Abstract: Various embodiments include methods and devices for implementing external paging and swapping for dynamic modules on a computing device. Embodiments may include assigning static virtual addresses to a base image and dynamic modules of a static image of firmware of the computing device from a virtual address space for the static image, decompose static image into the base image and the dynamic modules, load the base image to an execution memory during a boot time from first partition of a storage memory, reserve a swap pool in the execution memory during the boot time, and load a dynamic module of the dynamic modules to the swap pool from a second partition of storage memory during a run time.

Abstract: Embodiments of the present disclosure include systems and methods for efficient over-the-air updating of firmware having compressed and uncompressed segments. The method includes receiving a first update to the firmware via a radio, wherein the first update includes a first uncompressed segment and a first compressed segment, receiving a second update to the firmware, wherein the second update corresponds to the first compressed segment, compressing the second update to generate a compressed second update, applying the first update to the firmware, and applying the compressed second update to the firmware to generate an updated firmware.
