A linker profiler tool facilitates maintenance and management of object ordering between releases of firmware. By maintaining object ordering, code differences between firmware builds are reduced, which reduces the size of a package of update information used to update an electronic device from one version of firmware to another. Information used by an object code linker in a firmware build activity is processed to minimize changes in code object ordering between builds. The impact on the size of the update information caused by updates to firmware/software component in the build is thereby reduced to a minimum.
