Hi,
I connected Lightware LW20/C on one of the I2C port on VOXL2 J19.
It is QUP3, and the pins I used are

7	I2C3 SDA 3P3V	slpi_proc, SSC_QUP3
8	I2C3 SCL 3P3V	slpi_proc, SSC_QUP3

and power & ground.
I also installed a customized voxl-px4 which will start lightware_laser_i2c with the I2C address 0x66.
On VOXL2, I edited voxl-px4.conf file by adding DISTANCE_SENSOR=LIGHTWARE_SF000.
However, I cannot see any parameter regarding rangefinder... like SENS_EN_SF1XX.

I have done using LW20/C with UART connection successfully, but I2C does not work..
Can anyone give me any advise to use it via I2C?

I see. If VOXL2 is connected to a local laptop that has internet access, but VOXL2 itself does not have internet access, will VOXL2 update its date and time through the laptop?

Hi,
I am wondering when the time sync function is updated on VOXL2?
When I run date on VOXL2, it shows the old time when the SDK developed.
But this time, after upgrading the SDK, it is showing the current time!
How is it working?

Thank you.

This is totally the power cable problem...
Is there any future plan to make it stable?
It is horrible to imagine the drone crashing due to a reboot issue caused by the power cable.....

@Vinny

I will have a look.

This is very randomly happening...
I changed power source (battery, wall power), but it is working well now...

Is there any way to check GPU usage on VOXL2?

@Vinny

I have the rebooting issue with a VOXL2 flight deck with Microhard radio.

I have tested with 5G board (M0090-3-01) as well. I connected a USB3 ethernet adapter on the 5G board to communicate with my laptop through ethernet cable. The same issue happened.

When I directly powered the system by using a power supply (5V) without a power module, it did not show any rebooting issue....
I am still figuring out, so please let me know what I need to try...

@Alex-Kushleyev
Thanks for the information. What kind of USB3 add-on will work for this?

@Alex-Kushleyev nothing detected.

I am following https://docs.modalai.com/voxl2-usb3-uart-add-on-user-guide/
I have a samsung usb storage (https://www.samsung.com/us/computing/memory-storage/usb-flash-drives/usb-3-0-flash-drive-bar-32gb-muf-32ba-muf-32ba-am/)

formatted as Ext4 . But no detected usb storage on VOXL2.
The connection is exactly the same as the example.

voxl2:/$ lsusb -t

/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/1p, 480M

Version of VOXL2

@Alex-Kushleyev

Thank you for the information. Now I understood about the parameters and numbers.

Regarding IMX214 (https://www.modalai.com/products/msu-m0025-2) + M0036 cable (https://www.modalai.com/products/m0036),
it is working without M0036 cable. (hires and tracking cameras are connected only with M0084 (https://www.modalai.com/collections/accessories/products/msu-m0084)

You are correct. The camera IS detected using voxl-camera-server -l but does not stream any images!!
I can see the detected cameras with voxl-camera-server -l,

DEBUG:   Cam idx: 0, Cam slot: 2, Slave Address: 0x00E2, Sensor Id: 0x7750
DEBUG:   Cam idx: 1, Cam slot: 3, Slave Address: 0x0020, Sensor Id: 0x0214
DEBUG:   Note: This list comes from the HAL module and may not be indicative
DEBUG:   	of configurations that have full pipelines

DEBUG:   Number of cameras: 2

Cam idx: 0 is tracking, and Cam idx: 1 is IMX214
But I cannot see the output of hires camera with M0036 cable.
