WatchDog Reset Hard Fault on CUAV-X7+:
Hello everyone we are currently facing watchdog reset problem in CUAV-X7+ based on ardupilot 4.0.4
we included the board support for CUAV-X7+ to our firmware. But recently in a drone, between mid flight a watchdog reset occur, and we are unable to find the root cause of it, as per the logs we are getting its a hard fault. please look into these log file.

There are important fixes in ArcuCopter 4.0.7. Do you have a good reason to ignore them?
Please update to ArduCopter 4.2.1 and re-test.

with this firmware I have taken more than 150+ flights, this is first time I encounter the watchdog reset problem, I am just trying to find the valid reason of it. Please help me into this to understand the reason behind the watchdog or how to debug this problem, I will port to the latest ArduCopter soon.
I also encountered this problem,4.0.5
Strange… all people that seam to have this problem have outdated FW … what could be the problem? … is there a pattern here???
I have over 100 flights on a CUAV-X7 with ArduCopter 4.1.5

The takeoff started well and the plane restarted at 5 meters

@amilcarlucas So there is any specific way to generate watchdog due to HARDFAULT for debugging purpose .
@ItsSaket The very first link provided in this post is dead.
So far I have never seen the problem, so I do not know how to trigger it.
@rmackay9 have you ever seen this on ArduCopter 4.2.1?

I am experiencing this issue on a mroControlZeroF7 with FW 4.2.0. After reboot the following message is printed out:
WDG: T0 SL0 FL217 FT3 FA200220F0 FTP180 FLR20022FD8 FICSR4466691 MM0 MC0 IE0 IEC0 TN:Ardu
For some reasons this happens every time that I switch to Land mode
Does it still happen after you update to ArduCopter 4.3.5 ?

In the end was my bad, the real cause was an unchecked nullptr on some modifications of the code that I made.
No issues were encountered in both 4.3.5 and 4.2.0 then.

@ItsSaket If you update to AP4.34, you will be able to locate faults faster.
