epics dbpf problem

["Shi HaoLi" <shl@ihep.ac.cn>]

Hi, all

   Now I've built an EPICS (version 3.14.6) application using RTEMS(4.6.0), 
IOC is MVME5500. The peripheral hardware I/O module is PSC. The device 
support(devPSC.c) and the driver support(drvPSC.c) have been 
successfully compiled and can run on RTEMS. Database downloading related to 
PSC is OK, but when I execute dbpf, something wrong happens as 
follows: 

Cexp>dbpf ("R4IBT04:CISet", "3.0") 
0xffffffff (-1) 
filename="../dbTest.c" line number=365 
dbPutField error 
Cexp>dbgf ("R4IBT04:CISet")
DBR_DOUBLE          3
Cexp>dbl()
R4IBT04:CISet
R4IBT04:I
R4IBT04:ISet
......

any help is appreciated, thanks a lot!
