摘要： Systems and methods are provided for static file system (SFS) differencing and updating. The differencing and updating includes portion-level differencing and block-level updating of units of an original image (referred to as blocks). The differencing and updating splits SFS images into portions based on block information and the image structure. A delta file is generated for each portion (portion-level differencing) of the new SFS image; the delta file includes information of differences between the portion of the new SFS image and the portion of the original SFS image to which the new SFS image portion corresponds. The delta files are transferred to a device where the target SFS image of the device is updated block-by-block using information of the delta files. The block-by-block update reconstructs all portions of the new SFS image in a device block in host device RAM and writes the reconstructed block into host device ROM.

摘要： Systems and methods are provided for reorganizing static file system (SFS) images for efficient differencing, updating and to reduce the update time. The systems and methods are for updating compressed read-only memory file system (CRAMFS) format images as an example. The reorganizing receives an image that includes one or more SFS components such as CRAMFS components and determines any changed sections within the SFS images. Reorganized CRAMFS components are generated using information of the CRAMFS components by moving any of the changed sections from a first position to a second position in the component. The second position can follow all unchanged data sections of the image. A modified image is generated that includes the reorganized CRAMFS component. The modified image is used in SFS differencing and updating.

摘要： Systems and methods for CRAMFS file system differencing and updating are provided that include portion-level differencing and block-level updating of blocks of an original image. The differencing and updating split CRAMFS images into portions using CRAMFS file system structure information and block information and perform dependency analysis using hint/list files from the CRAMFS split module. A delta file is generated for each portion (portion-level differencing) of the new CRAMFS image; the delta file includes information of differences between the portion of the new CRAMFS image and the portion of the original CRAMFS image to which the new CRAMFS image portion corresponds. The delta files are transferred to a device where the device target CRAMFS image is updated block-by-block using information of the delta files. The update reconstructs all portions of the new CRAMFS image in a block in host device RAM and writes the reconstructed block into host device ROM.
