Hi,
I'm trying to compile/linkage the latest (master branch) voxl-tflite-server code on VOXL2.I'm working with SDK 0.9 .
But during my linkage of the project, i run into the following problems:

Seems like the libcpuinfo.a doesn't include some functions. How it's possible? Thanks for any help.

@Alex-Kushleyev Hi,
Yes,
I want send some new string from VOXL2, that should appear near "FPS:....".
Thanks

Hi,
Could you help me to understand in your voxl-portal source code, how I should modify code for adding in for e.g. in Camera : TFlite tab near "FPS" and "Inference" strings will appear my string "Hello world"?
Please help me. I know, where is a source code of voxl-portal("https://gitlab.com/voxl-public/voxl-sdk/services/voxl-portal").
Thank you for your help.

Hi,

I need to connect my rangefinder (LW20) to the VOXL2 board using connector J19 (by I2C) to the PX4 flight controller. What configurations should I make in QGroundControl to receive the "Distance Sensor" message in the Mavlink Analyze tab?

Thank you.

Re: tflite pipelines sample code

Hi,
Could you point me to a sample code that using tflite\tflite_data as input pipes?
Thanks

@Eric-Katzfey yes

Hi,
After fast rebooting to platform "voxl2_platform_0.9.5",i run into the following problem:

voxl2:~$ systemctl start voxl-px4
**A dependency job for voxl-px4.service failed. See 'journalctl -xe' for details.**
voxl2:~$

From the journalctl -f command after activating the "systemctl start voxl-px4":

Please help to solve the problem.

Hi,
Activating "roslaunch voxl_mpa_to_ros voxl_mpa_to_ros.launch" on VOXL2 is stuck.
Please help me to solve a problem.

I tried to work with the Boson FLIR sensor by connecting it to the M00130 LTE modem board using a USB cable. I activated the voxl-flir-modem. process However, after this activation, the eth0 module got stuck and disappeared from the list of communication devices (there is no eth0 in ifconfig). I connected eth0 using a USB to Ethernet adapter to my PC. Please help me solve this issue. Thanks.
