Failed to configure Altera PCIE reference design on Stratix IV development board

[Altera_Forum]

I am at the stage of testing the PCIE functions of Altera's Stratix IV GX Development Board. 

The reference design I am using is AN456 downloaded from Altera's website. As required, the Stratix IV GX board is plugged into the computer with x8 PCIE slot at 32-bit Windows XP. Error message (CONF_DONE pin failed to go high in Device 1) pops up whenever the configuration progress reaches 98% or 99% in Quartus programmer window.  Thanks for any advices!  Best regards, Xin

Xin, 

 I believe that the Stratix IV .sof files delivered with the reference design were compiled for an ES device. If your Stratix IV board has a production device, you will need to recompile the code and recreate the SOF for a non-ES target device.

Hi BrettFavre, 

I recompiled the design on the non-ES device and it finally worked. Many thanks for your help!  Best, Xin
