Embodiment Construction
[0057] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0058] Such as figure 1 Shown, the upgrading method of the application program of embedded system of the present invention comprises:
[0059] Step 11, obtaining a lossless service reset request, said reset request carrying a lossless service upgrade mode flag information of an application program to be upgraded;
[0060] Step 12, according to the upgrade mode flag information, save the data information in the reset process of the embedded system to the designated area of the DRAM, and generate a reset command;
[0061] Step 13, reset the embedded system according to the reset instruction;
[0062]Step 14, after the embedded system is reset, extract and restore the data information from the designated area of the DRAM.
[0063] The above step 11 t...

The invention provides an upgrade method and an upgrade device for application programs of an embedded system. The upgrade method comprises: obtaining a lossless business reset request, the reset request carrying lossless business upgrade method sign information of a to-be-upgraded application program; according to the upgrade method sign information, storing data information in a reset process of the embedded system into a designated region of a dynamic random access memory, to generate a reset instruction; according to the reset instruction, resetting the embedded system; after the embedded system is reset, extracting and recovering the data information from the designated region of the dynamic random access memory. The scheme makes external business chip data not be damaged in an upgrade process of the embedded system, so as to improve system reliability. Since the external business chip data is stored in the dynamic random access memory of the system in a reset process, cost is reduced, access time of the system is reduced, and efficiency is improved.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for upgrading an application program of an embedded system. Background technique [0002] At present, many embedded devices in the communication field, especially long-running high-reliability systems and equipment, have strict requirements on the reliability and stability of hardware systems and software systems. For example, the PTN (Packet Transport Network, Packet Transport Network) equipment running on the core network requires stable services and long online running time. During the operation of the equipment, if hardware design defects are found, they need to be avoided by upgrading the system, or the software itself needs to be upgraded. It is best to upgrade the system version without affecting the normal service forwarding function of the current embedded device. The system upgrade steps under normal circumstances include: [0003] 1...
