. Among them, the files in the A11 folder are common to most BSP, and generally do not need to be modified, especially "Configall". h "; The files in the integrator920t folder are the BSP files to be written, which are often closely related to the system hardware.3.2.1 Modifying MakeflieThe makefile file defines the rules for compiling and linking the entire BSP, such as the selection of the compilation tool, the compilation options and the Include file path, and the control of the type of the g

The main content of this video tutorial:This article introduces the development of embedded systems based on VxWorks, and strives for further development on the basis of comprehensive development. This topic will introduce various aspects of VxWorks development, including: VxWorks kernel environment, kernel mode development, user mode RTP development, driver deve

This article is taken from the network and the source is unknown. 1. Difference Between bootrom and boot image, and the connection and difference between Boot Image and VxWorks ImageBootrom refers to on-chip bootrom, which is embedded with a small bootProgram(Bootloader), similar to the BIOS storage area on the PC motherboard. It is not the same as boot image. The bootrom area in the VxWorks document re

, which provides related functions for symbol table operations. System symbol table allows the same name conflict, the same name symbol back to join the symbol table without error, when referencing the symbol, the system uses Symfindbyname to find the default, so the most recently added symbols are always found first, instead of the old symbol to complete the reference. The presence of a symbol with the same name also poses another problem, and cannot ensure that the found symbol is loaded by it

system symbol table allows conflict of the same name. If a symbol of the same name is added back to the symbol table, no error is reported. When a symbol is referenced, the system uses symfindbyname by default. Therefore, the newly added symbol is always found first, replace the old symbol to complete the reference. The existence of symbols with the same name poses another problem. You cannot ensure that the searched symbols are loaded by yourself, that is, the group number cannot be guaranteed

Introduction to embedded real-time operating system VxWorks Author: Song Baohua Source: Tianji Development Embedded real-time operating system (VxWorks)-Development Environment Construction The VxWorks Operating System is an embedded real-time operating system (RTOs) designed and developed by WinDriver in 1983 ), it is widely used in fields with extremely high re

compiler fills it so that the next instruction is on an address that is divisible by 16. Snapping allows the CPU to take commands a little faster._rominit:The following is the first instruction of the VxWorks system. At this point the CPU is still in real mode, the program can only access 1 m of memory space, the default instruction is 16-bit code. The CPU needs to be switched to protected mode as soon as

1. VxWorks Loading1.1 load from the tffs File SystemTornado trueffs is a m-systems Flite implementation method compatible with VxWorks. It provides a unified block device interface for a wide variety of flash storage devices, it also features reentrant and thread security and supports most popular CPU architectures. With tornado trueffs, applications read and write to flash storage devices as if they operat

scenario analysis, and in the first chapter of the book there is an introduction to the mixed programming of C language assembly in GCC, and the compiler used by VxWorks is gcc!You might as well try it out, so you have the following code: /*****************gettsc-get TSC count************************************* Get the TSC (timestamp counter) count value, put the counter high in Phi, low deposit pl

The VxWorks Operating System is an embedded real-time operating system (RTOs) designed and developed by WinDriver in 1983 ), it is widely used in fields with extremely high real-time requirements, such as communication, military, aviation, and aerospace, with its excellent reliability and excellent real-time performance, such as satellite communication, military drills, ballistic guidance, and aircraft navigation. On F-16, FA-18 fighter, B-2 stealth b

The latest Cisco has abandoned its proprietary iOS core, using Linux as the base platform for ASR1000 's control plane software. It is rumored that the software platforms of H3C and other manufacturers have also turned to Linux, which used to be based on VxWorks. A few years ago, even VxWorks's developer Wind River Company announced support for both VxWorks and Linux. In this view, Linux in the field of net

Making floppy disk boot diskThe boot disk means that it is bootrom to run a program on the machine without installing the system. This section will be implemented through the VMware Virtual machine simulation VxWorks hardware environment, through the virtual floppy disk emulation diskette to achieve the production of the boot disk.The meaning of BootromBootrom is the boot code for VxWorks operating system i

Hard real-time systems have a rigid, immutable deadlines that does not allow any errors that exceed deadlines. Soft real-time is a flexible and flexible, it can tolerate accidental time-out errors, the consequences of failure is not serious, for example, i

and the operating system to manage flash.Therefore, true flash is also used by many embedded operating systems, including the VxWorks of Fenhe Corporation. For this reason, the development of trueffs driver for Flash has become a must for embedded system developers. However, the development of the trueffs driver is closely related to the hardware, and the development process is also very difficult. However, there are a lot of related information abou
