FPGA Programming over External USB-Blaster
The JTAG programming header provides another method for configuring the FPGA
(U19) 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 (J5). Install a shunt onto the JTAG chain header (J9) pins 1 and 2 to remove
the MAX II CPLD device from the JTAG chain so that the FPGA is the only device on
the JTAG chain.
