System and method for organizing wireless communication device system software
First Claim
1. A wireless communication device comprising:
- a nonvolatile memory module comprising;
a file system section (FSS) for storing a received updated code section and a received updated patch manager code section;
a code storage section for storing a plurality of code sections, each code section of the plurality of code sections comprising at least one symbol library comprising a plurality of symbols having a related functionality; and
a patch manager code section configured to overwrite at least one of the plurality of code sections comprising;
a code section address table which stores a code section identifier and a start address for the each code section; and
a symbol offset address table which stores an offset reference for each symbol of the plurality of symbols in the at least one symbol library stored in the each code section, the offset reference comprising an offset value derived from the start address of the each code section,wherein the patch manager code section is configured to control a system software update in response to a user acknowledgement that resets the wireless communication device, the system software update including copying a patch manager code section stored in the nonvolatile memory to a volatile memory notifying a user via a user interface that an updated code section and an updated patch manager code section has been received, receiving an acknowledgement from the user, suspending a communication task for the wireless communication device, overwriting at least a portion of a code section of the plurality of code sections with the updated code section and overwriting at least a portion of the patch manager code section with a portion of the updated patch manager code section by updating the code section address table and updating the symbol offset address table.

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.

7. A method for updating system software in a wireless communications device, the method comprising:
-
copying a patch manager code section stored in a nonvolatile memory to a volatile memory; receiving a broadcasted system software update comprising an update code section and an update patch manager; notifying a user via a user interface that the wireless communication device has received the broadcasted system software update; receiving an acknowledgement from the user via the user interface; initiating an update operation in response to the acknowledgement, the update operation comprising, (1) suspending a communication task for the wireless communication device; (2) storing the system software update on a file system section of the nonvolatile memory, (3) overwriting at least a portion of a code section of a plurality of code sections stored in a code storage section of the nonvolatile memory with the update code section, each code section of the plurality of code sections comprising at least one symbol library, having a plurality of symbols of related functionality, (4) overwriting at least a portion of a patch manager code section of the nonvolatile memory with at least a portion of the update patch manager, comprising, updating a code section address table of the patch manager code section which stores a code section identifier and a start address for each code section of the plurality of code sections, updating a symbol offset address table which stores an offset reference for each symbol of the plurality of symbols in the at least one symbol library of the each code section, the offset reference comprising an offset value derived from the start address of the each code section, and (5) resetting the wireless communication device. - View Dependent Claims (8, 9, 10, 11, 12, 13)
