Hello @tom ,

Just following up on this.
Is there any potential way to revive the board?

Hello,

We are developing a quadcopter using VOXL ESC Mini 4-in-1 [M0129] with VOXL2 board.
We are using GEPRC SPEEDX2 1303.5 3800KV/5500KV Motor with a 2S battery.

We are facing issues with the motors running with the ESC.
One of the motors is not spinning even after throttling up. The pilot has to manually spin the propellers for it to start spinning. The ESC firmware is set by the VOXL automatically when voxl-configure-sku is run. Using a 4S battery helps, but we are limited to using a 2S battery.

voxl2:/$ voxl-inspect-sku

family code:   MRB-D0014 (starling-2)
compute board: 4 (voxl2)
hw version:    1
cam config:    27
modem config:  18 (Doodle RM-2450, 2.4GHz)
tx config:     6 (tbs_crossfire)
extras config: 8 (Lepton)
SKU:           MRB-D0014-4-V1-C27-T6-M18-X8

I wanted to understand if your team have worked with these motors.
In either case, would you be able to assist with understanding the motor behavior and debugging the same.

Regards,
Ashwin

Hello @Alex-Kushleyev,

Thank you for the confirmation.
It has helped us decide upon the architecture for the current and an upcoming project.
The suggested M0141 add-on is really helpful suggestion as well.

Regards,
Ashwin

@Alex-Kushleyev

I found a post on the forum stating that there is a library, namely libqrb5165_io, that can be used to access the port in the AP if I am not using PX4 (https://forum.modalai.com/topic/2916/j19-uart-port-mapping?_=1741378878682).

Is this still valid?
This is just an alternate in case we are not able to figure out any other means to read all the camera sensors into the DSP.

Regards,
Ashwin

Hello @Alex-Kushleyev ,

No, the TOFs were supposed to be read into the main DSP to process the data to understand the drone surroundings.
I was not aware that the I2C is only accessible from PX4.

Is there a potential alternate port that can be used for the same?
How about using the SPI port (J10)?

Regards,
Ashwin

@tom The output is exactly the same irrespective of whether the SW2 is ON or OFF.

Hello @Alex-Kushleyev,

We are actually planning to use the C27 configuration in the exact manner mentioned by you.

Also, you are correct that the TOF V2 is more capable than any I2C TOF we are finding in the market. But, as mentioned earlier, it is not possible to connect 4 TOF V2, so we are using the I2C TOFs with an I2C multiplexer to achieve the bare minimum objective.

The I2C multiplexer will be connected to the I2C3 port on the VOXL2 board (J19).

Ashwin

@tom I apologize for the delayed response.
I did refer to this document and am using the correct QDLimage.
I am using M0054-1 as the chip on the board says QRB5165M

@Alex-Kushleyev Our final solution will have 4 AR0144 (M0166) along with 4 ToF. The objective is to be able to view all sides of the craft along with distance sensing in all directions.
However, based on your responses, we are working on changing the architecture and instead use an I2C multiplexer with 4 I2C ToF sensors. As per my understanding, that should be integrable with 4 AR0144 cameras.

Thanks for the information. It would be really helpful in our decision making towards our project planning.

Hello everyone,

I am working on developing an indoor navigation solution using 4 Time-of-Flight sensors to provide 360-degree obstacle detection and mapping. The sensor board provided by ModalAI can only support one ToF sensor as per my understanding. I would like to understand if there is any way that I can integrate 4 ToF sensors and get their respective data into VOXL2 for post-processing.

Kindly feel free to reach out if there are any clarifications required on the requirement.
Looking forward to hearing back soon.

Hello everyone,

I am currently working with the VOXL2 Board. Following the instructions in the documentation (https://docs.modalai.com/voxl-developer-bootcamp/), I successfully started up the hardware and set up ADB. While setting up WiFi, I executed the command adb shell voxl-wifi, entered station mode, and provided the SSID and password for the WiFi connection. As instructed, I rebooted the hardware to complete the setup.

Since then, I have been unable to detect the hardware on ADB. Although the three LEDs on the board turn green, no device is detected on ADB. Assuming the firmware might be corrupted, I followed the unbricking guide (https://docs.modalai.com/voxl2-unbricking/). Despite following all the steps, the device is still not detected on ADB. Running the lsusb command shows the device being detected as a Generic Modem Driver (QDL mode).

I have also reattempted the unbricking steps, but they fail when trying to flash CDT.

I am seeking assistance to resolve this issue and resume working with the board. Please let me know if any additional information is required.

Looking forward to a quick resolution.

Regards,
Ashwin
