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 devel

opment 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.

f For mor

e information about the PFL megafunction, refer to AN 386: Using the Parallel

Flash Loader with the Quartus II Software.
