Hi Mrinal,
Thanks to Mark Rivers and APS-BCDA Group, I could successfully build a new VME Crate system with EPICS 7.0.4 and vxWorks 6.9.4 with the following hardware configuration:1) MVME 31002) MAXv 80003) OMS StepPak SPD-32M Motor Drivers
While booting the MVME board I am getting the following error while loading the motorUtils.db and couldnot figure out the reason.
epics> dbLoadRecords("$(MOTOR)/db/motorUtils.db","P=CRL15Sraight:")filename="../dbStatic/dbLexRoutines.c" line number=271S_errno_ENOENT dbRead opening file /home/epics/synApps/support/motor-R7-2-2/db/motorUtils.dbdbLoadRecords: failed to load '/home/epics/synApps/support/motor-R7-2-2/db/motorUtils.db'
That is a not-terribly friendly message that I think just means "file not found". You are loading an nfsCommands file but oes your VxWorks system have the /home/epics/synApps path mounted? Try typing
ls "/home/epics/synApps/support/motor-R7-2-2/db/motorUtils.db"
at the shell, my guess is that it won't be able to find it and that you will need to adjust what you're mounting, or maybe have the application install the file into its own db directory and load it from there.
HTH,
- Andrew
