The DE1-SoC Development Kit presents a robust hardware design platform built around the Altera
System-on-Chip (SoC) FPGA, which combines the latest dual-core Cortex-A9 embedded cores
with industry-leading programmable logic for ultimate design flexibility. Users can now leverage
the power of tremendous re-configurability paired with a high-performance, low-power processor
system. Altera’s SoC integrates an ARM-based hard processor system (HPS) consisting of processor,
peripherals and memory interfaces tied seamlessly with the FPGA fabric using a high-bandwidth
interconnect backbone. The DE1-SoC development board is equipped with high-speed DDR3
memory, video and audio capabilities, Ethernet networking, and much more that promise many
exciting applications.
The DE1-SoC Development Kit contains all the tools needed to use the board in conjunction with a
computer that runs the Microsoft Windows XP or later.

When the DE1-SoC board is powered on, the FPGA can be configured from EPCS or HPS. The
MSEL[4:0] pins are used to select the configuration scheme. It is implemented as a 6-pin DIP
switch SW10 on the DE1-SoC board, as shown in Figure 3-1.
Figure 3-1 DIP switch (SW10) setting of Active Serial (AS) mode at the back of DE1-SoC board
Table 3-1 shows the relation between MSEL[4:0] and DIP switch (SW10).

Figure 3-1 shows MSEL[4:0] setting of AS mode, which is also the default setting on DE1-SoC.
When the board is powered on, the FPGA is configured from EPCS, which is pre-programmed with
the default code. If developers wish to reconfigure FPGA from an application software running on
Linux, the MSEL[4:0] needs to be set to “01010”before the programming process begins. If
developers using the "Linux Console with frame buffer" or "Linux LXDE Desktop" SD Card image,
the MSEL[4:0] needs to be set to “00000” before the board is powered on.

There are two types of programming method supported by DE1-SoC:
1. JTAG programming: It is named after the IEEE standards Joint Test Action Group.
The configuration bit stream is downloaded directly into the Cyclone V SoC FPGA. The FPGAwill
retain its current status as long as the power keeps applying to the board; the configuration
information will be lost when the power is off.
2. AS programming: The other programming method is Active Serial configuration.
The configuration bit stream is downloaded into the quad serial configuration device (EPCS128),
which provides non-volatile storage for the bit stream. The information is retained within EPCS128

even if the DE1-SoC board is turned off. When the board is powered on, the configuration data in
the EPCS128 device is automatically loaded into the Cyclone V SoC FPGA.
JTAG Chain on DE1-SoC Board
The FPGA device can be configured through JTAG interface on DE1-SoC board, but the JTAG
chain must form a closed loop, which allows Quartus II programmer to the detect FPGA device.
Figure 3-2 illustrates the JTAG chain on DE1-SoC board.

Configure the FPGA in JTAG Mode
There are two devices (FPGA and HPS) on the JTAG chain. The following shows how the FPGA is
programmed in JTAG mode step by step.

The DE1-SoC board uses a quad serial configuration device (EPCS128) to store configuration
data for the Cyclone V SoC FPGA. This configuration data is automatically loaded from the
quad serial configuration device chip into the FPGA when the board is powered up.
Users need to use Serial Flash Loader (SFL) to program the quad serial configuration device
via JTAG interface. The FPGA-based SFL is a soft intellectual property (IP) core within the
FPGA that bridge the JTAG and Flash interfaces. The SFL Megafunction is available in
Quartus II. Figure 3-9 shows the programming method when adopting SFL solution.
Please refer to Chapter 9: Steps of Programming the Quad Serial Configuration Device for the
basic programming instruction on the serial configuration device.
