[etherlab-users] Default Trap Handler: vector 14: Suspend RT task

[Kotlarski, Jens]

Hallo,

We had the problem explained in the following:

> >>> We are facing a problem concerning Rtai. Always when we load a kernel
> >>> object and start the etherlab_buddy we get the following error (it
> >>> occurs right after starting the buddy, insmod the kernel object works
> >>> fine): "Default Trap Handler: vector 14: Suspend RT task". Our system
> >>> only works if we load very very simple kernel objects, i.e models
> >>> consisting of a few Simulink blocks only.
> >>>
> >>> Maybe one of you had a similar problem and has some advice?!?
> >>>
> >>> By the way: we are using the Ethercat master 1.4 with Etherlab 1.2 on
> >>> an Ubuntu 8.04 system with Rtai 3.6.

We tried to update our system without success (we still had the TrapHandler problem). Finally, we figured out that we have to increase the RTAI Stack Size (Simulink -> Configuration Parameters). The default size was 2000. It works fine with higher values. Maybe this could help those of you having similar problems...


Regards,

Jens
