Hello Yiming
That problem looks strange. In streamApp.dbd you should find a line like

device(stringin,INST_IO,devstringinStream,"stream")

This line defines that stringin records with DTYP "stream" have INST_IO
link type, not CONSTANT. At the moment I have no idea how you can have a
CONSTANT link there.
Please send the complete boot output of our ioc.

Hello

I have a problem in streamDevice2.

I use the streamDevice to control a VME monitor. As the example in
streamApp,I have three files: vme.cmd,

vme.db,vme.proto.These are parts of them:

-------------------------------------------------------------------

vme.cmd

!./streamApp
dbLoadDatabase "O.Common/streamApp.dbd"
streamApp_registerRecordDeviceDriver
#where can protocols be located?
epicsEnvSet "STREAM_PROTOCOL_PATH", ".:protocols:../protocols/"
#setup the busses
#example serial port setup
drvAsynSerialPortConfigure "COM1", "/dev/ttyS0"
asynOctetSetInputEos "COM1",0,"\r\n"
asynOctetSetOutputEos "COM1",0,"\r\n"
asynSetOption ("COM1", 0, "baud", "9600")
asynSetOption ("COM1", 0, "bits", "8")
asynSetOption ("COM1", 0, "parity", "none")
asynSetOption ("COM1", 0, "stop", "1")
asynSetOption ("COM1", 0, "clocal", "Y")
asynSetOption ("COM1", 0, "crtscts", "N")
dbLoadRecords "vme.db","PREFIX=VME"
#dbLoadRecords "scalcout.db","PREFIX=DZ"
iocInit
#enable debug output
var streamDebug 1
-------------------------------------------------
      vme.db
record(stringin, "$(PREFIX):T2") {
  field(DTYP, "stream")
  field(INP, "@vme1.proto spyT2 COM1")
  field (SCAN, "I/O Intr")
}
record(stringin, "$(PREFIX):T3") {
  field(DTYP, "stream")
  field(INP, "@vme1.proto spyT3 COM1")
  field (SCAN, "I/O Intr")
}
.......
-----------------------------------------------------
     vme.proto
Terminator =" ";
ReplyTimeout = 10000; # 10 sec is very long, for keyboard input
ReadTimeout = 2500;   # also long for keyboard input
spyT2{
   in "T2:%2c";
}
spyT3 {

in "T3:%2c";

}

.......

------------------------------------------------------------

Last month,it works well, I can get the value from the VME monitor
with it.

Recently,I install CSS_EPICS_2.3.0-boy, I want to desire a manager
display for it.

But the problem happened.This is the error :

-------------------------------------------------------------

#dbLoadRecords "scalcout.db","PREFIX=DZ"

iocInit

It works bad ,I don't know why this happen.I run
"example.cmd","test.cmd",they have the

same problem.Interesting,only "stringin" record performs error,others
run well.

Please help me,looking forward to your reply.
