The .vector section is defined with the .rodata attribute. Make sure the vector table is written in the
source files, as shown below.
For C sources (vector.c)
For assembler sources (boot.s)
Declare a vector table with const to specify that it be located in the .rodata section.
Example:
Declare a .rodata section and write a vector table following it.
Example:
If you are using an assembler source in which a vector table is written in the .text section and you want
the table to be located in the .vector section, select the desired method from the following options:
Method 1: Editing the source file
Method 2: Editing section information in the IDE (using the source file as is)
If you are not using the .vector section, deselect the [Allocate a specific file to '.vector' section] check
box and edit the .text section in the [Edit Section] dialog box to locate boot.o at the top.
