@psafi Here are the steps I am taking for camera calibration:
1- run the following command:
voxl-calibrate-camera tracking_down -f -s 6x9 -l 0.022
2- look at the overlay in portal (see the screenshot below)
3- calibration process is not progressing automatically even though it seems like the checkerboard is detected
I am trying to set up VIO for a custom frame which has two ar0144 (down and front) cameras.
I have followed this sequence so far:
1- voxl-camera-serveris up and running and I can see both camera feed in portal and using voxl-inspect-cam
2- saved Extrinsics to /etc/modal/extrinsics.conf
3- made sure vio_cams.conf exists and information makes sense
4- following instructions as outlined here: https://docs.modalai.com/open-vins/ (with the exception of my SDK version which in my case is 1.5.0)
here is the default content of voxl-open-vins-server.conf:
/**
* This file contains configuration that's specific to voxl-open-vins-server.

5- I see voxl-open-vins-server process is not running and when I try to run it manually I get the following warning/error:
WARNING: cal file opencv_tracking_front_intrinsics.yml is missing or invalid
run voxl-check-calibration to see what calibration files are missing

Camera shutdown complete
error code: -1
I am currently in the process of calibrating the camera but I am unable to complete it. I can see the overlay in the portal and all corners being detected but calibration is not progressing beyond %0
@psafi UPDATE: I re-flashed the SDK and it fixed it. voxl-camera-server is running and cameras are working. I am setting up VIO for a custom system. I believe a change I made along the way for VIO set up process could have caused this.

I am seeing a pattern which voxl-camera-server will crash every time I have an image sensor plugged into a specific port (J6) on my VOXL. Could I have accidentally damaged hardware by plugging in the adapter board the wrong way?
@Alex-Kushleyev Ok great. Thanks.
One more question, to configure VIO/QVIO for a custom frame with a single (downward) camera, how should I go about following the documentations?
I am starting with https://docs.modalai.com/open-vins/
However I came across this:
"This documentaion will assume that there are some steps that have already be taken. ...Assuming that we are working with between two and three camera tracking."
are there different procedures for a system with single camera? Also a high-level roadmap on how to go about configuring VIO/QVIO for a custom frame would be appreciated in case information is in multiple places in documentation. Thank you for your support.
@Alex-Kushleyev This is all great information. Thank you. We will continue tuning the motors using the utilities provided.
On a separate note, I did not see the html report file in the voxl-esc-tools directory or other directories I looked at. Where do they get exported to?
@Alex-Kushleyev Thank you. This is helpful.
What is QVIO as opposed to VIO? My goal is to set up VIO on a custom quadcopter frame and I am following these instructions. I don't see any mention of qvio
Hello,
we are trying to calibrate a m0138 ESC using a VOXL2 mini. We have upgraded the ESC firmware using the provided scripts. We were able to run the script on m0 successfully and motors spun all the way to the max rpm set in the config file (see attached log). However, the calibration failed to spin the motors all the way up to the max pwm value for second motor (it keeps resetting to 0 , ramps up again and never exceeds about %15-20). attached is output log of the failed test as well.
we also tested a version which we updated the number of poles and kv to match our actuators and we seemed to experience similar issue.
Below are some of printouts of the python scripts and also specifications for the actuator we are using:

what kind of dimensional tolerances are acceptable when configuring the extrinsics for VIO when building a custom vehicle?
@psafi said in GPIO missing in /sys/class/gpio:
@Alex-Kushleyev Thank you!
I understand these ports are intended for RC input and QUP7 is connected directly to the DSP. I am considering these ports to connect a SiK radio (data format can be raw or mavlink). I want to make information coming through the radio available to ROS and PX4 at the same time. Can I use this port at all for application running on linux or is this only available to voxl-px4?
I am already using the External UART (J10) for another MAVLink device (optical flow sensor board) which is currently configured and working with PX4 (I don't need to intercept that one on the linux side). Would it be possible to connect my serial radio to J10 and switch my optical flow to J19 (and configure PX4 to read MAVLink from J19-10,11)?

I don't see GPIO 178 and 179 on my system:
@Eric-Katzfey I did the systemctl stop and started service again. I guess rebooting the board earlier did not have the same effect. The compass calibration in Q is working now (no more "no mag found" error) which I guess it means the mag is working now and our gps is working too.
here is the output of voxl-p4 -d by the way:

@Eric-Katzfey by installing debian package and I got output similar to this after installation:
https://gitlab.com/voxl-public/voxl-sdk/services/voxl-px4#deployment
@Eric-Katzfey I did that and was able to build and install new px4. Thank you!
Sill not detecting lis3mdl module on the px4 side.
I tried adding the following to /usr/bin/voxl-px4-start
qshell lis3mdl start -R 10 -X -b 1
but I think that causes px4 service fail to start. Not sure if that means the module has not been successfully added to voxl-px4 or some other issue.
Are there any steps I need to take besides adding sensor name to default.px4board file?
@Eric-Katzfey I am able to build voxl-px4 now.
I am following instructions outlined here to add this magnetometer:
https://forum.modalai.com/post/16770
I am adding following line:
CONFIG_DRIVERS_MAGNETOMETER_LIS3MDL=y
to this file:
https://github.com/modalai/px4-firmware/blob/voxl-dev/boards/modalai/voxl2-slpi/default.px4board
when I attempt to build px4 I get the following error from the driver module:
@Eric-Katzfey Ok great. This is working now. It would be great if you can give me some idea of the underlying architecture for troubleshooting in the future and also making sure this is not going to have any side effects on the entire system. What is the role of voxl-mavlink-server in all of this? I understand we are telling voxl-px4 to expect mavlink messages on ttyHS0.
I see messages 132 and 106 start showing up in output of "mavlink-server -k" which is "show debug info on messages coming from autopilot" and they stop showing up when I unplug the sensor. It'd be great if you can give me some idea of flow of information.
