What is the correct process to recover the voxl 2?

[m1baldwin]

The instructions on the documentation for re-flashing the system image on the voxl 2 doesn't quite match what the latest scripts from the voxl2 platform 0.9 image tar provide. The package provides an "install.sh" script as the entry point for re-flashing. The instructions mention there should be a "flash-full.sh" script.

Assuming the above is supposed to be the correct script, I did try putting my voxl 2 into fastboot state and running the install script. It was able to identify the partition and reset the board, but it hangs at the "Waiting for ADB" step. The voxl 2 is showing up in dmesg as a Qualcomm device, but adb doesn't show it as available, hence it hanging at the waiting for adb step.

Any ideas on what to try?

@m1baldwin You're right, the newer releases changed the name to install.sh

Can you post the output of lsusb on your host PC so we can see exactly what state the VOXL2 is booting into?

Output from lsusb when voxl2 has been placed in fastboot mode:

@m1baldwin I would double check that your SW2 switch is OFF. If it is, it seems as though your VOXL2 may be in a bricked state and can be recovered via. QDL: https://docs.modalai.com/voxl2-qdl/

[m1baldwin]

Yes, SW2 is in "off" state, so looks like voxl 2 is bricked. I'll try out the qdl instructions and come back with updates.

[m1baldwin]

@tom That qdl reset did the trick, thanks!
