Interrupts on Adlink PCO-7224 with PLX 9052?

Question

Hi!I'm currently trying to use the onboard timer on the Adlink PCI7224 [1] to generate fast interrupts under WinNT/RTX. But I couldn't manage it to generate an interrupt.The interrupthandler is attached and reacts on software triggered interrupts. But also the timer i8254 is running, no "local" interrupt at the PLX 9052 is generated, and so #INTA line does not change. I also tried to generate an interrupt with an I/O line (pin P1C0), but this does not work either.In the describtion of the PCI 9052RDK-LITE [2] a linux drives with sourcecode is mentioned. Is there any way to get these sources without buying the complete RDK? Adlink does not respond to my request for driver sources :-(Kind regardsThorsten Ostermann[1]   Kunst kommt aber von 'können',nicht von 'kennst du schon den neuesten trick?'

Adlink support is rubbish and the quality of their drivers isn't much better.

I have only worked with a PLX9080 on a different Adlink board. To generate interrupts from an I/O line and timer I needed to:-

Enable those interrupts in the Adlink interrupt control/status reg (INT_CSR).

Enable the local to PCI interrupt in the PLX chip.

Enable the PCI interrupt on the PLX chip.

PLX do an SDK for $99 which has full source code for a generic windows driver for their PCI chips.
