Hi,

According to the pin connection guide, the unused PERST pin for the same GTS bank must be left floating.

Your PIN_CF132 and PIN_BU109 are on bank 5A and 5B, respectively. You may check the remaining PERST pins on these two banks.


Regards,

Rong

    Hello Rong,

    On the Arrow Eagle board :

    The PIN_CF132 (PCIE_PIN_PERST_N in GTS PCIe IP) is connected to the PERST# pin of the PCIe edge.

    The PIN_BU109 (PCIE_PIN_PERST_N_I in GTS PCIe IP) is left floating.

    I do not understand clearly what you mean by "You may check the remaining PERST pins on these two banks."

    Please see attached the schematic of the Bank 5A and 5B :

    Please let me know what I have to check exactly.

    Thanks.
    Serge
