Re: Problem with drvAsynIPPortConfigure

[Mark Rivers via Tech-talk <tech-talk at aps.anl.gov>]

Hi Dariush,

Both Mark Engbretson  and Ralph Lange have explained what the problem is, but perhaps you did not understand.

You need to change your st.cmd so that these lines to near the top.  They must come before any of the asyn commands.

## Register all support components
dbLoadDatabase "dbd/mdrive_1IOC.dbd"
mdrive_1IOC_registerRecordDeviceDriver pdbbase

So your st.cmd should look like this:

#!../../bin/linux-x86_64/mdrive_1IOC
< envPaths
cd "/home/xlabsrv2/epics/IOCs/mdrive_1IOC"
## Register all support components
dbLoadDatabase "dbd/mdrive_1IOC.dbd"
mdrive_1IOC_registerRecordDeviceDriver pdbbase

epicsEnvSet ("STREAM_PROTOCOL_PATH", "/home/xlabsrv2/epics/IOCs/mdrive_1IOC/db")
epicsEnvSet ("PORT_mdrive_x", "ip_x")
#X Axis
drvAsynIPPortConfigure(ip_x, "100.100.0.23:503")
asynOctetSetInputEos(ip_x,0,"\n\r")
asynOctetSetOutputEos(ip_x,0,"\n\r")
asynSetTraceMask(ip_x,-1,0x9);
asynSetTraceIOMask(ip_x,-1,0x2)
## Load record instances
#dbLoadRecords("db/mdrive_1IOC.db","user=xlabsrv2")
dbLoadTemplate("db/mdrive_1IOC.val")
cd "/home/xlabsrv2/epics/IOCs/mdrive_1IOC/iocBoot/iocmdrive_1IOC"
iocInit

Hi Community,
I didn't write all the codes that are automatically generates by makeAppBase.pl application. By the way, I'll report below all the infos:

# mdrive_1IOC.dbd will be created and installed
DBD += mdrive_1IOC.dbd

# mdrive_1IOC.dbd will be made up from these files:

mdrive_1IOC_DBD += stream-base.dbd

# Add all the support libraries needed by this IOC
#mdrive_1IOC_LIBS += xxx
mdrive_1IOC_LIBS += stream
mdrive_1IOC_LIBS += asyn

# mdrive_1IOC_registerRecordDeviceDriver.cpp derives from mdrive_1IOC.dbd

# Build the main IOC entry point on workstation OSs.
mdrive_1IOC_SRCS_DEFAULT += mdrive_1IOCMain.cpp
mdrive_1IOC_SRCS_vxWorks += -nil-

# Add support from base/src/vxWorks if needed
#mdrive_1IOC_OBJS_vxWorks += $(EPICS_BASE_BIN)/vxComLibrary

# Finally link to the EPICS Base libraries

I think you have the order of things in the startup file wrong.

The block

## Register all support components

dbLoadDatabase "dbd/mdrive_1IOC.dbd"

mdrive_1IOC_registerRecordDeviceDriver pdbbase

loads the dbd file and registers all Record, Device and Driver Support modules with EPICS. This includes the registration of iocShell commands.

Before this block is run, the iocShell does not know the asyn-related commands.

Cheers,
