The generated file will be the debug target.
Sample startup programs are not generated when the project is created.

-

Boot Loader for Multi-core(CC-RH)

Select this to create a boot loader project for multi-core, by using build tool CC-RH provided by CS+.

A boot loader project is used to set application projects configuring a project for multi-core.

Caution

This item is displayed only when microcontrollers for RH850 multi-core are selected in "(2) Select the microcontroller".

Remark

The following start-up source files are generated in the project folder.
These files are also registered in the project tree.

Caution

This item is displayed only when microcontrollers for RH850 multi-core are selected in "(2) Select the microcontroller".

Remark

The following start-up source files are generated in the project folder.
These files are also registered in the project tree.

File Name

Description

cstartn.asm

Library(CC-RH/CC-RX/CC-RL)

Select this to generate a library file for a user library, by using the build tool provided by CS+.

-

Debug Only

Select this to debug a load module file or hex file generated with a build tool other than the one provided by CS+ (i.e. creates a debug-dedicated project).
See "E. USING AN EXTERNAL BUILD TOOL" for details on how to create and use the debug-dedicated project.

(4)

Specify the project name and location to create the project file

Specify the name of the project and the location to create the project file in [Project name] and [Place].

If you don’t create a folder with the project name under the specified location, clear the [Make the project folder] check box.

Caution 1.

When directly entering the location to create the project file, enter it as an absolute path.

Caution 2.

The name of a network path cannot be used for [Place]. Assign the name of a path on a drive.

Remark

It is recommended to specify the same folder as the diverted project for the location to create the project file.
If a folder different from the diverted project is specified, there is a possibility that path determination fails and a build error is occurred.

(5)

Specify the reuse of the file structure of an existing project

When creating a project that reuses the file structure of an existing project, check [Pass the file composition of an existing project to the new project] and specify the location of the project filename to reuse in [Project to be passed].

Caution 1.

You cannot specify an e2 studio, CubeSuite, High-performance Embedded Workshop, or PM+ project file.
If you wish to copy an existing e2 studio, CubeSuite, High-performance Embedded Workshop, or PM+ project, open the project in CS+, then save it as a CS+ project (see "2.4.10 Convert an e2 studio project into a CS+ project [RX][RL78]", "2.4.11 Convert a CubeSuite project into a CS+ project", "2.4.12 Convert a HEW project into a CS+ project", "2.4.13 Convert a PM+ project into a CS+ project" for details). Next, specify the saved project file in this area.

Caution 2.

When you create a project, only the settings for the default debug tool will be imported.
In the RX family, however, internal processing is common to the emulator and simulator, so the settings are imported regardless of which debug tool is selected.

Remark 1.

When the version of the build tool used in the source project is different from the version of the build tool in the project to be created, it is automatically diverted (the case that "Debug Only" is specified with [Kind of project] is excluded).

 

An image of the dialog box after setting the items is shown below.

Figure 2.7

Create Project Dialog Box (After Setting Items)

 

When you click the [Create] button, the project file is created in the location specified in (4) and the structure of the created project is displayed as a tree in the Project Tree panel.

Remark

After creating a project, you must add target files to the project in order to perform building or debugging.
For details on how to add these files, see the following.

-

When "Application" or "Library" is selected on [Kind of project]

-> See the "2.6.1 Add a file to a project"

-

When "Debug Only" is selected on [Kind of project]

-> See "E.3 Add a File to a Project"
