Hey, my voxl is stuck in waiting for device after trying to unbrick it with the addon board. I tried basically everything and followed the instructions precisly and tried power cycling it etc. Some help on what to do would be appreciated :)

Are you able to communicate with other devices using ADB?

Have you tried 'adb kill-server' to make sure it's not a stale ADB session?

Are you supplying enough current for the board to boot? If you use ModalAI's Power Adapter you should be fine. If it's custom, sometimes not enough current is provided.

I'm just gonna leave this here if it affects others aswell:
I was stuck on the issue for a while but it was indeed an adb issue. Restarting it didn't fix the issue and I couldn't debug what the problem seems to be. Using another device (laptop) did work tho and I was able to unbrick it.
Thanks for the inputs Chad.

Wanted to update this by saying I experienced same issue, but I resolved this by disconnecting tracking camera that had been installed upside down. So, if anyone is reading this in the future....try disconnecting your cameras attached to the board
