Abstract
The invention discloses a method for transplanting a VXWORKS operating system, which comprises the following implementation processes: a phase of selecting a BSP development kit, a phase of transplanting a bootstrap program, a phase of transplanting VXWORKS, and a phase of perfecting the VXWORKS; at the initial stage of the transplantation and the development, when a display device does not adopt a supported, adopting a signal lamp identification method to identify the running process of a VXWORKS system; and running the bootstrap program first before running the VXWORKS system, loading the VXWORKS operating system and then running the VXWORKS operating system by the bootstrap program. The method for transplanting the VXWORKS operating system is simple and practicable, deepens layer by layer, achieves the maximum result with little effort to the transplantation of the VXWORKS operating system based on PXA255 hardware; besides the VXWORKS operating system is transplanted to a machine based on a PXA255 processor, and the overall performance of the machine can be improved.
Description
Technical field
The present invention relates to a kind of method of operating system transplantation, specifically a kind of method of VXWORKS operating system transplantation.
Background technology
VXWORKS operating system is a kind of embedded real-time operating system (RTOS) that U.S. WindRiver company designed and developed in nineteen eighty-three, is the key components of embedded-development environment.Good sustained developing ability, high performance kernel and friendly user's development environment occupy one seat in the embedded real-time operating system field.In the high field of high-quality precision and sophisticated technology such as it is widely used in its good reliability and remarkable real-time and communicate by letter, military affairs, Aeronautics and Astronautics and real-time requirement, as satellite communication, military exercises, trajectory guidance, aircraft navigation etc.On F-16, FA-18 fighter plane, B-2 stealth bombers and the Patriot Missile of the U.S., even on the Mars probes that martian surface lands, also used VXWORKS in April, 1997.
Summary of the invention
Technical assignment of the present invention provides a kind of method of VXWORKS operating system transplantation.
Technical assignment of the present invention realizes that in the following manner implementation process comprises selects BSP kit stage, boot transplanting stage, VXWORKS transplanting stage, VXWORKS to improve the stage; At the initial stage of transplanting development, adopt the signal lamp identification method to identify VXWORKS system operational process when can not support display device; Boot operation earlier before the operation of VXWORKS system, boot program loads VXWORKS operating system makes it operation then.
Based on the PXA255 processor VXWORKS operating system is transplanted.
Select the BSP kit stage, select a BSP template with the similar VXWORKS of hardware.
Boot is transplanted the stage, selects serial ports as debug port, adds serial port drive and baud rate relevant configuration in the boot the inside, with the output redirection of system to serial ports; Before and after the program committed step, add the statement of signal lamp flicker, utilize the programming of JTAG instrument in BootLoad Flash after the boot compiling finishes; If boot operation is normal, and signal lamp shows that running to VXWORKS transplants the stage, and implementation process enters VXWORKS and transplants the stage; If it is undesired to move, reruns boot and transplant the stage.
Whether VXWORKS transplants the stage, at first generates the minimum core framework of VXWORKS, adds some necessary drivers, generates VXWORKS, and utilizes boot program loads to start to target machine, detect minimum core framework and move normally; If operation normally then enter VXWORKS and improve the stage; If it is undesired to move, reruns VXWORKS and transplant the stage.
VXWORKS improves the stage, adds other hardware driving, and whether detection is normal, revises the mode of boot program loads VXWORKS then, makes boot load VXWORKS from the storage medium of target machine; If it is undesired to move, reruns VXWORKS and improve the stage.
The method of a kind of VXWORKS operating system transplantation of the present invention, simple possible layer by layer deeply, plays a multiplier effect to the transplanting based on the VXWORKS operating system of PXA255 hardware; The VXWORKS operating system transplantation to the machine based on the PXA255 processor, can be improved the overall performance of machine.Thereby, have good value for applications.
Description of drawings
Accompanying drawing 1 is a kind of specific embodiments process flow diagram of method of VXWORKS operating system transplantation.
Embodiment
Embodiment:
Be elaborated in conjunction with the method for Figure of description based on the PXA255 processor below to a kind of VXWORKS operating system transplantation of invention.
The method of a kind of VXWORKS operating system transplantation of the present invention, based on the PXA255 processor VXWORKS operating system is transplanted, implementation process comprises selects BSP kit stage, boot transplanting stage, VXWORKS transplanting stage, VXWORKS to improve the stage; At the initial stage of transplanting development, adopt the signal lamp identification method to identify VXWORKS system operational process when can not support display device; Boot operation earlier before the operation of VXWORKS system, boot program loads VXWORKS operating system makes it operation then.
Select the BSP kit stage, select a BSP template with the similar VXWORKS of hardware.Present embodiment is selected the BSP kit based on the PXA250 processor, framework and peripheral hardware situation according to PXA255, basic configuration to hardware such as the frequency of the processor of making amendment based on the BSP kit of PXA250, storage space managements, remove the hardware driving of not supporting, the necessity of adding peripheral hardware drives.
Boot is transplanted the stage, selects serial ports as debug port, adds serial port drive and baud rate relevant configuration in the boot the inside, with the output redirection of system to serial ports; Before and after the program committed step, add the statement of signal lamp flicker, utilize the programming of JTAG instrument in BootLoad Flash after the boot compiling finishes.When target machine starts, can at first move this section program.
If boot operation is normal, and signal lamp shows that running to VXWORKS transplants the stage, illustrate that boot is transplanted to finish, and implementation process enters the VXWORKS transplanting stage; If it is undesired to move, reruns boot and transplant the stage.
Whether VXWORKS transplants the stage, at first generates the minimum core framework of VXWORKS, adds some necessary drivers, generates VXWORKS, and utilizes boot program loads to start to target machine, detect minimum core framework and move normally.If operation normally then enter VXWORKS and improve the stage; If it is undesired to move, reruns VXWORKS and transplant the stage.
VXWORKS improves the stage, adds other hardware driving, and whether detection is normal, if the mode of boot program loads VXWORKS is normally revised in operation then, makes boot load VXWORKS from the storage medium of target machine; If it is undesired to move, reruns VXWORKS and improve the stage.
