PCIe Root Port functionality in Arria 10

[SZack]

In the Arria 10/Cyclone 10 GX Avalon MM Interface for PCIe User Guide (June 2021) Table 2 and Table 11 seem to have contradictory statements about Root Port support.   Table 2 says Root Port is supported for both the ST and MM interfaces unless DMA is enabled.  In Table 11, at the top of page 26 it says

"You can enable the Root Port in the current release.  Root Port mode only supports the Avalon-MM interface type, and it only supports basic simulation and compilation. However, the Root Port mode is not fully verified."

So is Root Port mode fully supported or not?

Hi,

Root Port mode is supported in Avalon-ST interface type but example design generation for root port mode is not supported in Avalon-ST interface type.

Thanks

Hi,

The reply only refers to Avalon-ST interface.   Is the PCIe root port mode supported in Avalon-MM interface for Arria 10?

Thank you,
