After I sent a question to tech-talk, we found the following fact:
1) NI-1014 DMA can access VME address in A24 mode.
2) To accesse Main memory on FORCE cpu40 via VME bus, address mode
should be A32 mode.
These facts means that the standard GPIB support routines in EPICS does not
work for this combination of boards. We happened to have memory board for VME
bus and allocated buffer space GPIB driver on this memory board. After that,
GPIB support routines are working.
