CONFIG Section (Compact 2013)

  • Article

3/26/2014

The CONFIG section is optional. The CONFIG section does not need to be in the .bib file, and CONFIG section entries do not have to be in any order.

Romimage.exe always produces a .bin file, whether you define an .abx entry, an .sre entry, or a CONFIG section.

To create an .sre or an .abx version of the binary ROM image, update the CONFIG section of the file Config.bib.

For more information about run-time image data formats that you can specify, see Run-Time Image Configuration Files.

The Jump Page

Several configuration options, such as BOOTJUMP, affect the jump page, which contains instructions that the device uses to jump to the code that starts the run-time image.

By default, the jump page is at the lowest address in memory within the RAMIMAGE space.

Writable Sections

Some configuration options refer to a writable section. A writable section of a module contains the module's global variables which are writable at run time. Because this section is writable, it must be copied from ROM or flash memory into RAM when the module is loaded.
