@zauberflote1 @Cliff-Wong @James-Strawson
guys, can you help me with the error mentioned.
now i have an another error where, if I arm the drone, the vio is drifting, and i can see the values increasing without any movement.
what would cause this kind of errors, earlier the drone was flying fine, then it started drifting, even when just armed.

@Alex-Kushleyev Thank you for reverting back.

@Jetson-Nano VOXL 2 does not have PWM out. You would need our IO expander board M0065 to bridge between UART and PWM. https://www.modalai.com/products/voxl2-io?variant=40610514206771

@Andrew-Martin You can check your camera calibration files with voxl-check-calibration

If you see any missing I can likely locate them and send them over to you

So something that I was seeing while testing this was having a bit of instability with Open VINS flying and altitude flying (Not Using VFC). I was seeing that voxl-open-vins-server stated that the IMU temperature was too high and kept resetting. After letting the VOXL2 cool down for a day I was able to have the Drone Fly in VFC mode but not sure how it flew compared to Position mode using VIO.

@tom i figured it out thank you

@Moderator oh I see, so to reduce overheating would it be recommended to use the default settings instead of limiting my process to cpu 4 to 7?

RESOLVED

for those who come after:

it was indeed an ftdi cable issue. Keep in mind that MCBL-00091-1 USB to Serial UART Cable is not a proper cable (i tried two freshly out of the box, and none worked). Currently using this cable: https://www.amazon.sa/-/en/Moyina-Converter-Terminated-BeagleBone-Minnowboard/dp/B06ZYPLFNB

Hello @Alex-Kushleyev @Eric-Katzfey

I am looking to control the servo via PX4.
Essentially, it will be a command either from the RC or GCS to open / close the servo motor.

But, if that is infeasible, I can make it work via an API on the CPU / Linux on VOXL 2 to be controlled via SSH.

Ashwin

@ashwin This path should be on your host machine, in the modal-qdl repo's directory

@george-kollamkulam

Where are you getting the image / ROS2 packages? Is this an image that ModalAI maintains?

Just looking at the error, it seems like it can't find the yaml-cpp package. It could be that it's not installed correctly or something's wrong in your CMakeLists.txt. It looks like the yaml-cpp readme has some info for including it in your CMake project.

If you're using camera_calibration_parsers from image common, it might be worth bringing the issue up there.

Let me know if that helps,
Ted

@Gary-Holmgren you have saved at least one other person 🙏

@garret Oh, nice! Glad it's working now!

The overall goal is just to get time synced between the Lidar and the VOXL2's IMU. Oddly enough, I was looking through the voxl-kernel for qrb5165 and the driver for PTP is there. Is the physical layer chip not able to support PTP?

Where I see the driver in the Kernel:
https://gitlab.com/voxl-public/system-image-build/qrb5165-kernel/-/tree/qrb5165-ubun1.0-14.1a/drivers/ptp?ref_type=heads

I grabbed the /usr/bin/quectel-CM from another VOXL2 on an older SDK (1.4.1) and swapped out the one that came with 1.5.0 and everything is working again...
