Stratix V PCIe CvP not working

Hi,

Thanks for the additional information and printscreen, Apologize for missing some important information.

I do a deep check for Stratix V CvP gen2 procedure.

Indeed Stratix V does support CvP at Gen2, due to a published errata, customers must order specific product variants with fixed silicon.

Please see errata, PCIe Gen2 Link Training Error When Using Hard Reset Controller. As CvP must use the hard reset controller, then this errata applies.

The good news is that a fix part is available, your customer is reported as using:

5SGSED8N2F45I2L

But they must order parts with the full part number:

5SGSED8N2F45I2LCV

The *CV indicates fixed PCIe Gen2 silicon Hard Reset Controller.

Without fixed silicon, only Gen1 is supported in Stratix V.

Hope this clarified,

Regards,
