Running EPICS on RTEMS/MVME3100

["Marks, Nicholas via Tech-talk" <tech-talk@aps.anl.gov>]

Hello,

Has anyone succeeded recently in getting an IOC to run on RTEMS on the MVME3100?  I've been trying but haven't had much luck. I have built RTEMS 6.1 using the RTEMS source builder with the MVME3100 BSP and I have successfully run several of the provided test applications (https://github.com/RTEMS/rtems/tree/main/testsuites/samples). I also built EPICS base 7.0.9 for RTEMS-mvme3100, however any EPICS applications I create do not work. I believe the failure is during BSP initialization before the IOC code even enters the picture since if I remove everything from the IOC's main function except a single printf, the same crash is present, and no print. I've pasted the VME console output below this message.

Note that the console hangs for several minutes after this line "ds1375_probe (open): No such file or directory" before printing the 

""%s" is not a valid command pathname." message, which comes from either 

base/modules/libcom/RTEMS/score/rtems_init.c 

or
base/modules/libcom/RTEMS/posix/rtems_init.c 

When running the RTEMS test programs that work, the "ds1375_probe..." line is not present.
Any suggestions would be appreciated. Thank you.
