Custom component using SOPC builder (PCIe S2gx dev board) Please HELP

Hi,

I built two SOPC systems (Quartus 7.2 SP3) each of which has NIOS, PCIe, JTAG, PLL and PIO component. PIO is tied to 8 bit LED on the Stratix II GX development board

simplePCIE_Q72:

- All the components used are from SOPC component library.

- Works fine; LED changes state according to the 8-bit data passed through PCIe component.

simplePCIE_Q72_custom_PIO:

- PIO component is built using component editor, with the pio.v file generated in the first project. I think I have all the connections correct.

- This project doesnt work; the LEDs are always at 0x0 state.

I am sought of lost on this problem :confused: and not sure why it is not working. Any help would be greatly appreciated.

Thanks a lot.

PS: the projects are uploaded as attachments. (http://www.alteraforum.com/forum/newthread.php?do=newthread&f=31)

    Hi,

    I looked at the the First example of Nios II with PCIe and PIO.

    How are you transferring the data from PCIe component to Led PIOs...?

    I am more interested in Nios II Software code which can do this Data transaction..?

    Kindly reply asap
