FPGA Programming from Flash Memory
Flash memory programming is possible through a variety of methods. The default
method is to use the factory design—Golden Hardware Reference Design. This design
contains an embedded webserver, which serves the Board Update Portal web
application. The web page allows you to link to SoC-related web pages and to control
some user I/O and LCD on the development board.
On either power-up or by pressing the program configuration push button,
PGM_CONFIG
(S12), the MAX V CPLD 5M2210 System Controller's PFL configures the
FPGA from the flash memory.

This feature is disabled by default. To enable this feature, slide the FACTORY_LOAD DIP
switch (SW2.3) to the ON position.
The PFL megafunction reads 16-bit data from the flash memory and converts it to fast
passive parallel (FPP) format. This 16-bit data is then written to the dedicated
configuration pins in the FPGA during configuration.
Pressing the PGM_CONFIG push button (S12) loads the FPGA with a hardware page
based on which PGM_LED[2:0] (D39, D40, D41) illuminates.
Table 2–6 lists the design that loads when you press the PGM_CONFIG push button.
