@modaltb Yes, we used r14.1a_1.1.2-M0054-14.1a-FLAT-V3.zip as well.

We will make a try with removing all the hardware connection.

@Eric-Katzfey We've tried replacing power cable with a spare. Tried fastboot and qdl again, but it doesn't work.

@Eric-Katzfey Thanks. We will try as soon as possible. Are there any more possible solutions that might solve this problem?

We need VOXL 2 to work urgently. Can we get any remote assist? Thanks.

@tom Yes, entering into fastboot mode is possible. We tried re-flashing with voxl2_platform_1.3.1-0.8/system-image/flash-system-image.sh. But after flashing, it doesn't go after but only waiting for ADB.

[INFO] Waiting for ADB

@tom Yes, it reached the point. The result is written on the previous replies.

@tom Yes, we did.

@tom We've ran factory reset with qdl and this is the output.

After performing qdl, if we run lsusb without turning off the power, it gives us this.

If we cycle power and run lsusb, it is still shown below. It is not recognized as 05c6:901d.

@Adrian-Hidalgo We disconnected ToF and reconnected with the original Hi-Res camera. Also, we've checked the camera connections, but had no issue about it. However, we've disconnected GPS module, as we don't need it. Can this be the reason?

@tom This is the full output of lsusb.

Hi, we have a problem with using Sentinel through ADB.

We bought Sentinel and we were able to connect with ADB. Also, other packages such as voxl-mapper worked fine. We needed more accurate map in indoor, so we disassembled VOXL Flight Deck and replaced Hi-Res camera with PMD ToF Sensor from VOXL CAM. However, from that point, connecting through ADB doesn’t work.

To resolve this problem we tried reflashing by fastboot.

1. Fastboot mode by pressing SW1 for 30 secs.
2. $ fastboot device
3. $ sudo ./install.sh -f

Flashing finished but doesn’t do anything but only printing “Waiting for ADB”. adb devices couldn’t detect any device.

What we have checked:

1. Reflashing using Fastboot
2. Power

• Using Gens ACE 3S, 60C, 5000mAh and Sentinel’s power module

3. Cable

• Using USB A to C, wasn’t causing problem before.
• Connecting cable after 10 secs. powering.

4. Environment

• Tested through variety of devices(PC, laptop, windows, mac, ubuntu)

5. lsusb

• Detects usb to “Qualcomm, Inc~”

6. adb

• Version 1.0.39
• Tried adb kill-server

How can we connect through ADB? Thanks.

Additionaly, the Follow Path button doesn't shows up on the GUI of voxl-portal.

Hi,
I am using Sentinel Drone with voxl-portal and voxl-mapper.
We've changed voxl-mapper.conf to work with stereo camera.
However, plan to a point is not working. When we give a point, it generates trajectory, but Sentinel doesn't move at all.
We've changed offboard to trajectory. Is there any solution to it?
Thanks.

@Arjun-Jain Thanks. Is it possible in real-time processing?

Hi,

I'm working on integrating other service based on voxblox map on voxl-mapper. Is there any ways to export map made from voxl-mapper like ROS advertising?

Thanks.
