PCIe BFM

Has anybody tried the PCIe RP BFM in Version 15.1? I walked through the design example defined in the “Arria 10 Avalon-MM DMA Interface for PCIe Solutions” document. The BFM did communicate with BAR0 descriptor controller and performed the DMA read/write transfers. That worked great, but when I added add a few more tasks to the “altpcietb_bfm_driver_rp” driver module to exercise some BAR4 endpoint communication without DMA, The RP could only successfully perform reads and not write operations to the endpoint dual port memory. I pulled a ticket and they sent it to Asia? Not too hopeful but we will see......
