Choose Command Line from the View menu and open the Command Line window.
When downloading the load modules, activate the Command Line window to check whether the script file is running.
Note: Unless the script file is running, you cannot download the load modules into the flash memory. So be sure to

5.3 Adding/Modifying Hardware Setup Files
For the software to be run on the SH7670 CPU board, the hardware dependent part of the SH7670 CPU board must
be set up.
Here, the hardware dependent part of the SH7670 CPU board is added or modified for the standard source files that
were automatically generated when you created a new project. The procedure for adding/modif ying hardware setup
files is described below.
The setting of the hardware dependent part indicat es the settings of external memory (flash memory, SDRAM)
access timing, the operating clock and the cache memory.
5.3.1 Copying Hardware Setup Files
Copy “HardwareSetup” directory from the CD-ROM into the directory for the new project workspace
"C:¥WorkSpace¥test" that you created previously.
The explanation given below assumes that the hardware setup files are stored in
"
C:¥WorkSpace¥test¥HardwareSetup" directory.

5.3.4 Setting Compiler Options
From the Build menu, open [SuperH RISC engine Standard Toolchain] dialog box and open [C/C++] tab. On this tab,
set “Category”, “Show entries for” and “Options C/C++” as necessary.
For details on how to set “Option C/C++”, refer to the manuals for SuperH RISC engine C/C++ compiler, assembler
and optimization linkage editor.
In the installation described here, because the include files for the hardware dependent part of the SH7670 CPU
board are stored in a separate directory other than the default proj ect directory, you ne ed to set an additional relative
path to the include file directory.
• Default project directory:
• Directory in which the include files are stored:
The following shows how to set a relative path to the include file directory.

To use the io_init_cache function (that sets cache memory), the section for it must be loc ated in the non-cacheabl e
area of CS0. The following shows how to set up the section to the non-cacheable area of CS0.
For the details about cache memory, refer to the chapters of cache and BSC in SH7670 group hardware manual.

(c) Setting example for section in case for forwarding vector table section DINTTBL to on- ch ip RAM
Interrupt response speed can be sped up by forwarding vector table to on-chip RAM, and using register bank.
Forwarding vector table sets the vector table section on ROM as DINTT BL, and sets the section on RAM for the
forwarding destination as RINTTBL with "dbsct.c" added by 5.3.3.
<Section definition for vector table>
• Section name of vector table (ROM section): DINTTBL
• Section name of forwarding destination (RAM section): RINTTBL
The following shows the section setting procedure to modify the DINTTBL section from ROM to on-chip RAM
in the sample program.
(1) Set the RINTTBL section to on-chip RAM area in [Section] dialog box as shown in
<Example for adding section to on-chip RAM area>
“Address”: 0xFFF80000
“Section”: RINTTBL
Note: When the address above is set, the vector base register of CPU should be set. In the sample software,
the vector base register should be set inside the reset exception handling in the resetprg.c file.

5.3.6 Writing the Main Function (Operation Confirmation)
In the main function (test.c source file), write a program to turn on the LED (LED7 on the SH7670 CPU board lights up).
• Open the source file C:¥WorkSpace¥test¥test¥test.c with an editor, etc.
• Write the program that is shown below to turn on the LED.
