CN112328253A - Multi-file automatic generation and combination method based on single-chip microcomputer compiler - Google Patents

Abstract

The invention relates to a multi-file automatic generation and combination method based on a singlechip compiler, which is characterized in that an executable tool is written by a python language, and the executable tool is HexPad.exe: the Hex file is 256 bytes filled; hex binconvert. exe: the Hex and Bin files are converted with each other; createhexfromxml. exe: converting the data in the xml file into a Hex file; combinehex.exe: merging the needed Hex files; the invention automatically generates the files after compiling, shortens the time for burning and upgrading the files, avoids manual errors, can uniformly manage executable tools, meets the requirements of different chips and is convenient to transplant and popularize.

Description

Multi-file automatic generation and combination method based on single-chip microcomputer compiler

Technical Field

The invention relates to the field of single-chip microcomputers, in particular to a multi-file automatic generation and combination method based on a single-chip microcomputer compiler.

Background

With the widespread use of the single chip microcomputer system, the Flash memory system of the single chip microcomputer is generally divided into 3 parts: bootloader, Application, and DFlash, where Bootloader and Application compiler are usually compiled into two separate files, and DFlash needs to be written in a specific way, but 3 parts need to be burned in during mass production chip burning, which is complicated in steps.

At present, a plurality of open-source tools can combine the parts 3 manually to burn in a unified way, and the manual operation steps are multiple and are easy to make mistakes.

Disclosure of Invention

The invention aims to provide a multi-file automatic generation and combination method based on a single-chip microcomputer compiler aiming at the technical problems.

The technical scheme for solving the technical problems is as follows:

the multi-file automatic generation and combination method based on the singlechip compiler comprises the following steps:

step 1, filling a BMCU _ Application _ Pad.hex file compiled by a compiler into a BMCU _ Application _ Pad.hex file with the width of 256 bytes, converting data in a Dataflash.xml file into a Dataflash.hex file, combining the BMCU _ Bootloader.hex file, the BMCU _ Application _ Pad.hex file and the Dataflash.hex file into a BMCU _ Application _ ALL.hex file and storing the BMCU _ Application _ ALL.hex file, wherein the BMCU _ Application _ ALL.hex file is a burning file;

and 2, converting the BMCU _ Application _ pad.hex file into a BMCU _ Application _ pad.bin file, wherein the BMCU _ Application _ pad.bin file is an upgrading file.

The invention has the beneficial effects that: the automatic generation after compiling shortens the time of burning and upgrading file production, avoids manual mistakes, can implement unified management of tools, meets the requirements of different chips, and is convenient to transplant and popularize.

Detailed Description

The principles and features of this invention are described below in conjunction with examples which are set forth to illustrate, but are not to be construed to limit the scope of the invention.

As shown in fig. 1, the multi-file automatic generation and merging method based on the single-chip microcomputer compiler includes the following steps:

step 1, filling a BMCU _ Application _ Pad.hex file compiled by a compiler into a BMCU _ Application _ Pad.hex file with the width of 256 bytes, converting data in a Dataflash.xml file into a Dataflash.hex file, combining the BMCU _ Bootloader.hex file, the BMCU _ Application _ Pad.hex file and the Dataflash.hex file into a BMCU _ Application _ ALL.hex file and storing the BMCU _ Application _ ALL.hex file, wherein the BMCU _ Application _ ALL.hex file is a burning file;

and 2, converting the BMCU _ Application _ pad.hex file into a BMCU _ Application _ pad.bin file, wherein the BMCU _ Application _ pad.bin file is an upgrading file.

In this embodiment, the executable tool is written in the python language

Hex. exe: 256 byte stuffing of Hex file

Hex binconvert. exe: hex and Bin file interconversion

Createhexfromxml. exe: converting data in xml file into Hex file

Combinehex.exe: merging required Hex files

Adding corresponding executable file execution method after link linking in compiler, correspondingly converting required 3 parts and combining into burning and upgrading file required by single chip microcomputer chip

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.

Claims (1)

1. The multi-file automatic generation and combination method based on the singlechip compiler is characterized by comprising the following steps of:

step 1, filling a BMCU _ Application _ Pad.hex file compiled by a compiler into a BMCU _ Application _ Pad.hex file with the width of 256 bytes, converting data in a Dataflash.xml file into a Dataflash.hex file, combining the BMCU _ Bootloader.hex file, the BMCU _ Application _ Pad.hex file and the Dataflash.hex file into a BMCU _ Application _ ALL.hex file and storing the BMCU _ Application _ ALL.hex file, wherein the BMCU _ Application _ ALL.hex file is a burning file;

and 2, converting the BMCU _ Application _ pad.hex file into a BMCU _ Application _ pad.bin file, wherein the BMCU _ Application _ pad.bin file is an upgrading file.
