Reference Manual

Figure 2–4 shows the PFL configuration.

f For more information on the following topics, refer to the respective documents:

■ Board Update Portal, PFL design, and flash memory map storage, refer to the

Cyclone V E FPGA Development Kit User Guide.

■ PFL megafunction, refer to Parallel Flash Loader Megafunction User Guide.

FPGA Programming over External USB-Blaster

The JTAG chain header provides another method for configuring the FPGA using an

external USB-Blaster device with the Quartus II Programmer running on a PC. To

prevent contention between the JTAG masters, the embedded USB-Blaster is

automatically disabled when you connect an external USB-Blaster to the JTAG chain

through the JTAG chain header.
