The ML550 Development Board provides a push-button program switch (SW12) for
initiating the configuration of the Virtex-5 FPGA. This switch is used to force a
reconfiguration of the FPGA from PROMs if they are present and enabled. The ML550
Development Board does not include PROMs.
The primary configuration device is the System ACE Controller (U13), which loads image
files from a CompactFlash card. The mode DIP switch (SW11) must be set to the proper
mode for configuration to occur via the System ACE interface (refer to
Modes” on page 45
push button simply clears the FPGA configuration on this board.
The ML550 development board provides a USB “B” connector for interface to a PC (using
a USB B-to-A cable.) The board uses a Silicon Labs 3.3V CP2102 USB-to-RS232 converter
device (U2) to drive the RD, TD, RTS, and CTS signals to the FPGA via a Maxim MAX3008
level translator (U20). The user must provide a UART core internal to the FPGA to enable
serial communication. A Silicon Labs CP2102 driver file is included on the ML550
development kit CD. This driver allows a PC USB port to be configured as a serial COM
port for the user to continue working with serial communication utilities like
HyperTerminal or Tera Term Pro.
