2.5 Connecting System Ground

The emulator's signal ground is connected to the user system's signal ground. In the emulator, the signal ground and frame ground are connected. In the user system, connect the frame ground only; do not connect the signal ground to the frame ground (Figure 2.5). If it is difficult to separate the frame ground from the signal ground in the user system, set the GND for DC power input (AC adapter) of the host machine and the frame ground of the user system as the same potential. If the GND potential is different between the host machine and the user system, an overcurrent will flow in the low-impedance GND line and thin lines might be burned. WARNING Connecting System Ground : Separate the frame ground from the signal ground at the user system. Failure to do so will result in smoke, fire, or an electric shock due to the difference in ground potential. Figure 2.5 Connecting System Ground For a debugging environment where there is a difference in potential between the GND of the user system and that of the host machine, use the isolator (R0E000010ACB10 or R0E000010ACB20) which is separately available from Renesas.

2.6 Hot plug-in

By using the optional hot-plug adapter for E1 emulators (R0E000010ACB00) which is separately sold, the hot-plug-in function which connects the E2 Lite to the user system is available while the user system is supplied with the power and in operation. For information on the hot plug-in-function, be sure to read the latest version of a user's manual provided for each MCU group.

3.1 How to Solve a Trouble

The following describes how to solve a trouble when any problem occurs before the emulator debugger starts after power has been supplied to the emulator and the user system. For the latest information on the emulator and emulator debugger, visit Renesas Electronics’ development environment Web site (http://www.renesas.com/tools).

3.1.1 The ACTIVE LED does not flash or light up

(1) Power is turned off This means that the E2 Lite is in an unusable state for some reason. Check the following:  Whether the E2 Lite and the host machine are connected with the USB interface cable.  Whether the power for the host machine is turned on.

3.1.2 Unconnectable with the debugger

(1) Check the connection between the emulator and the target MCU. For details, refer to the additional document for user’s manual for the E1/E20 emulator or E2 emulator Lite which corresponds to the target MCU.  Whether the emulator and the target device are connected correctly.  Whether the connected signal lines are pulled up to the power supply or down to GND properly. (2) Check to see that the target MCU is in a ready state.  The operating clock of the target MCU is on (= oscillating).  The target MCU is supplied with power properly.  The target MCU has been reset and is ready to go.

R20UT3240EJ0300 Rev.3.00 Page 28 of 36 May.15.20 Appendix A E2 Lite Self-Checking Program (SCP) This chapter gives the procedure for using the self-checking program (SCP) for the E2 Lite in fault analysis. A.1 Flow of Self-Checking Install the emulator software, the USB driver, or the E2 Lite SCP. Install the SCP and USB driver for the E2 Lite on the host machine (this step is only required first). Connect the USB interface cable*. Connect the USB interface cable to the USB connector of the host machine and the E2 Lite and turn on the power for the emulator. Initiate the E2 Lite SCP. Initiate the E2 Lite SCP. Start the TEST1 and TEST2 programs. Start the TEST1 and TEST2 programs. View the results of self-checking. If the results were normal, “PASS” will be displayed. If checking indicated a failure, “FAIL” will be displayed. In the case of “FAIL”, a further error message is also given. For the messages and their meanings, see Table A. 1. Note: Fault analysis of the hardware by using the E2 Lite SCP only works correctly when a single emulator is connected to the host machine. When two or more emulators are connected, correct operation is not guaranteed. A.2 Preparations for Self-Checking (1) The following items are required to execute the E2 Lite SCP.

• E2 Lite main unit
• USB interface cable (included in the package)
• Host machine
• E2 Lite SCP (self-checking program) Install the E2 Lite SCP to the host machine by installing an integrated development environment from Renesas (e.g. CS+) or downloading the E2 Lite SCP installer from the following Web site. https://www.renesas.com/e2lite_download The USB driver is included in the installation of the integrated development environment from Renesas (e.g. CS+ or the e2 studio). If you are using an integrated development environment not from Renesas, please contact a Renesas Electronics representative or distributor. (2) Start up the host machine. Connect the USB interface cable to the USB connector of the host machine and the E2 Lite and turn on the power for the E2 Lite. The user-system interface cable is not used.

R20UT3240EJ0300 Rev.3.00 Page 29 of 36 May.15.20 A.3 Executing the SCP (1) Execute the E2 Lite SCP (E2Lite_SCP.exe). When CS+ has been installed, open the start menu and select [Programs] -> [Renesas Electronics CS+] -> [E2 Lite Self Check Program]. If you are using any other debugger product, install the SCP by using the installer of the SCP that has been downloaded from the E2 Lite downloading site, then open the start menu and select [Programs] -> [Renesas Electronics Utilities] -> [E2 Lite Self Check Program]. Figure A.1 Starting the E2 Lite SCP (2) Click on the [START] button to start the SCP. Do not enter any value in the [CODE] textbox since it is not used at this stage.
