Can't Arm after Activating Failsafe

[seikurou]

Have a HK 328p on stock TGY 9x. <-- Does failsafe even work with that?
After uncommenting the failsafe option in config.h, motors will not arm.
Usually a solid blue LED lights up when armed, but this time it flashes on and off once.
the threshold setting doesn't appear to be a problem as nothing ever goes below 985
I just need a working failsafe that's as simple as shutting off the motors.

Thanks everyone

That seems unusual.
Connect the USB and run the MWconf.exe gui. Check that all the stick values are correct.
The FS threshold should check only the first four RX channels.

If you comment out the FailSafe and re-load the code can you Arm?

Forgot to mention that this was all done in the gui...
Yes, everything works normal when reloading the code. I do have to reset PID and aux assignments
After uncommenting and turning on failsafe gui flips out and doesn't respond

My main problem is getting it to actually arm with failsafe active.
Maybe it's not compatible with my board somehow?

The most common problem for Failsafe and ARM is throttle is to low in min position.
There is a threshold value for the first 4 channels. ( 980µs default )
If ex throttle is below threshold value Failsafe is activated and you can see that ANGLE mode always is active in Gui.

Trim up throttle to ~1010µs then the Failsafe should release.

A activated Failsafe Enables Angle mode and prevents Arming.

The function is the same for all Flightcontrollers

Same problem here (MW 2.4). I have uncommented FAILSAFE, and then It only arms sometimes. In other attemps I only get flasking the leds, but not arm. I have checked the code and I think it enters in go_arm() function (because the flashing leds and beeps -I have buzzer-), but I dont know why I have FailsafeCnt >2 so it doesnt arm.

If I comment FAILSAFE in config.h it arms everytime .

As PatrikE said in the post above yours:
Check the Stick End Point values. If they exceed the FS threshold values then it goes into FS mode and will not allow arming.

Thx waltr, but my end point values are fine. If I comment the FAILSAFE option I can ARM and DISARM w/o problems.

If ex throttle is below threshold value Failsafe is activated and you can see that ANGLE mode always is active in Gui.

This goes for the first 4 channels.
Check the ANGLE box in Gui.
If it's always active you have triggered Failsafe somehow.

[ardufriki]

Check the ANGLE box in Gui.
If it's always active you have triggered Failsafe somehow.

ANGLE is always active for me (three boxes checked ON), I think the problem is the part of the code concerning to FAILSAFE (cause I uncommemt it and it works fine). I use FAILSAFE from my RX, so it should not be a big issue, I guess.

[ardufriki]

welll...I think I have solved the issue.

Lowered the FAILSAFE_DETECT_TRESHOLD from 985 to 885 and it works fine !!

Now I have both failsafes; the RX failsafe set to RTH and the Multiwii failsafe (in case RX fails).
