Well, I recently had problems with analogy (2.6 release, 4.6 compiler), but my problems were with analog sync input. Had too much to do at that time to investigate further, so I recompiled my old 2.5.x xenomai with -fno-omit-frame-pointer just to get that machine shipped shipped away to the physics department to do some quantum dot experiments. > > Could you tell us which version of Xenomai and which driver > (ni_pcimio, ...) you are using? > > Regards, > > Alexis. >> >> Many thanks to both of you for your ideas ! >> >> Hadrien >> >> On Tue, Nov 22, 2011 at 1:33 PM, Anders Blomdell >> wrote: >>> >>> On 11/22/2011 01:06 PM, Alexis Berlemont wrote: >>>> >>>> Hi, >>>> >>>> On Mon, Nov 21, 2011 at 3:20 PM, Gilles Chanteperdrix >>>> wrote: >>>>> >>>>> On 11/21/2011 12:10 PM, Hadrien Caron wrote: >>>>>> >>>>>> Thanks very much Wolfang ! >>>>>> Cool script, I didn't know about it :) >>>>>> I'll try to correct my code with that information ! >>>>>> >>>>>> Thanks again, >>>>> >>>>> ENOSYS usually means that you have not enabled the relevant support in >>>>> kernel configuration. >>>>> >>>> >>>> Which driver are you using?
