Hi Luciano,
I am not spotting what your problem is, but it is probably something simple with the way you are building the application.
Here is a suggestion. asyn comes with an example application that demonstrates asynPortDriver, called testAsynPortDriverApp. That test application has ao and ai records that connect to an asyn port driver, and that driver is built with the asynPortDriver C++ base class. It is a simple digitial oscilloscope simulator. There is an test IOC directory, iocBoot/iocTestAsynPortDriver.
Does that test application work for you? If so, then there is nothing wrong with EPICS base or asyn, and the problem is with your application. You can then use testAsynPortDriverApp as an example of how to build your application. The only difference is that you also need to create a drvAsynIPPort server in addition to your device-specific server.
Mark

Now that you have fixed that record please send the output of
dbpr "record" 10
for all 4 records.
Also send the complete output when you start the IOC.
It does not make sense that dbpr is reporting DPVT=nil if you see the error message, since the error message is printed after DPVT is allocated.

Subject: RE: Asyn: "devAsynInt32::initCommon Link must be INST_IO"
Thanks Mark and Eric.
I made the suggested changes to the template file:
record(ao, "KLYS:$(AREA):$(LOCATION):WF_TRIG_DELAY_WRITE") {
field(DESC, "Waveform trigger delay (write)")
field(DTYP, "asynInt32")
field(OUT, "@asyn($(PORT) $(CHANNEL) $(TIMEOUT))WF_TRIG_DELAY_WRITE")
}
record(ao, "KLYS:$(AREA):$(LOCATION):MOD_TRIG_DELAY_WRITE") {
field(DESC, "Remote modulator trigger delay (write)")
field(DTYP, "asynInt32")
field(OUT, "@asyn($(PORT) $(CHANNEL) $(TIMEOUT))MOD_TRIG_DELAY_WRITE")
}
record(ai, "KLYS:$(AREA):$(LOCATION):WF_TRIG_DELAY_READ") {
field(DESC, "Waveguide trigger delay (read)")
field(DTYP, "asynInt32")
field(INP, "@asyn($(PORT) $(CHANNEL) $(TIMEOUT))WF_TRIG_DELAY_READ")
field(SCAN, "$(SCAN)")
}
record(ai, "KLYS:$(AREA):$(LOCATION):MOD_TRIG_DELAY_READ") {
field(DESC, "Remote modulator trigger delay (read)")
field(DTYP, "asynInt32")
field(INP, "@asyn($(PORT) $(CHANNEL) $(TIMEOUT))MOD_TRIG_DELAY_READ")
field(SCAN, "$(SCAN)")
}
However, in the previous mksu.template file only the KLYS:$(AREA):$(LOCATION):MOD_TRIG_DELAY_WRITE record had the DTYP/OUT in the wrong order and the error message appeared for all four records.
This is the Makefile section that defines the example.dbd:
DBD += example.dbd
example_DBD += base.dbd
example_DBD += asyn.dbd
example_DBD += drvAsynIPPort.dbd
example_DBD += mksu.dbd
Following the initialization it seems I have an issue when hitting line 181 in the devAsynInt32.c:181. The routine initCommon() is failing on pasinEpicsUtils->parseLink(), which is defined in asynEpicsUtils.c:67. In it the plink->type is 0 (CONSTANT) where I think the correct value would be INST_IO.
The asyn version is 4-14 by the way.
Thanks,
Luciano

Subject: RE: Asyn: "devAsynInt32::initCommon Link must be INST_IO"
Hi Luciano,
I am not sure what is wrong.
You said previously:
> Using gdb I see that they have the link type set to 0 (CONSTANT).
That is not what "dbpr" is showing for your record. It shows
OUT:INST_IO @asyn(Mksu 0 1)WF_TRIG_DELAY_WRITE
That looks correct, as does DTYP.
DTYP: asynInt32
Here are the fields that don't look correct in your record:
DPVT: (nil)
SEVR: <nil>
ASP: (nil)
DPVT is initialized in the initCommon function in
asyn/devEpics/devAsynInt32.c. It allocates that memory before it parses
the link, and parsing the link is where it prints the error message in
your original message. So I don't see how it prints that error message
and still has DPVT=(nil). And I don't understand why it is printing
that error message when dbpr shows the OUT link has the correct syntax.
I suspect a problem with your example.dbd file. How did you create that
file? Does it include all of the asyn dbd stuff?
Here is the output for an ao record with asyn device support for one of
my IOCs. Note that none of the files are are (nil) in your record are
(nil) in mine.

What do you get at the IOC prompt for

It looks like something is not getting set correctly, the link type of
those records should be INST_IO. Using gdb I see that they have the link

Am I missing something in the st.cmd file? Suggestions are welcome :)
