SPECIAL CODE-BASED METHOD FOR BATCH UPGRADING MULTI-FIRMWARE DISTRIBUTED BOARD CARD

摘要

A special code-based method for batch upgrading a multi-firmware distributed board card. The method comprises: the positions of N pieces of firmware on a device end distributed board card that require upgrading are determined, and various firmware release version bin packages and various pieces of firmware release version differentiated content are acquired; N firmware release version bin packages are combined to form one release version bin package that appears as a binary file, and N pieces of firmware release version differentiated content are embedded into the binary file of the release version bin package; the binary file of the release version bin package is encoded by using an encryption algorithm so as to form an encrypted bin package; and in an upgrade process, a device end receives the encrypted bin package, parses the release version binary file in the encrypted bin package by using a symmetric decryption algorithm, and acquires the N pieces of firmware differentiated content on the distributed board card; and a differential adaptation upgrade of each distributed board card firmware is performed according to the N pieces of firmware differentiated content and N firmware types. The attached figure is figure 2.
