Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0033] Such as Figures 1 to 3 As shown, a WIFI-based DSP and ARM dual-core controller online upgrade system, including a server, a wireless router and several devices. The device includes ARM, DSP and WIFI modules. The device establishes a wireless connection with the wireless router through the WIFI module, the wireless router establishes a communication link with the server, and the ARM connects with the DSP through the SPI bus. ARM's internal FLASH has four areas A, B, C, and D. Area A is used to store the BootLoader of ARM, areas B and C are used to store user programs, and area D is used to store related parameters. DSP includes internal FLASH, internal RAM and external SRAM. After the ...

Abstract

The invention discloses a dual-core controller online upgrading system of DSP and ARM based on WIFI and a method thereof. The system comprises servers, wireless routers and several devices; the deviceincludes ARM, DSP and a WIFI module. The device establishes wireless connection with a wireless router through the WIFI module, the wireless router and the server establish communication link, and ARM connects with DSP through an SPI bus. The internal FLASH of ARM has four regions: A, B, C and D. The A region is used to store the BootLoader of ARM, the B region and the C region are used to storethe user program, the D region is used to store the related parameters. DSP includes internal FLASH, internal RAM, and external SRAM. The invention has the following beneficial effects: 1, the invention can upgrade the DSP and the ARM of the controller at the same time; 2, the peripheral circuit of the upgrade system in the invention is simple, and the remote upgrade can be realized without complex circuit; 3, the software of the host compute in the invention supports upgrade DSP or ARM program separately; 4, the upper computer software of the invention supports the simultaneous batch online upgrade program.

Description

technical field [0001] The invention specifically relates to a WIFI-based DSP and ARM dual-core controller online upgrading system and method thereof. Background technique [0002] According to research, it is impossible for any software developer to perfect software development. After a period of use of software, due to various reasons, there will always be various problems. With the emergence of new technologies and the continuous increase of user requirements, software Upgrades are becoming more and more important. Now basically all kinds of software in China have the function of automatic upgrade or online upgrade. Generally, when there is a new version, the user is prompted to confirm the upgrade, start to download the software, install the software after the download is completed, and automatically delete the upgrade package after the installation is completed. However, this method has some disadvantages. For example, the original program cannot be used during the upg...
