Challenge:

MCUs continue to become more complex especially whencreating applications to enable the Smart Society, andtherefore the Software becomes more complex as well. As aresult Project schedules do not always scale accordingly andrequires tips and tricks from the MCU supplier to configure

the MCU which works best with the application.

Solution:

This class provides tips and tricks for how to configure theRenesas new IDE Eclipse with GNU compiler to quickly develop

RL78 application.

Definition of Terms

Software Elements

e2studio Eclipse based Integrated Development Environment forRenesas Microcontroller families RL78, RX, V850, SH.

Perspective A perspective is like a page in a book which contains set ofviews.

DebugPerspective



Definition of Terms (Cont.)

Software Elements (cont.)

View: A perspective consists of a number of sub-windows, calledviews.

Option Byte: Four bytes which configure the RL78 at boot-up.

Security ID: A 10 bytes code provides on-chip debug security IDto prevent third parties from reading RL78 memory content.

Hardware Elements

TK interface On-chip debug emulator for RL78 device.

RDK Renesas Demonstration Kit

Common Issues

Can t find the TK interface under hardware debugconfiguration in e2studio?

-> There is no TK interface options available in the e2studio .E1 debug option serves for both TK interface and E1emulator connection.

I started the debugger but cant see the code on the debugwindow?

-> Check if you have switch to the debug perspective from theC/C++ perspective.

Cant connect e2studio to RDK board for the debug session?

-> Check the SW5 DIP-switch setting on the board as:

1:OFF; 2:ON; 3:OFF ; 4:OFF
