FPGA Programming from CFI Flash Memory

On either board power-up or by pressing the program load push button (S2), the

MAX V CPLD System Controller’s parallel flash loader configures the FPGA from the

flash memory. The system controller uses the Altera Parallel Flash Loader (PFL)

megafunction which 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 FPGA’s dedicated

configuration pins during configuration.

After a board power-up or reset event, the MAX V CPLD (U73) automatically

configures the FPGAs in FPP mode with the pre-installed factory .pof file. There are

three pages reserved for the FPGA configuration data—factory FPGA1 (page 0),

factory FPGA2 (page 1), and user design FPGA1 (page 2).

1 You must set the FPGA1_MSEL[4:0] or FPGA2_MSEL[4:0] DIP switch to FPP x8 mode

to configure FPGA1 or FPGA2 via FPP.

f For more information about the FPP configuration mode, refer to the Configuration,

Design Security, and Remote System Upgrades in Stratix V Devices chapter in the Stratix V

Handbook.

Three green configuration status LEDs,

PGM_LED[2:0]

(D1, D2, D3) indicates the status

of the FPP configuration. Table 2–7 lists the configuration status LEDs settings.
