Re: [Emc-developers] PCIe EPP parport issues
Sam, I lowered the base thread to 25uS and the encoder error: rtapi_app: caught signal 8 - dumping core , is gone! -Bari Brand new setup using stepconf. if I spin the spindle encoder quickly by hand I get: rtapi_app: caught signal 8 - dumping core Even if the machine is still in e-stop. Simple config using stepconf LINUXCNC - 2.9.0~pre0 and 5.10 preempt_rt All default settings other than manual edit of LPT base address and changed setp encoder.0.position-scale 4000.00 Default is like 100 vs 4000 Any ideas what causes this error? https://forum.linuxcnc.org/media/kunena/attachments/1324/simple.ini https://forum.linuxcnc.org/media/kunena/attachments/1324/simple.hal The only mention of a similar error: forum.linuxcnc.org/24-hal-components/358...hercat-lcec?start=10 https://forum.linuxcnc.org/49-basic-configuration/46796-rtapi-app-caught-signal-8-dumping-core All the files are here. ^^ ___ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers
Re: [Emc-developers] PCIe EPP parport issues
one interesting thing... If you crash out of 2.9 - the installed 2.8 won't start until you re-launch and exit 2.9.. (no - linuxcnc is already running - do you want to exit?) I will get the error that comes up when you try to launch 2.8... sam On Tue, Sep 6, 2022 at 4:43 PM andy pugh wrote: > On Tue, 6 Sept 2022 at 22:34, Bari wrote: > > > So it looks like an RTAI bug with 2.8 at least about the encoders > > signals to spindle RPM GUI in Axis. > > > > Will go back and trace why preempt_rt has issues with LPT encoders in > > LCNC 2.9. > > If there is a difference between the realtime versions then I would be > looking in the rtapi code for different implementations of rtapi_inb > https://linuxcnc.org/docs/stable/html/man/man3/rtapi_inb.3rtapi.html > > -- > atp > "A motorcycle is a bicycle with a pandemonium attachment and is > designed for the especial use of mechanical geniuses, daredevils and > lunatics." > — George Fitch, Atlanta Constitution Newspaper, 1912 > > > ___ > Emc-developers mailing list > Emc-developers@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-developers > ___ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers

If there is a difference between the realtime versions then I would be looking in the rtapi code for different implementations of rtapi_inb https://linuxcnc.org/docs/stable/html/man/man3/rtapi_inb.3rtapi.html -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 ___ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers

And no signal 8 core dump with LCNC 2.8 and RTAI OK tested LCNC 2.8 with preempt_rt and the encoder signals make it to the GUI using a preempt_rt kernel vs RTAI! NO signal 8 core dump \0/ So it looks like an RTAI bug with 2.8 at least about the encoders signals to spindle RPM GUI in Axis. Will go back and trace why preempt_rt has issues with LPT encoders in LCNC 2.9. Another odd thing is that when also testing the CH382 LPT PCIe card the encoders signals are making it from encoder to BOB through the CH382 and I can see them in halscope BUT the steps generated do not make it out of the CH382 to the BOB. But CH382 debug is another project. And today I see similar issues with ALL my other LPT controllers with 2.9 and 5.x preempt_rt kernels ___ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers

[Emc-developers] PCIe EPP parport issues
I have been selling Syba SD-PEX10005 PCIe parallel port cards for several years, they seem to work well with most computers and LinuxCNC and my line of motion interfaces. Now, I have 2 Dell Optiplex 7010 computers that they do NOT work on. It seems that both my diagnostic program and the hal_ppmc driver don't talk to it correctly. These cards use the MOSCHIP MCS9900 or MCS9901 chip. I have one remaining Siig card that uses the Oxford Semi chip and it works. I thought I had this EPP weirdness pretty much solved, but now I'm up the creek without a paddle again. Does anybody know anything about these PCIe-EPP issues? Thanks in advance for any help!
