I am using a DIO-96 for stimulus and response during testing of a PC104 board. An fpga on the board is preprogrammed to execute part of some of the tests. The fpga uses some of the DIO signals for input and others for output.
The tests all run okay, EXCEPT, some of them consistently fail if I exit LabVIEW, restart LabVIEW, then restart the test vi (which configures the DIO96 ports as inputs or outputs once, then uses them as mentioned above). If the same test is run a second time, everything is okay. If I just exit the test vi and restart the test vi, everything is okay, but not if I restart LabVIEW. Based on this sketchy information, does anyone have an idea why starting LabVIEW might cause such a failure? Thanks for your thoughts. (I am using LabVIEW 6.0.2 and Win XP. The board under test is left on.) Jon
