Hi Mark,
  Yes, it's there:

peter@peter-Latitude-E7240:~/zed/root/scint/dbd$ grep device\(ao *
scintscal.dbd:device(ao,CONSTANT,devAoSoft,"Soft Channel")
scintscal.dbd:device(ao,CONSTANT,devAoSoftRaw,"Raw Soft Channel")
scintscal.dbd:device(ao,CONSTANT,devAoSoftCallback,"Async Soft Channel")
scintscal.dbd:device(ao,VME_IO,devAoI2C,"I2C DAC")    <---------
scintscalRecord.dbd:device(ao,VME_IO,devAoI2C,"I2C DAC")

Pete.

Hi Pete,

I think that means your dbd file did not actually get incorporated into the dbd file that got loaded into your IOC.  Look at the application dbd file and see if you can find that device(ao...) line in it.

Forgive me, this is probably very dumb.

I have an IOC which uses a scaler record and a bunch of ao records. THe
scaler record dbd file has this line to register the ao device support:

device(ao,VME_IO,devAoI2C,"I2C DAC")

The support routine devAoI2C exists. I use VME_IO because Epics then
nicely parses out the config parameters. However when I run make, I get
this error:

/opt/epics/base/bin/linux-arm/dbToRecordtypeH  -I. -I.. -I../O.Common
-I../../../dbd -I/opt/epics/base/dbd ../scintscalRecord.dbd
scintscalRecord.h
Record type "ao" not found for device "I2C DAC"

The build stops there, before it compiles anything else. What am I missing?

Pete.
