5.2.2 Control on Combining and Locating Sections
Section 5.2.2 describes those linker functions used to control combining and locating
sections.
■ Specifying ROM and RAM areas
Defining an area name by specifying the address range of the ROM and RAM areas allows you to use this
area name instead of an address when specifying where to locate a section. It also allows you to make sure
that the section is not located outside the range.
To have sections automatically located, locate them in this area range.
■ Specifying the Order of Locating Sections and the Location Addresses
All the sections may be located in any area in any order. To specify a section name, use a wild card.
Additionally, you can specify sections using a name plus a section contents type. Use these together with a
wild card to collect only the sections with the same contents type (code, data, etc.).
■ Creating a Group of Sections
A linker combines and locates sections. If many sections are used to create a program, specifying where to
locate the sections will be troublesome.
Multiple sections may be handled as if they are one section by giving them a group name and collecting
them in continuous areas.
■ Support for Creating a ROM
When developing a program in C/C++, a variable with an initial value is created. The variable must often
be rewritten and other processing must be performed.
In an application to be imported, the initial value data must be placed in ROM and transferred to RAM
before the application is executed.
This function enables these operations. For details, see Section "5.9 Sections to be Transferred from ROM
to RAM".
