Using VEEK-MT2
This section describes the detailed information of the components, connectors, and pin assignments of
the VEEK-MT2.
3.1 Configuring the Cyclone IV E FPGA
The Video and Embedded Evaluation Kit (VEEK-MT2) contains a serial configuration device that
stores configuration data for the Cyclone IV E FPGA. This configuration data is automatically loaded
from the configuration device into the FPGA every time while power is applied to the board. Using the
Quartus II software, it is possible to reconfigure the FPGA at any time, and it is also possible to change
the non-volatile data that is stored in the serial configuration device. Both types of programming
methods are described below.
1. JTAG programming: In this method of programming, named after the IEEE standards Joint Test
Action Group, the configuration bit stream is downloaded directly into the Cyclone IV E FPGA. The
FPGA will retain this configuration as long as power is applied to the board; the configuration
information will be lost when the power is turned off.
2. AS programming: In this method, called Active Serial programming, the configuration bit stream is
downloaded into the Altera EPCS64 serial configuration device. It provides non-volatile storage of
the bit stream, so that the information is retained even when the power supply to the VEEK-MT2 is
turned off. When the board‟s power is turned on, the configuration data in the EPCS64 device is
automatically loaded into the Cyclone IV E FPGA.

JTAG Chain on VEEK-MT2
To use the JTAG interface for configuring FPGA device, the JTAG chain on the VEEK-MT2 must form
a closed loop that allows Quartus II programmer to detect the FPGA device. Figure 3-1 illustrates the
JTAG chain on the VEEK-MT2. Shorting pin1 and pin2 on JP3 can disable the JTAG signals on the
HSMC connector that will form a close JTAG loopback on DE2-115 (See Figure 3-2 ). Thus, only the
on-board FPGA device (Cyclone IV E) will be detected by Quartus II programmer. By default, a jumper
is placed on pin1 and pin2 of JP3. To prevent any changes to the bus controller (Max II EPM240)
described in later sections, users should not adjust the jumper on JP3.
