Problems with NI-488 cPCI adapter under QNX.

[bearhug]

Hi Michael,

The problems that I am having with the NI 488 cPCI adapter are random, so
it is
very difficult to nail down where the problem lies. Sometimes the adapter
fails
the initialization sequence in the nitn_presence_check routine at various
points in the 4 tests that the driver performs. Other times, if the adapter

initialization passes, the driver will loop in the nitn_wrtPIO with the
message
"waiting, isr3=0x4c" or "waiting, isr3=0x00". I have added a loop count to
the
routine so that it exits after 100 loops, but it still affects the driver
performance. I have had a similar problem with the nitn_wrt1byte routine.

I have been told that the driver works under Windows and Linux, but it
doesn't
work under QNX, and I have no idea why not, as I don't have any chip-level
documentation on the adapter. I will appreciate any help that you can give.

Thanks, Hugh.

Hi bearhug,

This post was a little confusing. Was it started in another thread and moved over to a new one accidentally? Since it appears that you have had some previous correspondence, I looked into the type of issue you are experiencing and it looks like Michael, one of our Applications Engineers, has an in-work service request related to it. If that is your service request, I would encourage you to contact him directly by calling 1-866-275-6964 and entering the service request number there. Please let me know if there has been some miscommunication.

Best regards,

Matt J

Yes, I sent it to Michael, but I received an e-mail telling me to post it here.
