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)Link Copied

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
