high on this net/pin selects BPI Flash device. See the Configuration Control
register at BAR0 + 0x300100 bit-0 for control of this signal.
Configuration Flash Design Considerations
After FPGA configuration, the FPGA design can disable the configuration
flash or access the configuration flash to read/write code or data.
When the FPGA design does not use the configuration flash, the FPGA
design should drive the FPGA BPI_Flash pin high in order to disable the
configuration Platform flash and put this flash into a quiescent, low-power
state. Otherwise, the Platform Flash, can continue to drive its array data
onto the data bus causing unnecessary switching noise and power
consumption.
To drive the FPGA BPI_Flash pin high set the Configuration Control register
at BAR0 + 0x300100 bit-0 to logic high.
JTAG Port
The JTAG port can be used to program the Virtex 6 FPGA and access the
device for hardware and software debug. The default
The JTAG port also allows a host computer to download bitstreams to the
FPGA using the Xilinx iMPACT software tool. In addition, the JTAG port
allows debug tools such as the ChipScope™ Pro Analyzer tool or a software
debugger to access the FPGA.
Through the connection made by the temporary design in the FPGA, iMPACT
can indirectly program the BPI flash or the Platform Flash from the JTAG
port.
