS kills processes when the chip gets too hot. Rebooting should bring it all back

Also, opkg list shows all available versions of packages, so to see what you are actually using you can run opkg list-installed

Hey @ahmed-mustahid,

You can view one camera stream at a time within the Mapper page of voxl-portal.

The bottom left hand corner of the page includes a button (tv icon) to overlay an image stream on top of the map grid. Clicking on this tv icon will populate a list above of all available image topics, similar to the camera dropdown.

Selecting one will overlay it on the page, where it can be resized via the bottom left corner of the stream and closed using the red x at the bottom left.

Hey @jamiek,

If this error occurs, it will result in no map generation at the time of error. This is because we need to grab a pose from our ringbuffer (at the timestamp of our pointcloud) in order to insert each pointcloud correctly into the map.

This is caused by either voxl-qvio-server or voxl-vision-px4 not properly publishing a pose estimate.

You can monitor the output of voxl-qvio-server using voxl-inspect-qvio on voxl or viewing the qvio overlay in voxl-portal. If everything looks good there and qvio is properly publishing pose info, the next place to check is voxl-vision-px4.

This error means that we are not receiving a fixed pose data out of voxl-vision-px4, so once you have verified qvio is not reporting any error codes, monitor the output of voxl-inspect-pose -f on voxl and make sure that you are receiving pose data.

Hi,

You will need to install the openmp package for voxl which can be found here http://voxl-packages.modalai.com/stable/.

The easiest way to do this would be to follow these steps:

Edit the /etc/opkg/opkg.conf file and change the last line from src/gz modalai http://voxl-packages.modalai.com/dists/apq8096/stable/binary-arm64/ to src/gz modalai http://voxl-packages.modalai.com/stable/

Run opkg update

Run opkg install openmp

Redit the /etc/opkg/opkg.conf file to change the last line back to the original i.e. src/gz modalai http://voxl-packages.modalai.com/dists/apq8096/stable/binary-arm64/

Rerun opkg update

Let me know if there are any issues.
