An online upgrade method, dsp controller and upgrade system

Abstract

An embodiment of the invention discloses an online upgrading method. The method comprises the steps of running a bootstrap program of a bootstrap address area in a DSP controller; running an application of an application address area in the DSP controller to initialize the DSP controller and copy an upgrading task program to an RAM of the DSP controller, wherein the upgrading task program is set in the application, and the application address area is located in a FLASH storage area; running the application to judge whether an online upgrading flag exists in an auxiliary chip or not, and displaying the online upgrading flag after the auxiliary chip receives an online upgrading command of an upper computer; if it is judged that the online upgrading identifier exists in the auxiliary chip, jumping to the RAM of the DSP controller to execute the upgrading task program; and running the upgrading task program to control the DSP controller to obtain an upgrading program through the auxiliary chip and write the upgrading program in the application address area. Embodiments of the invention furthermore disclose the DSP controller and the upgrading system. According to the upgrading method, the DSP controller and the upgrading system, the upgrading operation can be simplified and the storage resources can be saved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an online upgrading method, a DSP controller and an upgrading system. Background technique [0002] Usually, DSP software upgrade requires a boot project and an application project, and the DSP software upgrade is realized by means of an emulator or a serial port, but both the emulator or the serial port upgrade method have the problems of cumbersome operation and low security . Moreover, a solidified boot project has been burned into many DSP chips. When upgrading the DSP software, it is necessary to adopt the traditional upgrade method according to the solidified boot project, resulting in inflexible upgrades and limited scope of use. Although it has been used in DSP In the method of establishing a new boot project, after the DSP is powered on, the solidified boot project is first executed, and then the new boot project is guided to be executed and upgraded according to ...

[0002] Usually, DSP software upgrade requires a boot project and an application project, and the DSP software upgrade is realized by means of an emulator or a serial port, but both the emulator or the serial port upgrade method have the problems of cumbersome operation and low security

Moreover, a solidified boot project has been burned into many DSP chips. When upgrading the DSP software, it is necessary to adopt the traditional upgrade method according to the solidified boot project, resulting in inflexible upgrades and limited scope of use. Although it has been used in DSP In the method of establishing a new boot project, after the DSP is powered on, the solidified boot project is first executed, and then the new boot project is guided to be executed and upgraded according to the set upgrade method, but currently the new boot project is stored in an independent The storage space is like a separate FLASH sector, and the general boot project is relatively small, occupying a sector is easy to cause waste of resources, and for large applications, it is easy to cause insufficient storage resources
