Bus Error on Raspberry Pi 2 #33

Open zazics opened 9 years ago

zazics commented 9 years ago

Hello,

I've built "naoqi_driver" on a Raspberry Pi 2 using "catkin_make_isolated". Except this warning "extended initializer lists only available with std=c++0x or -std=gnu++0x", everything built correctly. But, when I run: "rosrun naoqi_driver naoqi_driver_node --qi-url=x.x.x.x wlan0" I get a "Bus error" message and process stops.

I have no problem using libqi in another C++ program to control Nao from my Raspberry Pi.

please verify that you start the bridge correctly and that you are on the latest version. You can find the instructions on how to start your node here: http://ros-naoqi.github.io/naoqi_driver/start.html#start-the-naoqi-driver-module

Yes, I downloaded the latest version a few days ago. I followed that documentation. If I undertand it well, I only have to start "roscore" and "rosrun naoqi_driver ....". Am I right ? Maybe my problem is due to ARM architecture of Raspberry ?

You get a memory corruption right ? (please write your error message again). We've never tested that bridge or libqi with raspberry pi so that could indeed be a problem. @Karsten1987 , maybe you can show him how to disable certain modules so that we narrow down the corruption.

my error message is just "Bus error". Nothing more, nothing less. This error occurs immediately after the bridge has started. "Libqi" seems to work well on a Raspberry Pi 2. I can send order (move, speech, joint) to Nao, read memory and react to events. I found this thread: https://www.raspberrypi.org/forums/viewtopic.php?f=33&t=102400 It talks about some hard float point / memory alignment problem. I will try to investigate more as soon as possible.
