Abstract
A system and method are provided for organizing field upgradeable system software in a wireless communications device. The software is organized into a first plurality of symbol libraries or code sections. Contiguously addressed memory blocks store the symbol libraries or code sections. The start addresses of code sections or symbol libraries are stored in a code section address table cross-referencing code section identifiers with corresponding start addresses. Each symbol is offset from its respective code section start address. Symbol identifiers are cross-referenced with corresponding offset addresses, and corresponding code section identifiers in a symbol offset address table. A symbol accessor code is used to identify symbol addresses using the code section address table and the symbol offset address table.
