hi,we modified and complied the examples/xenomai/ example program. and run it in x86 and ARM(beagleboard black) board to drive a servo. the linux system can drive a servo, but get crushed in 1-2 hours  on x86 platform. however,  the cross-complied program crushed at starting it on ARM platform. 


we complied the realtime program and can run without problem. however, it cruched when we add the igh ethercat APIs.


our environment:
a) x86 intel 3GHz CPU+linux 3.14+xenomai2.6.4+igh 1.52
b) beagleboard black with 1Ghz TI A8 CPU+ linux 3.8 +xenomai 2.6.3+ igh 1.52


we are fllowing the instruction of both igh and xenomai to complied the paths. and now have no idea of solving the problem.


please help, we have working on this problem for 2 weeks.


thank,

I suggest you direct your question to igh then.

where is the code that you are using to drive the servo?

I am driving a Grove servo [1] using Xenomai3 and the following driver [2] to
generate the PWM with one of the available GPIOs - maybe you want to give it a
go if you are also using a gpio pin?
