@Jetson-Nano Given the crash and hardware issues I'd recommend sending this board in for an RMA

Eric Katzfey

I'm not sure I understand your issue. Can you connect via USB cable to adb into the drone? When you say PX4 is beta version, do you mean the VOXL SDK is a beta version? Can you provide the version numbers? What software did you write that enabled you to connect to the drone?

Eric Katzfey

Yes, unfortunately the answer is still the same. Our ESC is not yet supported by ArduPilot on ChibiOS platform so can only be used when running ArduPilot directly on VOXL2. Why do you need the separate FC hardware?

Hey @Eric-Katzfey ,
I have similar query. Not exactly the same, but I want to run ardupilot along with Voxl fpv 4 in 1 ESC.
Ardupilot on 3rd party FC.

The architecture that I would like to try out is :

Voxl 2 ---> 3 rd Party FC (with ardupilot)----> voxl FPV 4 in 1 ESC

Especially since flight core v2 has reached EOL. Is any new FC being release?

Please help me out here.

@ModalAI-Team Help me out here . I want to purchase some new components, but with out having a clear idea on the architecture I won't be able to do it.
Please guide me here.

@ModalAI-Team
If anyone could help me understand this behaviour and help me solve the boot issue, if there was any way, would mean a lot.

I have 2 VOXL 2 which are not booting. which gave successful result in unbricking but did not detect ADB earlier. That was until last day when while trying unbricking the same boards, I got a positive result in one of the boards.

If this issue can solved by anyway, please help me out.

Hey @Moderator ,

I had few more questions regarding the same.

Does the 3D map generated have the same quality has PMD TOF?
Can the 3D map be used for P-to-P navigation from voxl-Portal?
Can the TOF data be used for collision prevention?
Can multiple maps be used together?
Does Multiple TOF give collision prevention in multi direction?
If you could provide a image of map generated by the new TOF, it would be great and help us to make a decision for our architecture.

Thank you for your help and time, looking forward to your response.

I am able to download the log from the site along with all of the parameter settings. The accelerometer bias is clear in the log. Can you try to recalibrate the IMU with air flow on the unit to keep it from getting too hot? The yaw estimate error is not active during the log. However, to remove the interaction with VIO, try setting EKF2_EV_CTRL to 0 and see if that clears that occasional error. If it does then that helps narrow the issue to the VIO input versus the magnetometer / IMU input. Is the red light on the GPS unit or the RC receiver?

Re: voxl2 is not booting

@alex-kushleyev @vinny @eric-katzfey @modaltb

I was trying to unbrick the same voxl 2 again, which was successful and I was even able to flash the 1.4 SDK, and both showed successful. As I completed the reboot after flashing, the board went back to the boot mode, it is not able to pass the boot loop, the LED is constantly ON, ADB is unresponsive again.

Since the log data is huge, I am sharing the link to the log below. Please help me understand this behaviour.

Can you provide a px4 log to help diagnose the "High Accelerometer Bias" and "Yaw Estimate Error" issues? Normally a log file is only generated after the drone is armed but you can force a log to start by issuing the command px4-logger on at the command prompt on voxl2. Then after a few seconds issue px4-logger off to close the log file. The high temperatures may be causing the high accelerometer bias error. It's definitely best to have a fan blowing on the VOXL2 board if it will just be sitting on the desktop during development. For the yaw error perhaps you can take the drone outside and let it acquire a GPS lock and see if that resolves the error.
