 Multiple related projects created in each Workspace

 Projects of selected workspace presented in Project Explorer

view

 One project per application under development

 Workspaces also store global e2Studio preferences

 Avoid workspace paths containing spaces

 Launch from workbench File menu or Project Explorer

context menu

 Select the C Project or C++ Project wizard from the tree

 C project wizard for C source code application

 C++ project wizard for C and/or C++ code application

Project Wizard

Trang 20

Project Name, Type and Toolchain

 Enter new project name

 Select Executable (Renesas)

>> Sample Project type

 New project will include

startup code and skeleton

main()

 Project builder will generate

a fully linked application

 Select toolchain

 Toolchain architecture will

influence subsequent wizard pages

Trang 21

21

Target-Specific Settings

 Select toolchain version if multiple versions installed

 Select CPU series, type

and endianness where

applicable

 Selections may affect

processor instruction set

 Critical for correct

execution on target hardware

 Select other CPU options

Trang 22

Library Generator Settings

 Select library source

 Newlib library – complete

ISO C library supporting C/C++ code

 Optimized library – subset

of ISO C library supporting

C code

 Select required library

modules

 Select library generation

 Pre-built for convenience

 Project-built for

source-level debugging

Trang 23

23

Default Debug Settings

 Select default debug mode

 Hardware Debug

– debug probe and target device must be specified

Trang 24

e2Studio Project Layout

 Project source files typically located

Trang 25

25

Project Editing

 Create new source files via context menu wizards

 New >> Source File – for C or C++ files (*.c, *.cpp)

 New >> Header File – for header files (*.h, *.hpp)

 New >> Source Folder

Trang 27

27

C/C++ Managed Build System

 All source files under src folder are built

 C source (*.c)

 C++ source (*.cpp)

 Assembly source (*.asm)

 Select active build configuration prior to build

 Build on demand via workbench menu items

 Project >> Build Project (builds currently selected project)

 Project >> Build All (builds all projects in workspace)

 Monitor build progress in Console view

 Review build issues in Problems view

 Double click to open related source code in C/C++ Editor

 Build options

 Build Automatically (not recommended for C/C++)

 Save automatically before build

Trang 28

Extended Project Properties

 Toolchain-related properties specific to a project or file

 First select a project or file in Project Explorer

 Project >> Renesas Tool Settings

 Code generation, linking and archiving options

 Standard C library generation and usage options

 Linker script editing

Trang 29

e2Studio Launch Configurations

 One launch configuration per application and per debug target

 Encapsulates all launch-related parameters

 Launch type (hardware or simulator)

 Application executable file

 Connection parameters

 Debug probe details

 Launch configuration for default debug mode generated by project wizard

 Other configurations generated on initial launch within

e2Studio

 Customization possible but seldom necessary

 Run >> Debug Configurations

Trang 34

Launching e2Studio Debug Sessions

 Specify launch type at point of launching

 First select a project or executable file in Project Explorer view

 Run >> Debug As >> Renesas GDB Hardware Launch

 Run >> Debug As >> Renesas GDB Simulator Launch

 Open Renesas Debug Perspective

 Alternative presentation of views within Eclipse workbench

 Views for inspection and manipulation of target state

 Standard CDT views updated when execution suspends

 C/C++ editor presents source code at program counter

 Variables (local variables only)

 Expressions (including global variables)

 Registers

 Memory

Trang 35

35

Renesas Debug View

 Control execution of code on target

 Select stack frame to inspect related local variables

 One active debug session only

 Terminate any existing session before launching another

 Use Reload to avoid termination within edit/build/debug cycle

 Challenge:

“MCUs continue to become more complex especially when creating applications to enable the Smart Society, and

therefore the tools become more complex as well As a

result we must create tools that enable complete debug

capability at minimal cost.”

 Solution:

“OpenSource IDE’s with custom layers must be developed to enable engineers to create applications for the 2010’s”

Do you agree that we accomplished the above statement?
