FPGA Programming over External USB-Blaster

The JTAG programming header provides another method for configuring the FPGA

(U15) using an external USB-Blaster device with the Quartus II Programmer running

on a PC. The external USB-Blaster is connected to the board through the JTAG

connector (J8). Removing all shunt jumpers from the JTAG chain header (J11) removes

all devices from the JTAG chain so that the FPGA is the only device on the chain. To

add the MAX

II CPLD EPM2210 System Controller to the JTAG chain, place a shunt

on the JTAG chain header (J11) pin 1 and 2.

Table 2–9. Board-Specific LEDs (Part 1 of 2)

Board Reference LED Name Description

D3 Power Blue LED. Illuminates when 12-V power is active.

D7 JTAG_AT_SEL Green LED. Illuminated when the default JTAG chain is broken and the MAX II

EPM2210 System Controller has control of the FPGA JTAG pins.

D13 CONF DONE Green LED. Illuminates when the FPGA is successfully configured. Driven by the

MAX II CPLD EPM2210 System Controller.

D14 INIT DONE Green LED. Illuminates when the FPGA is successfully configured and is in user

mode. This setting must be selected in the Quartus II programmer.

D11 LOAD Green LED. Illuminates when the MAX II CPLD EPM2210 System Controller is

actively configuring the FPGA. Driven by the MAX II CPLD EPM2210 System

Controller.

D10 Error Red LED. Illuminates when the MAX II CPLD EPM2210 System Controller fails to

configure the FPGA. Driven by the MAX II CPLD EPM2210 System Controller.

D12 FACTORY Green LED. Illuminates when the factory image is loaded to the FPGA. Driven by

the MAX II CPLD EPM2210 System Controller.
