Specifying a target CPU
Step 6
: From the [Target CPU Device] combo box, select the target processor. Here, se-
lect "S1C17".
Selecting a memory model
Step 7 : Select the memory model supported by the processor from the [Memory Model]
combo box. Here, select "REGULAR".
REGULAR: 24-bit address space (16MB)
MIDDLE: 20-bit address space (1MB)
SMALL: 16-bit address space (64KB)
Selecting a coprocessor library
Depending on the selected target CPU, you can specify whether to link a coprocessor library and its type.
Step 8 : Select or unselect the [Use Co-processor Library] checkbox.
ON: Adds the setting to link the coprocessor library libgccMD.a (for multiplication and division)
or libgccM.a (for multiplication) when creating a project. If you select this option, select the
library type from the [Select the Co-processor library type] combo box. (Certain models offer
just one selection option.)
OFF: Adds the setting to link the ordinary emulation library libgcc.a when creating a project.
Specifying a vector table file
The
IDE
requires the definition of a vector table section labeled
.vector
in a linker script to ensure that the
trap vectors located in memory always begin with the trap table base address. In the [Use '.vector' section as a
vector table container] field of this screen, specify whether to locate a specific object in the
.vector
section
by selecting or unselecting the check box and set an object file name in the combo box. Here, we'll proceed as-
suming that
boot.o
is located in the
.vector
section.
Step 9 : Select
boot.o
from the pulldown list.
For detailed information on the
.vector
section, refer to Section 5.7.8, "Editing a Linker Script".
Specifying a boot vector address
In the [Specify boot vector address] field, specify a boot vector address. The default boot vector address is
"008000". The value set here will be used as the parameter for the TTBR setting command that will be written
in the debugger startup command file created by the
IDE as well as it will be used as the VMA of the
.vector
section that will be written in the linker script file. It is not necessary to alter the default value.
