08:22 AM pere: anyone here interested in trying to build mesa firmware using free software?
08:26 AM Tom_L: Efinix or Xilinx?
08:27 AM Tom_L: i've done a couple Xilinx but not Efinix yet
08:27 AM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/emc/xilinx/xilinx14_install_index.php
08:28 AM Tom_L: it's been a while....
08:29 AM Tom_L: i think hte Efinix may be a bit more complicated
08:31 AM Tom_L: that link info is also in the wiki
08:43 AM pere: how can I tell which one is in 7i80HD-25?
08:47 AM pere: Tom_L: is Xilinx Design Suite 14.5 free software?
08:55 AM pcw--home: Its free to use but not open source (14.7 is the last that supports Spartan 6)
09:02 AM pcw--home: The "Webpack" variant of ISE is free to use, the Efinix toolset is also free to use but not open source (though it probably should be since it uses VPR from the University of Toronto for placement and routing and that is open source (MIT license))
09:44 AM pere: right. I am talking about free software like yosys, not proprietary closed source without payment requirements.
03:38 PM rmu: pere: https://github.com/Peter-van-Tol/LiteX-CNC
03:41 PM rmu: hmm. forget that link.
03:44 PM pere: rmu: too late. Thanks. :)
03:45 PM andypugh: I seem to be having a problem with the mb2hal test, and that problem seems to be due to the checkresult script running before the component load is complete.
03:49 PM andypugh: I am wondering if something has broken the -W of loadusr -W ?
03:51 PM andypugh: rmu: were you looking at parallel LinuxCNC instances? (I was looking through the pull requests earlier)
04:01 PM rmu: andypugh: yes 1-2 years ago i think
04:02 PM andypugh: There was a brief exchange in March
04:02 PM andypugh: https://github.com/LinuxCNC/linuxcnc/pull/2722
04:04 PM andypugh: It’s come up recently on the forum. https://forum.linuxcnc.org/38-general-linuxcnc-questions/56630-running-two-linuxcnc-instances-in-parallel?start=0#331744
04:06 PM andypugh: I am wondering if they shoould share the same shared memory, but prefix all their pins with an instance ID. (only for second, third etc)
04:06 PM andypugh: (This may not be difficult, as the pin creation code only exists in one place)
04:37 PM rmu: as long as the size of shared mem is large enough, it should be possible
04:38 PM rmu: no idea about cleanup if one of the instances quits or is restarted though
04:40 PM rmu: hmm. can't reach the forum.
04:40 PM rmu: 503 service unavailable
04:49 PM Tom_L: it's been sluggish all day
04:50 PM rmu: working again
