An apparatus and method for stabilized binary differencing are provided. The method includes obtaining a first report file for a first image corresponding to a current firmware version and a second report file for a second image corresponding to an updated firmware version, each report file containing information about a plurality of sections of the corresponding image, generating a first object array corresponding to the first report file and a second object array corresponding to the second report file, comparing the first object array to the second object array, updating the second object array to reflect the results of the comparison, generating a steering file based on the updated object array, performing a binary differencing on the first image and the second image based on the steering file, and generating a delta file based on the binary differencing.

Stabilized binary differencing

Techniques directed to an update package including a set of instructions used for, in a remote client device, creating a new data image from a base data image are provided. A method for generating an update package includes determining differences between a base data image and a new data image, generating COPY instructions corresponding to respective sections of code in the base data image, organizing the COPY instructions into a directed acyclic graph, performing cycle detection on the COPY instructions in the directed acyclic graph to detect any cycles, when a cycle is detected, identifying a COPY instruction in the detected cycle with a smallest overlapping part, removing the overlapping part from the identified COPY instruction, and generating a COPYBACK instruction including the overlapping part removed from the identified COPY instruction, and after all cycles have been detected, generating the update package based on the COPY and COPYBACK instructions.

The present disclosure relates generally to a system and method for change logging in a firmware over the air (FOTA) development environment. In one example, the method may include creating a cumulative change log for an intermediate binary file that contains an extractable binary image. The cumulative change log may record changes between the intermediate binary file and earlier iterations of the intermediate binary file. The cumulative change log may be stored in the intermediate binary file and later retrieved. The cumulative change log may be analyzed to identify statistics about changes that occurred between the intermediate binary file and earlier iterations of the intermediate binary file.

The present disclosure relates generally to a system and method for a pseudo DLL linker. In one example, the method includes identifying a plurality of components forming an image and identifying all symbols exportable from each component and all symbols imported by each component from another component. A redirection mechanism is built containing an address of each symbol exported by a component that is imported by another component, and each component is modified to alter each direct reference to a symbol associated with another component to a reference to the redirection mechanism. A linker is called to link a final image based on the modified components.

A supplementary power supply for a peripheral device is provided. The supplementary power supply comprises a first connector, a second connector, a power source, and a path. The first connector is operable to couple to a host device. The second connector is operable to couple to the peripheral device. The power source is operable to provide electrical power to the peripheral device via the second connector. The path is operable to allow data to pass between the host device and the peripheral device. A method for providing electrical power to a peripheral device is also provided.
