Well done mate. I have been following this issue on this forum since it started. To tell you the truth I have never read anything about attempting to restart the quad so many times. You may be onto a winner there. Keep up the great work.
We have been doing something similar, once for two hours without a result like that. Would be interesting to see what's happening under the hood. Its like there is an intermittent fault in one of the components.
Yeah, I wonder if it's just the battery. But I'm not really inclined to spend any money to find out, especially now that I can actually get it to work. I could probably figure how how to use a USB to serial device (in recent experience, I got XP running on an old Intel Mac, so I could use a USB-OBDII interact with my Toyotas using Techstream), but I don't have one.
yes, the right side is the stm which boots correctly , on the left is the dm368 which fails to boot.
Greetings. I was bayed 2 GoPro Karma drones. First cant pair with controller...i was trying to put different firmware but I cant successfully paired with drone. Then I bayed another controller but again no success in pairing. Problem is definitely in drone. Then I buyed anotehr Karma drone who was paired with their controller. I backup their firmware (2.50.1) then upload on first controller....but no success.
What if is problem in drone....in BT/Wifi board beneth motherboard? This is only my guessing.

The issue is with the drones bootloader, changing the firmware on the controller will not fix this.
It happens to me too, every 20 -30 time it straiten the gimble, but after 1 min power button gets red blinking and then power off if power on again gimble again not working
that sounds more like the OS is crashing or something is overheating. Same as above you need to connect a USB to UAT on J2 and see whats going on.
Im happy to loo kat these issues for people if you send your drone to me, you have to pay shipping to Australia and back to where you are.
We have made some break throughs, if you have a revision C mainboard we can fix this easily. We will release a video on the process at some point but need more revision C boards. You can determine this by removing the six hex screws that hold the cover on (two under the battery and one under each arm). There is a white label in the bottom right hand corner of the main board which shows what version it is. If you pay for shipping to get your drone to and from Australia we will fix it for you for free. We have fixed this for several revision C boards already. If you would like more information, we can be reached at [email protected].
