studio version
2. DK-S7G2 Kit
This programming guide applies to Version 3.0 of the DK-S7G2 Development Kit. The out-of-box demo that we load may be a newer and improved version compared to the factory installed demo.
3. Reload the out-of-box demo
Follow these steps to reload the out-of-box demo into the development kit.
1) Set the JTAG DIP switch 6 on S5 to ON (toward the LEDs).

2) Verify all of the S101 DIP switches on the Breakout Board are set to OFF.
3) Using the power supply provided with the DK-S7G2 Kit and apply power through the 5V barrel connector
(J1) on the Main Board. LED3 will turn on yellow with a red LED flashing below it. The yellow/red flashing
LEDs informs the user that the kit cannot communicate with the PC on the debug port.
4) Connect the USB cable provided with the DK-S7G2 J-Link OB (J17) on the Main Board.

5) Connect the other end of the USB cable to a USB port of the PC. Now LED3 will turn green, indicating a good connection.
6) In Windows Explorer, double click on “Program DK-S7 OOB Demo.bat” to program the kit using JLink.
NOTE: If the update J-Link firmware dialog box is displayed, we highly recommend that you click Yes.
Programming failure may occur if you update the firmware. If this happens, just double click on the .bat file again.
The out-of-box demo application is now loaded onto the DK-S7G2 board and the board is automatically reset.
4. Out-of-box demo notes
1) During initialization, the S7G2 MCU turns on the LEDs that it can control (Red and Green). The MCU also turns on the Red LEDs inside the Ethernet connectors, so you can verify the Ethernet connections work. At the end of initialization, LED1 and LED2 are off while the Configuration LEDs, LED6 to LED12 are green.
2) A splash screen is displayed on the LCD showing a date and time.

3) Press anywhere on the splash screen to go into the Thermostat Demo.
4) Press Settings on the top right.
5) Go into Units, Display, Set Time, Set Date and Sound to make adjustments to the demo.
6) Click on the left side of the Thermostat main screen to enter the Thermostat Control Menu.
7) Within the Control Menu, adjust the System, Fan, and Temperature and review the Help screen (shown below).

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.
