about the
.vector
section
The
.vector
section is an exclusive section provided by the
IDE
to ensure that vector tables will always be
located beginning with the trap table vector address.
With the initial IDE settings, the
.text
section is located immediately after the
.vector
section.
By specifying a file that includes a vector table as the object to be located in this section, it is possible to en-
sure, without concern for the order in which this and other objects are located, that the vector table will always
be located from the above address.
The object to be located in this section can be selected in the wizard for creating a new project. For more infor-
mation on this wizard, refer to Section 5.4.2, "Creating a New Project".
Select the object you want to locate in the
.vector
section from the combo box list (
vector.o
and
boot.
o
selectable) or by entering it in the combo box text field.
Use the [Set boot vector address] text box to specify the address to locate the
.vector
section. The setting
address depends on the model of the [Target CPU Device] (e.g., 008000, 020000, etc.). 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.
If you do not locate objects in the
.vector
section, deselect the [Allocate a specific file to '.vector' section]
check box. Even so, the
.vector
section is defined as a section, but without an object.
The contents set in the wizard can be changed in the [Edit Section] dialog box (refer to "Editing section infor-
mation").
