Embodiment 1

[0018] The embodiment of the present invention provides a kind of installation method of Vxworks operating system, and its implementation mode is as follows figure 1 As shown, including the following operations:

[0019] Step 1, customize the BSP (board support package, board-level support package) package according to the hardware resources of the target board;

[0020] As a high-real-time operating system, Vxworks is closely related to hardware. According to the different hardware resources of the target machine, unnecessary component configurations are deleted as appropriate, and system resources are allocated to each hardware reasonably, which can improve system performance and stability. sex. The system boot file compiled without the BSP package customized for the target machine often cannot run normally on the target machine. Therefore, the BSP package must be customized according to the hardware resources of the target machine at first.

[0021] Step 2, compiling the...

Embodiment 2

[0029] As a preferred embodiment, in the embodiment of the present invention, on the basis of embodiment 1, the specific implementation of step 3 may be:

[0030] Step 31, perform virtual disk operation in the BIOS ROM;

[0031] There are many ways to realize this step, and the most common way is to reserve a continuous storage space in the BIOS as a BIOS virtual disk; add an EVD (Embedded Virtual Disk, embedded virtual disk) module in the BIOS; During the self-test process, decompress the EVD module in the memory; update the number of disks, and update the entry address of the BIOS interrupt service routine; call the EVD module interrupt service routine to read and write to the BIOS virtual disk. In this way, the user can conveniently read and write data in the BIOS virtual disk just like accessing a disk. The operations on the virtual disk are generally carried out in the memory, which can improve the access and running speed of the system, so that the actual physical stora...

Embodiment 3

[0038] As a preferred embodiment, in the embodiment of the present invention, on the basis of Embodiment 1 and Embodiment 2, the specific implementation of step 4 may be:

[0039] 41. Restart the target board;

[0040] 42. Read the boot program of the boot sector of the primary partition of the virtual disk by the BIOS;

[0041] 43. Enter the system boot interface from the BIOS ROM under the guidance of the boot program to install the operating system.

Abstract

The invention is applicable to the technical field of computers and provides an installation method of a VxWorks operating system. The method includes: customizing a BSP (board support package) according to hardware resources of a target board; compiling the BSP to generate a system boot file; writing the system boot file into a BIOS ROM (basic input/output system read only memory); restarting the target board, and booting from the BIOS ROM to enter a system boot interface to install the operating system. System boot installation is booted in the BIOS ROM when the VxWorks operating system is installed by the method, an external memory of the target board need not be formatted, and accordingly the problem of conflict with disk formats in the installed operating system is avoided effectively. In addition, unnecessary occupation of external memory disk space is saved.

Description

technical field [0001] The invention belongs to the technical field of computers, in particular to a method for installing a Vxworks operating system. Background technique [0002] The Vxworks operating system is an embedded real-time operating system developed by Wind River Systems in 1983 and running on the target board. At present, during the installation process of the Vxworks operating system, the installation of the system boot file must be performed under the DosFS file system, occupying the main partition, and the size of the main partition is below 2G. Among them, the system boot file is the system file of Vxworks, usually named bootrom.sys or bootrom.bin, which is mainly used to complete the initialization and driving of the required equipment during the loading process, and then load the VxWorks kernel into the memory. DosFS is a file system compatible with MS-DOS (Microsoft Disk Operating System, Microsoft Disk Operating System). [0003] Some commonly used ope...
