METHOD FOR INSTALLING PATCH FILE

摘要

A computer-implemented method for installing patch files to a local storage of an embedded electronic device includes the following steps. A file header is read and an original checksum value is received from the file header. Patch files from a data package are written to a data area of the local storage. A checksum value of the patch files written in the data area is calculated. The checksum value with the original checksum value is compared to determine integrality of the patch files.
