Description Due to a mistake on the Agilex™ 7 FPGA F-Series Development Kit (2x F-Tile) (AGF023), the PCIe* Independent GPIO PERST# is shown going to two Pin locations: GXF_2ND_PERSTn signal on Pin CN11 on Sheet 22 should be DNU (Do Not Use). GXF_1V2_2ND_PERSTn signal on Pin B46 on Sheet 16 is a valid GPIO on Bank 3A, and this should be used. Resolution When testing Independent GPIO PERST# in Bifurcated 2x8 Mode on the Agilex™ 7 FPGA F-Series Development Kit (2x F-Tile) (AGF023), either test in Single PERST# Mode when both x8 Cores are connected to the same host, or use Pin B46, which is a valid GPIO in Bank 3A.
