Create the first VxWorks bootable image Project--socket communication Experiment Daniellee_ustb 2013.6.25 qq:382899443 Sleep late yesterday, a bit sleepy in the morning, but the creation of the first VxWorks Bootableimage in today finally run successfully. The morning's sleepy mind swept away, small excited to talk about the process. Many problems have been encountered and collated for reference. Click Cr

During this period, the socket connection cannot be detected and exited due to network disconnection or long connection time. Technical Background: the target machine runs on vxworks, while the pc can connect to the target board through serial port and telnet. After the pc connects to vxworks through telnet, execute the shell program we have written, here we call this shell program CLI. Because the telne

the target file: 0. Add the global symbol to the system symbol table; 1. Add the global and local symbols to the system symbol table;-1, the symbol is not added to the system symbol table. Select 1 to facilitate the use of the symbols in shell. The noabort parameter indicates whether errors during loading can be ignored. If the value is true, the errors are ignored. If the value is false, the errors are not ignored. Name indicates the file name to be loaded, including the file path. Note: LD is

1 taskdelayTaskdelay () provides a simple task sleep mechanism, which is also commonly used in applications that require a timing/latency mechanism. The format is status taskdelay (INT ticks/* Number of ticks to delay task */), We can see that the unit for implementing latency using this function is tick (generally, one tick in the system is MS-level ). In VxWorks, The taskdelay () function can be used as follows: taskdelay (sysclkrateget () * 1 ). Th

A depressing week, a depressing week! Fuck the VxWorks! Fuck the workbench! Finally, I have commented out several lines of errors.CodeLater, compilation was successful, regardless of November 21, but this step has taken a lot of detours.Record it to be effective! Will these compilation errors be solved next week, or will they not be solved? 1. The licence in the same directory is not used when workbench 3.2 is installed. The installation is unsu

VxWorks interprocess communication 2--signal Volume one. The concept of signal volumeis the main mechanism to realize the mutual exclusion and synchronous operation of tasks. The VxWorks provides a highly optimized semaphore that is the fastest in all communication mechanisms between tasks.Two The classification of Signal volumeBinary semaphores(binary): The best way to complete mutual exclusion, synchronou

The VxWorks symbol table, also known as the kernel symbol table (kernel), stores functions, variables, and constant information for each module in the program (also includes variables created by the shell). The symbol table consists of two types, the system symbol table and the user symbol table. system Symbol Table: The System symbol table contains the names and addresses of all global symbols. It will be used in the following 4 functions: 1. Kernel

Ensure that config_commands includes pai_pai_elf.Add # define config_assist_elf to the configs (board_name). H of the Board.Re-compile. Now the bootvx command is available.Prepare the VxWorks image. I like the bin format, XXX-objcopy-O binary VxWorks. Bin.VxWorks must be loaded to the address set in config. H, for example, 0x100000. If you download it over the network: TFTP 100000

Service Interruption Program It is an important part of the device driver. In order to respond to external interruptions in a timely manner and prevent interruption loss, the interrupted service program should be as small as possible, and only the most necessary tasks should be placed Run the command in the interrupted service program. Generally, after the system is started and the hardware device is initialized, the ISR and the interrupt vector are mounted: the interrupt vector can be mounted

printf ()-Write a formatted string to the standard output stream (ANSI).Logmsg () does not actually perform the output directly to the logging streams, but instead queues the message to the Logg ing task, logmsg () can be called from interrupt service routines.printf () is the output of information to a standard output device (stdin/stdout), which can block if the device is working at this time.Logmsg () is a way of using Message Queuing, which sends an information address to a queue that is pri

On the one hand, the Vxworks application can be integrated with the kernel for debugging. On the other hand, the application and the kernel can be separated for debugging. When the application is correct, it can be integrated into the kernel. The second debugging method is described in detail below, which is the most convenient. Using this method, you do not need to write the application every time, and then compile and download the application to the

I have done Web cgi programs on vswitches in the past. It was done on the 51 system. I remember that the Principles are similar. I made the pages into binary arrays, But now I forgot, I had to get familiar with it again. The following are from http://ajonbin.spaces.live.com/blog/cns! 5619a73390dcd51e! 132. Entry. If you have any copyright issues, please let me know. Goahead, VxWorks, and CGI are the most closely-monitored clients in
