Embodiment

[0046] Examples, see Figure 1-2 , the present invention provides a technical solution: a system firmware update method design for an embedded system, including the U-boot source code contained in the embedded system and a command tool based on bootloader and integrating other commands, the command tool can automatically Complete a series of hardware-related operation commands. The operation command is to separate the operation purpose from the platform hardware-related operation command. The command tool can automatically execute a series of related commands according to the input parameters required by the operator against the command tool. The U-boot source code is based on the hardware The platform is configured with device information, so that you don’t need to pay attention to hardware information when using this command tool to operate. The functions that the command tool can implement include: updating system firmware to FLASH, formatting FLASH device partitions, viewin...

Abstract

The invention discloses a system firmware updating mode design of an embedded system, which comprises a U-boot source code contained in the embedded system and a bootloader-based command tool integrated with other commands, and the command tool can automatically complete a series of hardware-related operation commands. The operation difficulty of system firmware updating can be effectively reduced, and an operator does not need to memorize a large number of operation instructions and parameter usage methods thereof. Meanwhile, compatibility of different hardware platforms is fully considered, and operation process changes caused by changes of the hardware platforms are avoided. According to the scheme, the development efficiency can be effectively improved, and developers are helped to complete system firmware updating operation better and faster.

Description

technical field [0001] The invention relates to the technical field of system firmware update, in particular to a system firmware update mode design for an embedded system. Background technique [0002] At present, many embedded processors use the bootloader to complete the work of board startup and kernel loading. Therefore, when updating the system firmware (bootloader image, kernel image, and file system image) in practical applications, the bootloader console command line automatically There command is an essential command tool. [0003] The bootloader of the embedded system must undertake the work of updating the firmware of the embedded system. The system firmware update work mainly includes: bootloader programming, kernel programming, file system programming, startup parameter setting, environment variable setting, network parameter setting, etc. [0004] The bootloader itself integrates a wealth of system firmware update command tools, which can perform operations ...
