Embodiment Construction

[0033] After the embedded device 10 is turned on, it generally selectively enters two modes, namely the system startup mode and the system recovery mode. The startup of these two modes requires the first operation of the corresponding loading boot program. In addition, the system startup mode and the system recovery mode The operation of the system also requires the operation of the system file and the system backup file. In the following description, the bootloader programs corresponding to the two startup modes of the embedded device 10 are the same bootloader program, and the system backup file and the system file are also the same.

[0034] figure 1 Shown is a functional block diagram of an embodiment of the embedded device 10 of the present invention. The embedded device 10 includes a call module 100 , a detection module 102 , a control module 106 , a memory 110 and a processor 112 . In this embodiment, the memory 110 includes a flash memory 1101 and a random access mem...

Abstract

The invention provides embedded equipment which comprises a boot load program and an internal memory and can be in a system starting mode and a system restoring mode. The embedded equipment comprises a calling module, a detection module and a control module, the calling module is used for calling the boot load program, the detection module detects whether a flag bit of the internal memory is a first preset value or not, and the control module is used for utilizing the boot load program to enter the system starting mode when the flag bit of the internal memory is not the first preset value and utilizing the boot load program to enter the system restoring mode when the flag bit of the internal memory is the first preset value. The invention further provides a starting method of the embedded equipment. By the method, the embedded equipment can enter the two modes through the boot load program.

Description

technical field [0001] The invention relates to embedded technology, in particular to an embedded device and a starting method thereof. Background technique [0002] In embedded systems, there is usually no firmware program like the Basic Input Output System (BIOS) in a personal computer, but the boot loader (boot loader) is used to initialize the Central Processing Unit (CPU). ) and related input and output devices, and call system files. In addition, when the system needs to be restored, the embedded device needs another boot loader to initialize the device and call the system backup file to enter the system recovery mode. Therefore, embedded devices generally have two similar bootloaders, but one is used for normal startup of the system and the other is used for system recovery. Therefore, the current startup of embedded devices is not only because two bootloaders are required And increasing the cost and time of compiling the program will also increase the possibility o...
