3. Troubleshooting (Action in Case of an Error)

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
the emulator and the user system have been powered on. For the latest information on the emulator and emulator
debugger, visit Renesas Electronics' development environment website (http://www.renesas.com/tools).

3.1.1. ACTION LED does not light

(1) Keeps flashing
The USB driver is not installed correctly in the host machine.
Install the USB driver correctly.
(2) Remains off
This means that the E1 or E20 is in an unusable state for some reason. Check the following:
• Whether the E1 or E20 and the host machine are connected with the USB interface cable.
• Whether the power switch of the E20 is turned on.
• 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 MCU.
For details, consult the separate E1/E20 manual for the MCU you're using.
• Whether the emulator and the MCU 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 MCU is in a ready state.
• The MCU operating clock is on (= oscillating).
• The MCU is supplied with power properly.
• The MCU has been reset and is ready to go.
