Abstract

The invention relates to the technical field of Bootrom, and discloses a Bootrom online updating and debugging system, which comprises the following steps: S1, compiling Bootrom; s2, carrying out debugging, wherein a file name needs to be modified to be bootrom.z; s3, carrying out programming, and after programming is completed, carrying out direct restarting, and not needing power-off; and S4, performing running: after the Bootrom is started, newly adding two commands: z--debugging Bootrom, and u--updating Bootrom. According to the system, under the Bootrom menu, updating can be directly carried out, the protocol supports ftp and tftp, implementation is more flexible, operation is more convenient, when the updated Bootrom does not reach expectation or breaks down, the Bootrom can be returned to the normal version through power-off restart, and the development efficiency of the Bootrom is greatly improved.

Description

technical field [0001] The invention relates to the technical field of Bootrom, in particular to a Bootrom online updating and debugging system. Background technique [0002] As the requirements for localization are getting higher and higher, the information processing platform built with the independently controllable Hua Rui No. 2 chip will be the trend of future development. Hua Rui No. 2 chip has multiple startup methods, such as lpc, pcie, and srio. The modules adopt different designs to meet product requirements, and the startup methods will also change with the design. Bootrom is a bootloader, which will be modified accordingly due to different module designs. Bootrom involves all low-level codes. Once an error occurs, the module will not start normally. You can only switch to the programming mode through pin configuration, and complete the update through the serial port. Not only is the speed slow, but the efficiency is also low. [0003] There are two ways to upda...
