9 years agoPcie link training failed (CycloneIVGX)
Hi all!
I have problem with link training between FPGA(CYIVGX) and DSP. DSP: Ltssm alredy located at state 0x00 and 0x01 (detect.quiet and detect.active). FPGA: Ltssm alredy located at state 0x03 (polling.compliance). I do not understand what is the reason of my problem. I'm used megafunction IP Compiler for PCIe (without QSYS) and ALTGX_RECONFIG. http://www.alteraforum.com/forum/attachment.php?attachmentid=12739&stc=1 http://www.alteraforum.com/forum/attachment.php?attachmentid=12740&stc=1 http://www.alteraforum.com/forum/attachment.php?attachmentid=12741&stc=12 Replies

Hi, Did You solve this problem?
I have a similar problem. I have TMS320C6655 and 5CGXFC7D6 connected on my board. In most power-on link training is correct. But sometimes LTSSM in FPGA hang in Polling.Compliance. Why Polling.Compliance arise? It seems to don`t arise in normal operation. Can I prevents the LTSSM from entering Compliance?
