Introduction
This application note shows how to use a Synergy Software Package (SSP) Project in the Renesas Synergy™ e2 studio
to develop a simple NetX DNS application.
2.
Connect to the Board
This section describes how to connect and run the code.
1.
Refer to the Quick Start Guide for PE-HMI1, DK-S7G2, or SK-S7G2 for setting up the power connection and
the J-link debugger connection from your PC to the JTAG connector on the target board.
2.
Connect an Ethernet cable to the Target board.
3.
Connect the other end of the cable to the PC through a switch, crossover cable, or straight through to the PC
using an Auto MDI-X capable port.
NOTE: For the DK-S7G2 board, set DIPSW S5 “ENET1” switch to on, and use the Main Board Ethernet 1
port only.
3.
Import the Project into e2 studio
Refer to the "Synergy Project Import Guide" (r11an0023eu0100_synergy_ssp.pdf) for instructions on importing the
project into e2 studio and building the project. IMPORTANT NOTE: After importing the code into e2 studio and before
building the project, perform the following steps to setup the board for your network. Then continue with the Import
Guide to build and debug this project:
1.
The static IP address of the board is specified in SERVER_IP_ADDRESS in the file
/src/demo_nx_dns_http_application.h, using the macro: IP_ADDRESS(192,168,0,180). Modify this source file
to use the IP address for your computer. Make sure the IP address you select does not conflict with any other
computers or devices on your network. Note that the IP address numbers are comma separated in this macro.
2.
The IP address of the local DNS server is specified in DNS_SERVER_ADDRESS in the file
/src/demo_nx_dns_http_application.h. If you are not sure what your DNS server address is, use the command
ifconfig from a command prompt or ask your local network administrator. Modify this source file to use the
DNS IP address for your network.
3.
The IP address of the gateway is specified in IP_GATEWAY_ADDRESS in the file
/src/demo_nx_dns_http_application.h. If you are not sure what your gateway address is, use the command
ifconfig from a command prompt or ask your local network administrator. Modify this source file to use the
Gateway IP address for your computer.
4.
Save the changes (File > Save).
5.
Continue with the Import guide to Generate Code, build and debug the project.
NOTE: When asked to select the Debug configuration, select “NETX_DNS Debug”.

Application Features
This section describes the current features of the combined DNS client demo and Webserver application.
If you properly configured, built, and ran the application, you should see the orange light illuminated on the board near
Ethernet connector:
1.
In a command prompt window on your PC, enter the ‘ping’ command with the IP address that you specified in
the field SERVER_IP_ADDRESS of the file /src/demo_nx_dns_http_application.h:
2.
In a web browser enter the IP address that you used with the ping command in the previous step in the text
field where you normally place a URL, like www.google.com. You should see this:
3.
Enter a valid server name (for example, www.renesas.com) and click the Get IP address button. This will cause
the board to resolve the server address name to its internet IP address and display it in the browser.
4.
Click Terminate
to close the debugger.

General Precautions in the Handling of Microprocessing Unit and Microcontroller Unit Products
The following usage notes are applicable to all Microprocessing unit and Microcontroller unit products from Renesas.
For detailed usage notes on the products covered by this document, refer to the relevant sections of the document as
well as any technical updates that have been issued for the products.
1. Handling of Unused Pins
Handle unused pins in accordance with the directions given under Handling of Unused Pins in the
manual.
The input pins of CMOS products are generally in the high-impedance state. In operation with
an unused pin in the open-circuit state, extra electromagnetic noise is induced in the vicinity of
LSI, an associated shoot-through current flows internally, and malfunctions occur due to the
false recognition of the pin state as an input signal become possible. Unused pins should be
handled as described under Handling of Unused Pins in the manual.
2. Processing at Power-on
The state of the product is undefined at the moment when power is supplied.
The states of internal circuits in the LSI are indeterminate and the states of register settings and
pins are undefined at the moment when power is supplied.
In a finished product where the reset signal is applied to the external reset pin, the states of
pins are not guaranteed from the moment when power is supplied until the reset process is
completed.
In a similar way, the states of pins in a product that is reset by an on-chip power-on reset
function are not guaranteed from the moment when power is supplied until the power reaches
the level at which resetting has been specified.
3. Prohibition of Access to Reserved Addresses
Access to reserved addresses is prohibited.
The reserved addresses are provided for the possible future expansion of functions. Do not
access these addresses; the correct operation of LSI is not guaranteed if they are accessed.
4. Clock Signals
After applying a reset, only release the reset line after the operating clock signal has become
stable. When switching the clock signal during program execution, wait until the target clock signal
has stabilized.
When the clock signal is generated with an external resonator (or from an external oscillator)
during a reset, ensure that the reset line is only released after full stabilization of the clock
signal. Moreover, when switching to a clock signal produced with an external resonator (or by
an external oscillator) while program execution is in progress, wait until the target clock signal is
stable.
5. Differences between Products
Before changing from one product to another, i.e. to a product with a different part number, confirm
that the change will not lead to problems.
The characteristics of Microprocessing unit or Microcontroller unit products in the same group
but having a different part number may differ in terms of the internal memory capacity, layout
pattern, and other factors, which can affect the ranges of electrical characteristics, such as
characteristic values, operating margins, immunity to noise, and amount of radiated noise.
When changing to a product with a different part number, implement a system-evaluation test
for the given product.
