Two right-angle, 12-pin (2 x 6 female) Peripheral Module (PMOD) headers (J8, J9) are
interfaced to the FPGA, with each header providing 3.3 V power, ground and eight I/O's.
These headers may be used as general-purpose I/Os or to interface with the PMODs in
order to enable additional user customizations. J8 and J9 are placed in close proximity (0'9"
- centers) on the PCB in order to support dual PMODs.
The STEVAL-IME008V1 evaluation board supports the serial peripheral interface (SPI
Flash) method for configuring the FPGA. The default configuration mode (determined by
pullup/pulldown resistors R17, R18, R21, and R22) is "Master Serial / SPI" mode, which
allows the FPGA to be configured by the SPI Flash device. Spartan-6 devices have a
dedicated four-wire JTAG port (always available to the FPGA regardless of the mode pin
settings), allowing the Boundary-scan configuration method.
Configuring the FPGA via Boundary-scan requires a JTAG download cable to be attached to
the 14-pin 2 mm spaced keyed header J11 (to be mounted) with a ribbon cable. Resistors
RN1, R41 to R44 and diode D22 must also be mounted.
Jumper J13 is used to prevent FPGA programming from the configuration source. It must be
open (default) to enable FPGA programming. The DONE LED (D23) on the board lights
when the FPGA has successfully been configured.
