APM 2.6 stops communicating with OSD when motors armed #68

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1.Turn on system (both OSD red lights on and green blinks. minimosd-extra start 
up screen appears and then the OSD appears and updates continually as it should)
2.Arm the APM. Motors spin and OSD freezes. Green light out
3.

What is the expected output? What do you see instead?
The OD data on the screen freezes and sometimes disappears. 

What version of the product are you using? On what operating system?
Using Minimosd 2.2 on Arducopter 3.1.3 (most recent I believe)

Please provide any additional information below.
Also I have the screen select set up on ch8 (mixer switch on TX) and this does 
not work.

I've followed this up more and the voltage out of the APM is just under 4.9 so 
I did some rewiring and fed the OSD board directly from the main BEC which puts 
out 5.3V. The OSD still shuts down on arming the motors and the power supply 
voltage is rock solid at 5.3 so I have no idea why this is happening. Is there 
a parameter that would affect this?

I forgot to mention that I added a ferrite core and capacitor to the power line 
supplying the APM and OSD board. I don't think noise is an issue... plus 
nothing else seems to be overly effected by noise.

I'm reading more and this seems to be an ongoing issue. Does one of the more 
recent pre-release  versions fix this? Any help would be REALLY appreciated. 
Thank you!

The most recent pre-releases (r726, r727) seem to fix the issue. Be sure to 
download the font too. You'll find this thread interesting.
