Configuration, Status, and Setup Elements

This section describes the board's configuration, status, and setup elements.

Configuration

This section describes the FPGA, flash memory, and MAX

II CPLD EPM2210 System

Controller device configuration methods supported by the Cyclone IV GX Transceiver
starter board. The Cyclone IV GX Transceiver starter board supports the following
configuration methods:

Embedded USB-Blaster is the default method for configuring the FPGA at any
time using the Quartus II Programmer in JTAG mode with the supplied USB cable.

Flash memory download is used for storing FPGA images which the MAX

II

CPLD EPM2210 System Controller uses to configure the Cyclone IV GX device
either on board power-up or after the PGM configure push-button switch (S8) is
pressed.

External USB-Blaster for configuring the FPGA using an external USB-Blaster.

Serial configuration (EPCS) device (U15) is used to store configuration data for
FPGA device that supports active serial (AS) configuration and reloads the data to
the FPGA upon power-up or reconfiguration.

FPGA Configuration over Embedded USB-Blaster

The USB-Blaster is implemented using a USB Type-B connector (J5), a FTDI USB 2.0
PHY device (U5), and an Altera MAX II CPLD (U4). This allows the configuration of
the FPGA using a USB cable directly connected between the USB port on the board
(J5) and a USB port of a PC running the Quartus II software. The JTAG chain is
normally mastered by the embedded USB-Blaster found in the MAX

II CPLD

EPM240M100.

The embedded USB-Blaster is automatically disabled when an external USB-Blaster is
connected to the JTAG chain.

Figure 2–4

illustrates the JTAG chain.
