Console Swap Demonstration
Synergy
Description: This demonstration illustrates on of the key advantages of the Synergy Platform in
accelerating time to market and similifying development. SSP Frameworks use common interfaces that
make it very easy to swap in and out different versions of hardware based implementations. In this
demonstration a simple user interface Console will be quickly modified to switch between a USB
communications implementation and a Telnent communications implementation.The swap is easily
accomplished without writing any code since the Console Framework uses common API and structures
between the USB Communications Framework and the Telnet Server Communications Framework.
Demonstration Objectives
1. Illustrate, using a hands-on example,
how easy it is to modify Synergy
Platform designs for different
hardware implementations

1 Setup & Configure DK-S7G2
Procedural Steps
Step 1.1 Connect the DK-S7G2 (Figure 1) to power, the Seeger J-Link OB Debug port to the laptop and
the USB Console port to the laptop (Figure 2). Driver recognition for the console connection
isn’t found until the DK-S7G2 is running, so don’t worry if you don’t hear the audio indication
yet.

Once the Power and J-Link OB are connected to the DK-
S7G2, LED3 should be a solid Green. If LED3 is flashing and the J-
Link OB is connected to the correct USB port on the DK-S7G2, then
the Segger driver on the host computer is incorrectly installed. Refer
to the ISDE installation guide to resolve the issue.
Step 1.2 Turn ON the ‘JTAG’ switch, and the ‘ENET1’ switch on S5 on the main board (Figure 4).
Make sure all other switches are in the off position.

Step 2.3 Select the ‘Select archive file’ radial button and click browse. Locate the ConsoleSwapUSB
zip file. Make sure the check box is selected and click ‘Finish’. (If this project name already
exists in your workspace, you won’t be able to select the check box. You will need to remove
that project in order to import).

Step 2.4 To confirm the correct Synergy license, right click the project in Project Explorer. Select
‘Properties’ in the pop up menu. Type ‘License’ into the search bar on the left of the window
and click on ‘Synergy License’. Select the navigation button to the right of the ‘License file’
drop down menu and navigate to the address below. Once your correct license file is selected,
click ‘Apply’ and then ‘OK’. (An example location and file name is given below).
C:\Renesas\e2_studio\internal\projectgen\arm\Licenses\SSP_License_Example_EvalLicense_20151120.xml
Step 2.5 Once the project is open, double-click the ‘configuration.xml’ file as shown below to open the
Synergy Configuration tool.

Step 2.6 Build the project. It sould compile without errors. (Note that some warnings may exist. You can
ignore these). Run the debugger. (If you need to create a debug configuration file, you can
create one by selecting Run > Debug Configurations, then double click Renesas GDB
Hardware Debugging, select the executable file from the Debug folder, and on the Debugger
tab, select target device R7FS7G2. Click Debug to begin a debugging session).
Step 2.7 Click on the Run icon a couple of times to get the program to begin executing. You should get
an audio indication that the Console USB connection has been recognized. (Open Device
manager to check that your Console USB connection is active and find the corresponding
COM port for use with the TeraTerm session).
Step 2.8 Start-up Tera Term. You should be able to select the Serial Interconnect session with the right
COM port and then connect. Type a carriage return and you should get the console prompt
and if you then type a “?” you will get the help menu as seen in the following figure.

Step 2.9 Type in “TOGGLE” to toggle the LED on the DK-S7G2. Type it a few times to verify the toggle
works. Note that you can use an up arrow to ‘replay’the previous command. This feature is
supported automatically within the console framework.

3 Configure the Telnet Communications Interface
Procedural Steps
Step 3.1 Go to the ‘Threads’ tab of the Synergy Configuration tool and select the Console Thread.
Step 3.2 Select the Thread Modules associated with the USB Communications stack as shown below.
Click Remove.

Step 3.3 Now add the Telnet Communciations Framework by selecting New/ Framework/ Connectivity/
Communications Framework on sf_el_nx_comms. By hovering over this selction you will see
the additional modules that need to be added. Select the g_sf_comms module and in its
parameters window change the Channel from 0 to 1.
Step 3.4 Add the additional modules required to complete the implementation of the Telnet
communications framework. These are:
Framework/ Networking/ NetX Telnet Server on nx_telnet_server
Framework/ Networking/ NetX on nx
Framework/ Networking/ NetX Port ETHER on sf_el_nx
oSet the required interrupt to Priority 0.
Step 3.5 The above actions should clear all configuration issues. Save the configuration. Build the
debug configuration. This should build without Errors.
Step 3.6 Remove the console USB cable (This is the one closer to the Ethernet connector.) and plug in
the Ethernet cable from the main board Ethernet port to the Laptop. If your laptop Ethernet
port hasn’t already been configured for Telnet operation, do this now. Refer to Appendix 1 for
a more detailed procedure if you are unfamiliar with how to make any of these changes.
Disable your wireless connection
Enable your wired Ethernet connection
Set a static IP address on the same subnet of the statically assigned IPV4
address of the board (The board address is 192.168.0.0, so you could set your
Ethernet port to 192.168.100.100 with a subnet mask of 255.255.0.0).
Step 3.7 Run the debugger and click on the Run icon a couple of times to get the program running. The
LEDs indicating an active Ethernet Connection shuld now light up. Now, connect with
TeraTerm using the settings of 192.168.0.0; Telnet Service; and the default settings for TCP
port (23), SSH and Protocol (UNSPEC) as seen in the figure below.

Step 3.8 You should be able to get the Telnet console window after hitting Enter in the terminal window
as seen in the figure below. Type in the TOGGLE command a few times to see the LED blink.
When finished exit the debugger.

4 Appendix
This appendix provides detailed descriptions of how to set-up the console PC to use the Ethernet Port for
a Telnet session over TeraTerm. This process is for Windows 8, but should be similar for other versions
of Windows.
Procedural Steps
Step 4.1 Go to the Control Panel and select the Network and Sharing Center. Click on Change Adaptor
Settings. You will get a list of Network Connections similar to those shown in the figure below.
Step 4.2 If the Wireless Adaptor is enabled, you need to disable it. Select the Wireless Adaptor and
Right click on it. Select Disable.
Step 4.3 Select the Ethernet port you will use for the Console. Right click and open properties. Scroll
down and select Internet protocol Version 4 (TCP/IPv4). Refer to the figure below. Select
Properties. Select Use the following IP address and enter in 192.168.100.100 into the IP
address filed. Enter 255.255.0.0 into the Subnet mask field. Cick OK. Click OK in the Ethernet
Properties window. Close the Ethernet Status window, if open. Your Ethernet port should now
be configured to work with TeraTerm as a Telnet connection. You will need to reverse this
process to disable your wired Ethernet connection and Enable your wirless connection after
you are done with the demonstration.
