2.1.2.4. Assertion of PERST / warm reset during the Functional Level Reset results in PCIe* Link Failure

Description

In the R-Tile Intel® FPGA IP for PCIe* , you must avoid the PERST assertion during a functional level reset or before a functional level reset is completed since this could impact the link training process. This is also applicable when using the independent PERST feature to issue a warm reset (Independent GPIO PERST and Independent PERST pins). In case this occurs, a cold reset is required to properly complete the link training process.

Impacted Modes

  • PCIe* IP modes Endpoint

Workaround

None.
