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.
