2.1.2.16. Bifurcated ports using Independent PERST pins might fail to link up after configuration is complete
Description
When using Enable Independent PERST pins to implement bifurcated x8x8 ports in R-Tile Avalon Streaming Intel FPGA IP for PCI Express in Endpoint mode, both ports might fail to link up if one of the ports is not supplied with a reference clock (refclk0/1) and its corresponding pin_perst0_n/pin_perst1_n is not tied to a weak pull-down during configuration. After configuration is complete and the reference clock(s) (refclk0/1) become available, toggling the pin_perst_n or the corresponding pin_perst0_n/pin_perst1_n does not recover the links and you must reconfigure the FPGA.
Impacted Modes
- PCIe* IP in endpoint mode
Workaround
None.
