Problems solved by technology

At present, when GM upgrades the firmware, it needs to use the U disk and SD card that store the upgrade data to upgrade the firmware, or even disassemble the upgraded device, and use the slow and unstable JTAG emulation mode to upgrade the firmware. And the traditional firmware uses a single firmware mode, and each firmware update needs to re-write the overall DSP firmware
Once the programming fails due to accidents such as power failure during the programming process, it will not be self-recoverable and can only be repaired by emulator programming.
It can be seen that traditional maintenance methods increase equipment maintenance costs

Embodiment Construction

[0016] 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.

[0017] Such as figure 1 , a method for efficient and reliable ADI-DSP firmware startup, upgrade and restoration, including LDR firmware area, is characterized in that, said LDR firmware area includes Bootloader firmware, Backup firmware and APP firmware; wherein said Bootloader firmware is used for configuration The system is basically initialized and the boot firmware is selected. The Bootloader firmware starts the APP firmware first, and then starts the Backup firmware when the APP firmware cannot be started normally.

[0018] Such as figure 2 As shown, the Bootloader firmware normally starts the APP firmware. This mode is the normal boot and startup process of this product, which can imple...

Abstract

The invention discloses a method for efficiently and reliably starting, upgrading and restoring ADI-DSP firmware. The ADI-DSP firmware comprises an LDR firmware area, and is characterized in that the LDR firmware area comprises Bootloader firmware, Backup firmware and APP firmware; the Bootloader firmware is used for basically initializing a configuration system and choosing boot firmware, the Bootloader firmware firstly starts the APP firmware, and when the APP firmware cannot be normally started, the Backup firmware is started. The method for efficiently and reliably starting, upgrading and restoring the ADI-DSP firmware has the advantages that 1, traditional single firmware is divided into three parts of firmware, when firmware upgrade is conducted in occasions of normal business upgrade, BUG repair and the like, only the APP firmware needs to be renewed; 2, USB upgrade can be achieved in the APP firmware, and thus the upgrade speed is increased, and the burn steps are simplified; 3, an onboard is used for backup of the firmware, and thus it guaranteed that the equipment can never lose the firmware.

Description

technical field [0001] The invention relates to an efficient and reliable method for starting, upgrading and restoring ADI-DSP firmware. Background technique [0002] At present, with the popularity of ADI-DSP processors in China, the logic that the processor itself can handle in equipment development is limited and does not have functional scalability. New functions need to be upgraded to solve the problem. At present, when GM upgrades the firmware, it needs to use the U disk and SD card that store the upgrade data to upgrade the firmware, or even disassemble the upgraded device, and use the slow and unstable JTAG emulation mode to upgrade the firmware. And the traditional firmware uses a single firmware mode, and each firmware update needs to re-write the overall DSP firmware. Once the programming fails due to accidents such as power failure during the programming process, it will not be self-recoverable and can only be repaired by emulator programming. It can be seen t...
