Embodiment Construction

[0020] The method for transplanting a general-purpose boot loader on a specific hardware platform, the method is realized on the BCM5358U hardware platform of Broadcom Corporation in the United States, and the transplantation process includes the following steps:

[0021] A. Convert the assembly code of the first part of the BCM5358U boot loader and the assembly code for CPU initialization in the second part according to the requirements of the general boot program, keep the original program structure, set the parameters of the file reading method, and convert the above code Write to the start of the first section in the generic bootloader,

[0022] B. Convert the device driver in the BCM5358U bootloader according to the requirements of the universal bootloader, and write the converted code into the second part of the universal bootloader,

[0023] C. Prepare the kernel startup parameters,

[0024] D. Compile the program, generate the target file, and write the target file in...

Abstract

The invention discloses a method for transplanting a universal boot loader on a specific hardware platform, belongs to a technology for processing system software, and in particular relates to a software transplant method for a cross-hardware platform. The method is implemented on a Broadcom (BCM) 5358U hardware platform of the Broadcom Corporation and comprises the following steps of: A, converting a BCM5358U boot loader according to a requirement of the universal boot loader, setting parameters of a file reading mode, and writing codes into a starting part in the universal boot loader; B, converting a device driver in the BCM5358U boot loader according to the requirement of the universal boot loader, and writing the converted codes into a second part of the universal boot loader; C, preparing kernel starting parameters; and D, compiling a program, generating a target file, and writing the target file into a BCM5358U program storage area. By adoption of the method, the problem about running of the universal boot loader on a BCM chip platform can be solved, and the system software which is booted based on the universal boot loader can be conveniently and quickly transplanted to the BCM5358U platform.

Description

technical field [0001] The invention belongs to the processing technology of system software, and in particular relates to a software transplantation method across hardware platforms. Background technique [0002] Any processor needs a bootloader when it is turned on and running. It mainly completes the driver loading of the system hardware, sets up the stack, calls the operating system kernel and loads other system software. A typical example is the familiar BIOS (Basic Input Output System). [0003] The BCM5358U launched by Broadcom, the global leader in the wired and wireless communication semiconductor market, is a new Intensi-fi XLR wireless local area network (WLAN) VoIP router single-chip system platform solution, which has 3G support and industry-leading Enhanced features such as performance and optimal power consumption. Therefore, the chip is an ideal choice when developing devices such as 3G USB modems. [0004] CFE is the abbreviation of Common Firmware Environ...
