So in this file i have to use some macros <br /> which tells How to connect or disconnect interrupts to your Hardware. <br /> <br /> on my board side the routing of interrupt from externel card to board is like this......<br /> <br /> <br /> <br /> <br /> ----------------- PCI --------------- PCI-e --------------- <br /> externel card/PMC ----------&gt; 8114 chip -------&gt; 8641D Core/CPU<br /> <br /> ----------------- INTA/B/C/D --------------- tx/rx ----------------<br /> interrupts will be lines will be<br /> generated by PMC pass to core <br /> <br /> <br /> so i am not able to get which interrupt controller in Core will Handle the Interrupt ....if possible i studied the reference manual for core also there is one pic interrupt controller and 1 pci Express interface controller also. but i didt get which controller will handle interrupts coming from my PMC......<br /> <br /> 2. also i want to ensure tht the interrupt coming from my externel card will be hardware interrupt or any software interrupt....if its software then which software interrupt<br /> <br /> <br /> PLZ help me...<br /> thanks in advance<br /> <br /> mark.S<br /> Mon, 04 Jan 2010 03:25:40 -0700
