Hi Luciano,
 
Can you send mksu.substitutions and whatever .template or .db files it loads?
 
What do you get at the IOC prompt for
 
asynReport 10
dbpr  KLYS:IN20:3130:WF_TRIG_DELAY_WRITE 10
 
Mark

Hi,

I'm writing a simple asyn driver which I started out from the HMS example. When starting the ioc I get these messages:

        lpiccoli@cdlx22 iocMksu]$ ./st.cmd
        #! ../../bin/linux-x86/example
        dbLoadDatabase("../../dbd/example.dbd")
        example_registerRecordDeviceDriver(pdbbase)
        drvMksu_init()
        drvAsynIPPortConfigure("MksuServer", "194.168.0.21:56789 UDP", 0, 0, 1)
        initMksu("Mksu", "MksuServer")
        dbLoadTemplate("mksu.substitutions")
        iocInit()

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 type set to 0 (CONSTANT).

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

Thank you,
Luciano
