@Kessie Excellent, glad to hear you got it working! And thanks for adding the details on what you had to do to the posting!

@Alex-Kushleyev That was it! I first tried with a lower baud rate of 250K on PX4 and I started getting the battery info. Then as you recommended, I uploaded new parameters to the ESC. I used:

python3 voxl-esc-upload-params.py --params-file ../voxl-esc-params/D0014_starling_1504_3000kv_ms_props/D0014_starling_1504_3000kv_ms_props.xml

because I will be using it on a drone of similar size and performance. Then with 2M baud rate in PX4, I was able to make it work!

Thank you.

@modalab Hello, can you help me to resolve this problem?

The kernel build is posted at https://gitlab.com/voxl-public/system-image-build/voxl-build

@DillonAllen Without WiFi, the only way you'll be able to debug VOXL related things is via. ADB so I would follow this guide: https://docs.modalai.com/setup-adb/ in order to setup ADB on your host computer.

Sorry for the late response, I've been doing some testing. so I've narrowed it down to the error lying in the stereo cameras, I connected each sensor one at a time, reconfigured, and ran the voxl-streamer and was able to get footage for the hires and tracking, but when it came to the stereo it would not work. When I would reboot the system and inspect the services I would see that the voxl-camera-server is running, but once I tried to voxl-streamer -c stereo it would get stuck at the same place and the voxl-camera-server would stop running. I've confirmed that both of my extension cables are working by testing them with the hires camera. I checked the physcial connections on the stereo cameras and there are no creases in them, they look just as they were folded with the original setup, and I believe that if any of the connections were inverted then the VOXL wouldn't even start up.

@Matt-Turi thanks so much!

@Eric-Katzfey Ok thanks for the fast answer.

@Steve-Turner voxl-build allows you to build the kernel only which you can then flash on top of an existing system. Qualcomm licenses are required in order to build a full system image.

@hmlow Glad it worked! For future reference, the imx214_flip driver should be available internally from SDK 1.1 (system image 1.7) onwards. Rather than downloading from the above links, after SDK 1.1 is released the procedure will be as follows:

rm /usr/lib/camera/com.qti.sensormodule.imx214_3.bin cp /usr/share/modalai/chi-cdk/imx214-flip/com.qti.sensormodule.imx214_flip_3.bin /usr/lib/camera

@tom Thank you so much. It is done.

@tom I had the same idea, so I directly installed Mavproxy and related packages on VOXL2, and successfully resolved the issue with the serial library. However, when running the service, I still couldn't import the Python files related to Mavproxy. Even adding the paths of those Python files to the environment variables didn't solve the problem.

@19bpl At the very least you need to be able to ping the QGC computer from VOXL2 and VOXL2 from the QGC computer before attempting anything else.

@Kashish-Garg-0 It's possible your board has a QSM8250 (M0054-2) instead of a QRB5165 (M0054-1), see here for the diffs: https://docs.modalai.com/m0054-versions/#m0054-1-and-m0054-2

If that is the case then you will have to QDL using a different build, which you can download from downloads.modalai.com, look for M0054-2 Starling QDL Image 1.7.4 2024-02-09-1.7.4-M0054-2.zip under the "All" category

@Vinny Thanks for the help on this I really appreciate it. I'll take a look.

@Zachary-Lowell-0

Hello! I was able to reinstall 1.3.5 and that somehow fixed it! I am not going to question it lol.

Now I'm trying to find out how to install voxl-mapper and I can't find documentation for it. I am flying the drone inside a test lab. Today when I was flying it around the room, the drone was not mapping anything. The 2D/3D map was blank when I went to plan a point. I think it's blank because I am missing voxl-mapper especially since I have camera-server, vision hub, voxl-px4 and qvio enabled/running. All I have seen is that I have to change "offboard_mode": "trajectory", in order to plan a point on the map and have the drone fly to it.

Is there any documentation on getting voxl-mapper and planning a point?

@berayksl said in Starling 2 Max Crashes in Position Hold Mode After Disabling Magnetometer for Indoor Flight:

@Cliff-Wong I applied the param file you provided and did some test flights recently. Before the flight, I checked the VIO accuracy by moving the drone around in my hand while monitoring the trajectory in the VIO tab on the portal, and it seemed to be working fine.

During the first flight, I put the drone in “Position Hold” mode. It was holding its position quite well initially. I moved it around and rotated it, and it continued to hold position accurately when I released the sticks.

However, after landing and taking it for another test flight a short while later (same area), it wasn’t able to hold its position well in the z-axis. The drone kept ascending and didn’t respond to RC inputs, so I had to trigger the kill switch for safety.

I noticed that VIO performance seems to vary even when flying in the same area, making it unreliable at times. Additionally, I occasionally get a “Yaw estimate error” message on the portal, but there are no corresponding errors on the QGroundControl terminal, and it still allows me to arm.

Do you have any suggestions on what might be causing:

The inconsistent VIO performance between flights The drone ignoring RC inputs during the second flight The “Yaw estimate error” message (should I be concerned if QGC shows no error)?

I also tried calibrating the cameras (even though I haven’t changed their locations since delivery) by following the link you provided. I was able to calibrate the front camera successfully, but when I try to calibrate the downward-facing camera, the camera feed on the portal becomes extremely laggy, and the calibration app becomes unresponsive after a while, requiring me to reboot the drone each time.

@Eric-Katzfey can you help me with this as @Cliff-Wong was last online 14 days ago?

@Aldo-Castro-Freire thanks for the feedback, do you mind sharing the openVPN Client and Server versions you ended up using that worked?

We've tested using server v2.4.8, voxl-vpn (v2.1.3 inside that), and OpenVPN Connect ver 3.2.2 on Adroid.

Sounds good, thanks!

I reran the calibration outdoors with gps signal and far from any metal. I also raised the drone to be ~3-4' from the metal turntable below it. This improved the calibration quite a bit and the drone is not drifting as much as before. However, there still seems to be more drift in the VIO than there was when I first received the drone. I still don't have the PWM_MIN parameter that the docs say I should check for the assure the PX4 parameters loaded properly. I see that this parameter is in the custom2.params file, but the note in the document says it turns off the gps.

Can you please explain the steps you go through during your calibration process? Should I also be loading this custom2.params file? If so, does that mean that gps is not used when in VIO (no sensor fusion etc)?
