Edit: solved
Solder joint miraculously went bad in between dimu and AQ board. Resoldered and working now.
So I got my auto quad flying beautifully after a lot of work and troubleshooting.
Then I was doing a bit of last min tuning before a job and it refused to boot up when I plugged it in. I tried repowering repeatedly with the same result. When I was about to give up I tried repowwering one more time and I booted fine. I flew all day that day with no more issues.
Now I'm on the first flight of a job and it refuses to boot up. All I get is one red light. I'm using an AQ 6 revision 2 board with dimu.
What should I do?
Any help would be appreciated.
