PCIe not receiving interrupts

SP7 — Fri, 08 Jan 2010 16:16:11 GMT

Why don't I see any interrupts comming from my intel Z5xx series ATOM board for my PCIe device. If I plug in same exact PCIe device into desktop based chipset any pentium or so..and I also use exact same driver I do see interrupts comming..

do I have to do anything extra for this ATOm processor family to get my PCIe device working..I see there is a nwe block SCH in intel atom Z series could that be the cause..

Any help would be appreciated..Not sure if this is the right forum to post my query as well..

Hello, SP:

Welcome to the Intel® Embedded Community. Yes this is a good forum to ask your question about Intel embedded processors.

Can you tell us more about your configuration? Are you using a commercial board or is it your custom design? OS?

Thanks

Felix

Its a custom intel ATOM motherboard, OEM board with Z530 and 510 chipset..I can certainly share more detila in this regards if you tell me specifically what..

Can you also please let me know if my driver need to configure SCH...

Forgot to mention I am also running on a custom OS..This custom OS works on any other intel chipset family..
