Overview
(DS180)
FPGA Configuration
The FPGA is configured in JTAG mode only using one of the following options:
•
USB JTAG configuration port (Digilent module)
•
System ACE SD controller
The FPGA is configured through the Digilent onboard USB-to-JTAG configuration logic
module (U8) where a host computer accesses the KC724 board JTAG chain through a
standard-A plug to micro-B plug USB cable. (callout
The FPGA is configured through the System ACE SD controller by setting the 4-bit
configuration address DIP switch (SW8) to select one of eight bitstreams stored on a Secure
Digital (SD) memory card (see
System ACE SD Configuration Address DIP Switches,
