You may also be able to resolve your issue by switching to voxl-cross:4.0 docker image, which was recently released.

@shivam-rana , you can try to plug your USB adapter into VOXL2's USB expansion board and check dmesg to see if a wlan adapter is detected. If you don't see anything related to wlan or ethernet adapter being connected, then your adapter is not supported. Adding support for 3rd party wifi adapters to VOXL2's kernel would require expert knowledge and experience in building linux kernel modules.

@KnightHawk06 ,

You can use the following trick on VOXL2 to find which package the library belongs to and then build the deb from the installed package. In this case the library is in a proprietary package qti-gbm, which you can easily re-create for use in your docker container. This is related to the following documentation page which describes how to run OpenCL inside a docker container : https://docs.modalai.com/voxl-2-opencl-in-docker/

voxl2-mini:~$ dpkg -S /usr/lib/libgbm.so 
qti-gbm: /usr/lib/libgbm.so

apt install dpkg-repack

voxl2-mini:~$ dpkg-repack qti-gbm
dpkg-repack: warning: unknown information field 'Oe' in input data in entry in dpkg's status file
dpkg-repack: warning: unknown information field 'Packagearch' in input data in entry in dpkg's status file
dpkg-deb: building package 'qti-gbm' in './qti-gbm_18.0.0-rc5_arm64.deb'.

Hi @ysc , please see the following documentation pages:

https://docs.modalai.com/debugging-camera-issues/
https://docs.modalai.com/configure-cameras/#connect-a-new-camera

Your VOXL2 SW is likely set up for different camera configuration and you have a non-standard single camera setup (your IMX412 is connected to J7L, which is camera slot 2).

Considering that voxl-camera-server -l is already detecting your camera, you can confirm that it is IMX412 based on the sensor ID (also in docs above). The i2c read errors are coming from trying to detect cameras which are not physically connected (0x356 is the WHOAMI register value of AR0144 camera, which you do not have connected to your voxl2).

If you look in your /usr/lib/camera/, you should only have an imx412 sensormodule with slot 2 (com.qti.sensormodule.imx412*_2.bin) and if you don't want to see the i2c probe errors, you can remove other sensormodules from that directory (however they should not hurt, since you are already detecting your IMX412 camera, it seems).

You also need to take a look at your /etc/modalai/voxl-camera-server.conf and confirm it is correctly set up for a single hires imx412 camera. Then run voxl-camera-server in foreground to see any error messages.

@brendan424 , please check the following Q/A and let me know what you find about your LED behavior. Please note that after the initial few flashes, the blue LEDs on the ESC turn off until the flight controller (VOXL2) starts communicating with the ESC. Therefore, I do not fully understand your statement " turns on with lights when connected to battery power, but when I plug in the voxl esc cable, lights shut off". Are you able to make a video or describe more specifically what LED behavior is before you connect your cable to VOXL2?

https://docs.modalai.com/voxl-escs/faq/#unboxing-and-testing-new-standalone-esc

Also, what cable are you using to connect between VOXL2 and the ESC (what is the cable part number, which should be marked on the cable)? Where on VOXL2 are you connecting the cable? Does the same cable work with another ESC? How do you test?

Alex

@claw That is definitely not the expected behavior, I recommend going through the RMA process

@claw I would try installing the SDK with ./install.sh -w to wipe all partitions and start fresh.

If that doesn't work it may be worth submitting an RMA: https://www.modalai.com/pages/rma

@will-huang-oksi That post also refers to using mavlink router. Have you tried that?

@claw Are you running Ubuntu natively? If so, what version?
