My VOXL2 is stuck in fastboot. I tried to

1. QDL
2. Force fastboot using button on VOXL2 and reflash

Neither of these could get the VOXL2 out of Fastboot. It seemed like something was corrupted on the board (it was the filesystem I believe)

Here are the steps I took to fix it

1. Download the system image from: https://developer.modalai.com/asset
2. unzip the file tar -xzf voxl2_SDK_1.0.0.tar.gz
3. navigate into the file folder, and the "system-image" folder there within cd voxl2_SDK_1.0.0/system-image
4. Factory reset flash using flash-system-image.sh -f
5. You should now see the "Qualcomm-KONA" device, and you should be able to adb in
6. navigate back to the root of the folder "voxl2_SDK_1.0.0"
7. run the install script ./install.sh
8. follow the prompts

You should be good to go from here. I found this information from this other post: https://forum.modalai.com/topic/1931/voxl2-not-coming-out-of-fastboot?_=1698713877796

But thought I would type this up to make it a bit more concise incase anyone came across this same issue in the future

Was curious if voxl-fan was taken out of SDK 1.5

@wilkinsaf

A color AR0144 exists, but there is no current integration readily available

My fault. Found a small tear in the ribbon for the stereo cameras

RESOLVED

@Tamas-Pal-0 This seems like this might be a pid issue. PID issues causes unstable flight making the camera useless since it is all over the place

Would you be able to upload a ulog file to https://review.px4.io/ and post the link here so we can review?

Wanted to update this by saying I experienced same issue, but I resolved this by disconnecting tracking camera that had been installed upside down. So, if anyone is reading this in the future....try disconnecting your cameras attached to the board

It appears this happens when the sensors are not calibrated on the drone. voxl-vision-px4 picks up on sensor inconsistency and restarts PX4.

So, calibrated the sensors. Looks better

resolved

Hello,

We have a UAV we would like to fly indoors and outdoors without landing during that transition.
I know that there is support for EKF2 GPS/VIO "fusion" using 329 as the EKF2_AID_MASK in PX4
Link to tutorial

We were thinking of manually changing the EKF2 bitmask when we fly indoors or outdoors.

My question is, are there any software/features available that would more easily support switching from GPS to VIO? Want to make sure I am not redoing work before I start.

Thank you

@tom Damn.... welp... that would explain what's going on.
Back to the ModalAI store. Thanks for confirmation Tom

@Caleb-Rievley are you loading firmware 1.12 and 1.13 on the VOXL Flight?

ModalAI comes out with their own versions of PX4. Let me dig up that URL:

Flight Core Firmware

ModalAI technical documentation for VOXL and VOXL 2 Companion Computers for PX4 and ArduPilot Obstacle Avoidance and GPS-denied navigation, assembled in the USA

ModalAI Technical Docs (docs.modalai.com)

I think these documentation pages are the same.

https://docs.modalai.com/voxl-cross/
https://docs.modalai.com/voxl-emulator/
https://docs.modalai.com/voxl-emulator/

Not huge deal, but thought I would post ticket to track

Can confirm ordering and installing a new one fixed our issue

@modaltb This worked for me. Removing the USBC cable, booting up, and then plugging in.

@tom

It was a massive lift on my end. Many changes as you can see from the pull request. Years of development

Small update on this. We are still working on the root cause, but one thing that was pointed out by Vinny is we should NOT use a Telit modem on the 5G hat. While the Telit is m.2 form factor, the m.2 standard is not strict. Telit made their own changes that require a different carrier board. So, if you are reading this, and are using a 5G carrier board that only supports Quectel...it means it only supports quectel.

@tom

I threw some code in there to do the operation, but it's pretty much the same as voxl-static-ip

I am just going to go with this patch for right now to continue dev work.

Docker container non-deterministic fail

I am trying to start a container with the following command:
docker run --rm -it --net=host cal_compass:latest

Sometimes it starts right up. Other times it gives me this error: Cannot start container 05621665b072b85b6419f904c0ffb511a1ad07a32c1ca675820aaadbefa4a316: [8] System error: write /sys/fs/cgroup/cpuset/system.slice/cpuset.cpus: invalid argument"

Any ideas what could be wrong? Thank you for any insights

From @tom

Using a VM might be causing a slowdown, but even USB2 vs. USB3 cables can have a pretty big effect on QDL speed.
Suggestion: ensure communicating over USB3

I am also going to attempt to flash from a laptop running ubuntu on bare metal.

Hope to keep this forum post updated with results

RC Passthrough Servo control on VOXL Flight / Flight Core

I should have said "Aux 1 mapped to channel 5 FOR QUAD COPTER LAYOUT" instead of "for VOXL Flight"

but other than that let me know if you have any questions
