stratix II GX high performance ref. design test failed

[Altera_Forum]

Hi. 

 I'm trying to run the PCI E high performance reference design (an 456), on a Stratix II GX PCI Express developement board (EP2SGX90F1508C3). I programmed the board with de .sof file available in the PCIe_hiperf_s2gx_agx.zip file. The sop file is top_x4.sof in /PCIe_hiperf_s2gx_agx/sip_gen1_x4_stiigx/ directory. I installed the demo driver and software executable used for running the reference design on the board.   I pressed "Run Endpoint DMA" and then the program crashed.
