The MAX II device on the board contains a parallel flash loader (PFL) megafunction.
When the board powers up, the PFL reads one of two designs from flash memory and
configures the FPGA. The rotary switch (SW2) controls which design to load. When
the switch is in the 0 position, the PFL loads the design from the factory portion of
flash memory. When the switch is in the 1 position, the PFL loads the design from the
user portion of flash memory.
1 The development kit includes the MAX II configuration design in the <install
dir>\kits\stratixIVGX_4sgx230_av\examples\max2 directory.
When configuration is complete, the CONF DONE LED (D5) illuminates, signaling
that the Stratix IV GX device configured successfully.
