Xilinx VCU128 User Manual

9. If using the ATX supply 8-pin (2x4) PCIe power connector, plug the connector into VCU128
board JP1. The PC can now be powered on.
FPGA Configuration
The VCU128 board supports two of the ve UltraScale+™ FPGA conguraon modes:
• Quad SPI ash memory (2 Gb)
•
JTAG using:
○ USB JTAG conguraon port (U8 FT4232HL + USB J2 micro-AB)
○ Xilinx
®
Plaorm Cable USB II, 2 mm, keyed at cable header (J4)
Each conguraon interface corresponds to one or more conguraon modes and bus widths, as
listed in the following table. The mode switches M2, M1, and M0 are on SW1 posions 2, 3, and
4, respecvely. The FPGA default mode seng M[2:0] = 001 selects the master SPI
conguraon mode.
