154 int r = rt_task_create(&thread, thread_name.c_str(), 128*1024, prio,
T_FPU|T_JOINABLE);
Is there any trace on the serial console?
Hasn't been, but I now after I enabled Xenomai debugging and watchdog, at least there's
some indication what's going wrong. The "last words" of the application are
...
Xenomai: registered exported object (mutexes)
Xenomai: registered exported object (mutexes)
Xenomai: watchdog triggered -- signaling runaway thread 'pfda'
Backtrace: 0xbcdcc6, 0, 0, 0
And in gdb it shows up as a SIGXCPU:
Program received signal SIGXCPU, CPU time limit exceeded.
