Method for improving debugging speed during process of system development

Abstract

The invention provides a method for improving a debugging speed during the process of system development, which solves the technical problem to meet file system debugging so as to further accelerate the research and development speed with simple operation. The adopted technical scheme is as follows: adding a development board module circuit with a random storage unit in a debugging system, and compiling the program codes of a file system by virtue of a computer; storing the compiled files into kernel image and generating image files; downloading the image file into the random storage unit of a development board system kernel by virtue of a network interface and a matched transfer protocol; and electrifying a development board, and then further correcting or finishing debugging by judging the correctness of the program codes of the file system. Since the generated kernel images integrate the file system, the invention improves the download speed, saves the time for programming flash and is more helpful for a developer to concentrate on modifying codes, thus shortening the developing time.

Description

technical field [0001] The invention relates to a method for improving the debugging speed of a research and development system during the development stage, in particular a method for downloading a file system to a random storage unit ram of a development board by using a simple file transfer protocol tftp to debug the file system. Background technique [0002] In recent years, the linux operating system has been widely used in network communication, consumer electronics, manufacturing, security systems, industrial control, military, etc. field. [0003] Nowadays, the functions of application software are constantly enriched, hardware supports network connection, low power consumption, low cost, and fierce market competition all require us to develop products that meet market demand in a timely manner to seize the market. How to quickly and easily download and debug the kernel and file system in new product development is the key to software development. [0004] However,...

Problems solved by technology

[0016] In order to solve the technical problem of providing simple operation and satisfying file system debugging at the same time so as to further speed up the research and development speed of the development stage, the present invention designs a method for improving the file system debugging speed, and downloads the pre-debugged program code by means of a network transmission protocol Go to the development board for power-on and running test. When the operation is unsuccessful, re-modify the program code to avoid repeated flash programming and shorten the development time
