Configuration Options
[Figure 2, callout 36]
The VCU128 board supports two of the seven UltraScale™ FPGA conguraon modes.
• Master SPI using the onboard 2 Gbit Quad SPI ash memory
• JTAG using:
○ USB JTAG conguraon port J2 (FTDI FT4232H bridge U8)
○ Xilinx
®
plaorm cable 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 4-pole DIP SW1
posions 2, 3, and 4, respecvely. The FPGA default mode seng M[2:0] = 001, selecng the
master SPI conguraon mode.
