VXI 1394 viMove error

"1394 Slot 0 viMoveOut16 error"

"I just updated NI-VISA from 2.5.2 to 3.2. When I now run my application I get a bus error during a viMoveOut16 function call. Using VIC I was able to determine that viMoveOut16 will return a bus error code when the transfer count is > 2000. Is there a setting to increase the transfer count?"

Hello,

If you could provide the error number and message it will help troubleshoot. What seems to be happening is that the number in length + the offset is greater than the space in memory then it gives an error. To correct this, change the length size to be smaller or allocate more memory. There is a function called ViMapAddress that is used to set the amount of memory.
If this doesn't fix the problem, please provide with the error message.
As a reference here is the link to the VISA Programmer User Manual
NI-VISA Programmer Reference Manual

Hope this helps

The error I was getting was:

BFFF0038 Bus error occurred during transfer.
(VI_ERROR_BERR)
It is not an offset error, there is 128K of memory.

viMoveOut16 was able to execute within the entire 128K as long as the transfer count was less than 2000.

I updated NI-VXI from 3.2 to 3.3.1 and the problem has disappeared.
