Dear all, I'm using a
asynPortDriver (4.33) with EPICS base (3.16). The way I create my
asynPortDriver is: EWBAsynPortDrvr(const char *portName,int max_nprm) and I have one example PV defined as: record(ao, "$(user):BoardIDSet"){ field(DTYP ,"asynInt32") field(OUT ,"@asyn($(PORT),$(ADDR),$(TIMEOUT))board_ID") field(DESC ,"Board Identification") field(VAL , "3") field(LOPR, "0") field(HOPR, "5") field(PINI ,"YES") } record(ai, "$(user):BoardIDRdbk") { field(DTYP ,"asynInt32") field(INP ,"@asyn($(PORT),$(ADDR),$(TIMEOUT))board_ID") field(SCAN ,"I/O Intr") field(DESC ,"Board Identification") } If I set BoardIDSet to a certain value (for example: 3)
BoardIDRdbk does not see the change and it doesnt get updated. But
if I try to write again BoardIDSet following error ocurrs:
Error in
`/home/sevensols/bpm/bpm_epics/bin/linux-x86_64/AsynBPM7S': double
free or corruption (fasttop): 0x00000000023e1b70 ***
Can somebody tell me whay the I/O Scan is not working? And also why this error ocurrs Thank you very much in advance! --
