Sometime ago, NASA Langley Research Center began a project to port the IOC
Core from vxWorks to LynxOS. We have accomplished that goal.
The port is of EPICS version 3.12.2 since that was the version current when
we started the effort. The target software platform is LynxOS 2.5.0 and the
target hardware platform is the KineticSystems (KSCorp) V151, a VXI Slot-0
controller based on the Force PowerCore 603ev (PowerPC). Also ported were
the device drivers from KSCorp for "Reality" version 1.4*. These drivers
support the following KSCorp VXI modules:
- V387 Discrete Input/Output Module
- V266 Digital-to-Analog Conversion Module
- V208 Analog-to-Digital Conversion Module
- V243 Analog Multiplexer Module
All EPICS 3.12.2 functionality is included except I/O interrupt scanning
and Access Security. Our applications do not currently use these features
so we did not port them.
Although the code has been tested in the software lab, we have not been
able, due to resource constraints, to test the port against either our
dSpace-based tunnel simulator or an actual facility. We believe, however,
that the port has equivalent functionality to the original vxWorks version.
We are unable to pursue this effort any farther due to resource
constraints. We will make the port available to the Collaboration. Anyone
interested in picking up where we left off?
