Fpga Configuration - 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 five UltraScale+™ FPGA configuration modes:
• Quad SPI flash memory (2 Gb)
• JTAG using:
USB JTAG configuration port (U8 FT4232HL + USB J2 micro-AB)
○
Xilinx ® Platform Cable USB II, 2 mm, keyed flat cable header (J4)
○
Each configuration interface corresponds to one or more configuration modes and bus widths, as
listed in the following table. The mode switches M2, M1, and M0 are on SW1 positions 2, 3, and
4, respectively. The FPGA default mode setting M[2:0] = 001 selects the master SPI
configuration mode.
