@david-devassy I'd recommend sending in an RMA: https://www.modalai.com/pages/rma and we'll get things sorted

Hello LaborzaubererTHI, You can see the video now as it has been set as unlisted. https://www.youtube.com/watch?v=jjCKZmrqrVQ Sorry for that. Regards

@Ajay-Bidyarthy Only the inference time should be affected by your choice of hardware. The other two should be the same regardless of your choice. Thomas

@Eric-Katzfey So you probably just need to do the magnetometer calibration procedure to be ready for flight.

@Eric-Katzfey said in Take-Off and Land command each fly to xy=[0,0] location instead of on the spot: @LaborzaubererTHI Sounds like it may be similar to: https://forum.modalai.com/topic/2533/failsafe-landing-bug-in-px4-1-14/19?_=1713800679314 Indeed it does.

@Dawid-Mościcki Perhaps you can ask the QGC development team for some help in narrowing down what is causing QGC to crash. If you think there is a missing parameter then in your /usr/bin/voxl-px4-start script add a new line to touch the parameter so that QGC will see it. (e.g. param touch SDLOG_MODE)

I reflashed firmware and reconfigured drone manually (not using automatic scripts which platform detection) and problem vanished. Probably there is something wrong with detecting actual drone version in those automated scripts.

If any1 will have similar problems in future don't follow guide : https://docs.modalai.com/sentinel-user-guide-pre-flight-setup/ See those docs : https://docs.modalai.com/voxl-elrs/ All You need to do is voxl-elrs -b, then on aperture go to ExpressLRS and choose bind Can be closed.

@Eric-Katzfey thanks mate for your answer!

@Dawid-Mościcki Wow amazing I will give this a try very soon. Thank you so much!

@Alex-Kushleyev Thank you! This worked perfectly, got all of the motors spinning

@enrico-bandera-0 OK got it. You alluded to this, modifying something like hub.c (Generally if it's not showing up, we need to find some flags to add. For example, we added some USB modems like this: https://gitlab.com/voxl-public/system-image-build/meta-voxl2-bsp/-/blob/qrb5165-ubun1.0-14.1a/recipes-kernel/linux-msm/files/patches/005-telit-option.patch https://gitlab.com/voxl-public/system-image-build/meta-voxl2-bsp/-/blob/qrb5165-ubun1.0-14.1a/recipes-kernel/linux-msm/files/patches/004-quectel-usb-wwan.patch ) We'll likely need to find similar for TUSB8041 and then try to add if it's not showing up by default. Are you plugging this TUSB8041 hub into a USB port or using custom hardware? Have you located anything from TI that tells us what flags to enable? That's where I'd go next, see if vendor has clues and then we can try it out.

@wilkinsaf No, they are exactly the same

I will close this ticket and make a new ones. This conversations is too long, sorry for that Thanks for help so far !

@Amin-Bassiri RB5 uses voxl-px4-imu-server . You can verify the IMU data with voxl-inspect-imu imu_px4

@utari_ais Since you're using a voxl1 px4 is running on the flight core not on the voxl itself like voxl2. Therefore there is no voxl-px4 service on voxl1

@tahawaru Here is some documentation on configuring VIO https://docs.modalai.com/flying-with-vio/ PX4 does not currently handle GPS and VIO concurrently. It is something that we have worked with the PX4 developers on for more than 2 years. It's a complicated problem though that we keep working to improve. To start experimenting, and hopefully helping to develop that feature, read through PX4's documentation on EKF2. To debug VIO, look to this area of the documentation specifically https://docs.modalai.com/flying-with-vio/#troubleshooting-vio

I tested AR0144 with M0036 flex in the configuration shown in picture below and it works. I also have the IMX412 camera attached with its own flex. The dual flex configuration is not ideal for plugging into M0135 due to flexes pointing towards each other after being connected to M0135, but for testing purposes it is OK. If you have AR0144 camera connected in the same way with the flex cable and the camera is not detected, then it seems like the flex cable is the issue. [image: 1712797006349-img_3942-resized.jpg]
