[Paparazzi-devel] Parrot AR 2.0 Problem Telemetry Data

k Hello,

I have tried the last days to autopilot my Parrot AR 2.0 but there is one problem arising between me and my goal: the telemetry data is not being transferred from the drone to the gcs application (It lasts forever without any change).
I use ubuntu 16.04.
The parrot software: 2.4.8.0.
Paparazzi release: v5.12_stable.
Airframe: ardrone2.xml
Telemetry: default_rotorcraft.xml

(Some of these settings differ from the tutorial
since the tutorial is with an older release of paparazzi)
It compiles and uploads without any problem, but the GCS does not initialize to the expected state. I have tried the solution proposed by https://lists.gnu.org/archive/html/paparazzi-devel/2016-08/msg00018.html but the result is the same. The file ap.elf again returns "var/aircrafts/ardrone2/ap/ap.elf: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), statically linked, for GNU/Linux 3.2.0 [..]".
I still get the error:
# ./ap.elf
FATAL: kernel too old
Segmentation fault

It would be an immense help if you have any ideas about this problem's solution.
Cheers!

Hello,

After reading some posts around the web I was able to solve the described
problem in my first post by following the instructions from
https://wiki.paparazziuav.org/wiki/AR_Drone_2 .

Thank you!
Dimitar
