thanks to all of you, that was the problem, I had only defined 6 channels, but there arrived 8 at the tiny.
After adding 2 unused channels it worked. The Telemetry_mode_fbw works as well.

Best Regards

Hi Tim,

you updated your airframe file to the subsystems?
You can still activate the ppm message just like before and like it says on the wiki ( ) by adding
  <define name="TELEMETRY_MODE_FBW" value="1"/>
to the firmware section in your airframe file.

What changed and I guess is your problem is that now the ppm signal is better checked for validity and the number of channels has to match _exactly_ to be a valid signal.

Cheers, Felix

I had a working setup with an older version of paparazzi (svn checkout 2009-07) after migration to a newer version (git 2010-11-28) the radio doesn't work anymore. The aircraft is in auto2 all the time. I checked with an oscilloscope: The pulses arrive at the tiny. So it must be an software problem.

I tried to activate the ppm messages but the information in the wiki about this is outdated (old airframe config file).

Can someone tell me how they should be activated in the current version, or what might be the reason for the not working radio ?

I wish everybody a good start into next year
