Example Embodiment

[0017] The core idea of ​​the present invention is to write a universal startup program for different hardware single boards supporting the same CPU scheme, and run the universal startup program when the system is started to perform corresponding processing according to the current hardware single board.

[0018] Such as figure 1 As shown, the general startup method of the embedded device in this embodiment includes the following steps:

[0019] 101. Add an EGIS (protected partition) to the NVRAM (non-volatile random access memory) of the device circuit board to store bootType (device startup type) and HwVersion (hardware identification code) parameter information. In this step, EGIS can also be set in other storage media.

[0020] 102. Write a universal startup program and solidify it into the flash storage unit of the circuit board; the universal startup program is a basic startup code generated according to the environmental parameters of different hardware single boards belongin...

Abstract

The invention discloses a method for generally starting embedded equipment. The method supports various hardware single boards which adopt the same CPU schemes and comprises the following steps of: adding a protection partition used for storing starting types and hardware identification codes of the equipment; writing a general starting program, and solidifying the general starting program in a flash storage unit, wherein the general starting program comprises same starting codes and different starting codes, the same starting codes support each hardware single board, and the different starting codes correspond to different equipment starting types and the hardware identification codes; configuring corresponding equipment starting types and the hardware identification codes according to the current hardware single boards, and storing the corresponding equipment starting types and the hardware identification codes into the protection partition when the equipment is electrified; and resetting a system, starting the equipment from the flash storage unit, and configuring the hardware single boards according to the different equipment starting types and the hardware identification codes. The method saves development time and development cost, reduces error rates of the development and compiling of software, and has the advantages of simple operation and convenient maintenance.

Description

[technical field] [0001] The invention relates to the field of embedded technology, in particular to a general startup method for embedded devices to support multiple different hardware single boards using the same CPU solution. [Background technique] [0002] In recent years, with the continuous deepening of informatization in various industries, embedded systems have been widely used in network communications, consumer electronics, manufacturing, industrial control, security systems and other fields due to their customizability. At the same time, the market competition is becoming more and more fierce, and the MCU and peripheral hardware in the embedded system are updated rapidly. Developers must produce products that meet market demand in a timely manner to seize the market. The cornerstone of new product development is to have an efficient and easy-to-modify, maintain, and debug hardware platform. [0003] Due to the increase of products, there will be more and more ha...
