vxworks commands

VxWorks uses a variety of basic data structures, such as two-way linked lists, queues, and trees. This article will introduce the implementation of these basic data structures in VxWorks. 1. Two-way linked list Two-way linked list is the simplest data structure, and its implementation is also very simple. In addition, two-way linked list is often the basis for implementing other data structures, so this art

During application programming, a task usually needs to execute a specified action after a specific delay, such as waiting for peripherals to ensure data reliability, control speaker voice time and serial communication timeout and resend. This requires the timer mechanism to measure a specific length of time. As a real-time embedded system, VxWorks provides various timing interface functions. The following describes some common timing methods based on

VxWorks startup code romstart () function analysis Daniellee_ustb QQ: 382899443 I haven't learned VxWorks for several days, so I really feel a bit regretful. Every time you stop your dream runway for various reasons, the road to work is full of embarrassment. Fortunately, the serial server and the completion of key verification have come to an end for the moment and continue to study hard. Today, I went to

VxWorks startup code Romstart () function Analysis Daniellee_ustb 2013-6-14 qq:382899443 For several days did not learn vxworks, really a little remorse. Often for a variety of reasons to stop the dream runway, the road to work is really full of fetters. Fortunately, the serial server and the completion of critical verification, temporarily, continue to concentrate on learning. Today go to a multiplexer co

, then taskdelay (1) at moment B is exactly a tick cycle. It can be seen that a latency of 10 ms is required to call taskdelay (2. Taskdelay has an error similar to one tick. taskdelay (n) is actually a latency (n-1) Tick ~ The time of N tick. The delay precision is L/N, and the 1 s delay is the error limit of taskdelay (60) is 1.6%, while the error limit of taskdelay (1) is 100%. When using taskdelay, you must note that even after N tick tasks, delayed tasks cannot be called and the execution s

Wind River, a wholly owned subsidiary of Intel, recently announced the immediate launch of Wind River Tilcon Graphics Suite 5.7. This is a software development solution for embedded applications. It can efficiently build and deploy multi-platform and highly available graphical user interfaces. Wind River Tilcon Graphics Suite 5.7 is the result of the company's acquisition of Tilcon in February this year and product integration, further expanding the Wind River software development product lineup

to start entering the OpenGL world under VxWorks and learn the basic concepts of OpenGL.To really develop applications, you must use DRI, which is out of the scope of this article.2. PreparationsMy development environment isTornado 2.2.VX 3, 5.5Windml 3.0Mesa 4.0 (download later) 3. Compile the Mesa for windml 3D graphics libraryDownload Mesa 4.0 and decompress it to C:/tornado 2.2/target/src.Directory structure In tornado, create a downloadable proj

Usrinit () function analysis of VxWorks startup code Daniellee_ustb QQ: 382899443 It's another Friday evening, so you don't have to work overtime tomorrow. It's a wonderful day. Now let's look at the third major function usrinit () started by VxWorks (). This function is the first function executed in Ram. It clears BSS segments, sets exception vectors, and CALLS syshwinit () to initialize hardware. What i

Assuming the BSP section is ready, let's say the basic steps of developing the application:1. Starting with a new project from Tornado, you can see that there are two types of images to choose from: Bootable and downloadable, which usually start with a bootable project that does not contain the application-tier module. Compile a vxworks image containing the basic components to start the system; In fact, this step compiles a

VxWorks uses Intconnect () to hook up the interrupt service program, but for PCI devices, the Pciintconnect () hook interrupt is generally used, and the main difference between it and Intconnect () is that the interrupt vector used by Intconnect () is exclusive, Pciintconnect () allows multiple external interrupts to share an interrupt vector. It internally uses a list to manage multiple ISR, when an interrupt occurs, each ISR on a linked list is call

There are three types of binary semaphores, counting semaphores, and mutexes in the wind core, and the POSIX (Portable Operating system interface) Semaphore is also available in order to make the application portable. In VxWorks, the signal volume is the main means to achieve the task synchronization, but also the best choice to solve the task synchronization.About mutex implementations:It is easy to implement mutual exclusion using binary semaphores,

the bad blocks are randomly distributed. I have tried to eliminate bad blocks before, but I found that the yield rate is too low and the cost is too high. So far, no effective methods have been completely eliminated.The NAND device needs to initialize the media to detect Bad blocks and mark them as unavailable. In an existing device, a high failure rate may occur if this processing is not performed in a reliable way.II,Existing methods supported by VxWorks
