We would love to see an embedded Linux on our MVME boards. We have a perfectly good root file system that we use on a handful of our boards and on quite a
number of other targets (Libera and PandA in particular), but our kernel is *extremely* old and the patch set is gigantic (Keith who I’ve CC’d will remember where we obtained it). We have not had the effort available to get a maintainable and up to
date kernel version (last I looked it seemed to me that the Tornado support was out of tree), and so we just use our VME Linux on a handful of very basic (limited read only) systems to free up enough vxWorks licences to keep us going elsewhere. I’m pretty
sure our long term plan is to abandon VME altogether … in the *long* term. Migrating back to vxWorks sounds like a horrid idea! From: [email protected]
[mailto:[email protected]] On Behalf Of Goetz Pfeiffer Hello, at the Helmholtz-Zentrum Berlin (https://www.helmholtz-berlin.de/) we use EPICS for our control system. We have a growing number of soft IOCs with Linux and VME bus based IOCs mostly running RTEMS and
Our CPU boards are MVME162 and MVME2100. We have replaced more than half of the old MVME162 boards with After migrating most VME CPUs to RTEMS 4.9 we have run into some problems:
A possibility would be to use vxWorks again. Our current vxWorks version is
very old and has to be updated. Problems here:
What are your experiences with this ? Do you still use VME bus systems ? Is there a future for RTEMS in EPICS control systems ? Are there alternatives to RTEMS and vxWorks ? Greetings, Goetz Pfeiffer
