Assuming that the BSP part has been completed, the following describes how to develop an application.ProgramBasic steps:1. first, we can establish a new project in tornado. We can see that there are two types of images available: bootable and downloadable. in the initial stage of development, we usually first set up a bootable project that does not contain the application layer module, compile a VxWorks image that contains the basic components and sta

It's Friday night again, no overtime tomorrow, it's a beautiful day. Now look at the third main function usrinit () VxWorks started.
This function is the first function that executes in RAM, mainly clears the BSS segment, sets the exception vector, and then calls Syshwinit () to initialize the hardware. What is a
In the face of the ever-expanding network, with the combination of multiple protocols, I don't know if you know anything about the VxWorks network protocol stack. With the rapid growth of the Internet and the prevalence of WWW, TCP/IP has become the preferred network protocol for intranets and wide area networks. As more applications require protocol capabilities, IETF organizations are working to add new features to TCP/IP. Now WindRiver has released
VxWorks has three types of images:
There are three file types for VxWorks Image
Loadable images: boot-Rom guides you through the network port or serial port to download to ram
ROM-based images (compression/no compression): this means that the image is directly burned into the Rom, and the image is then run into RAM during the runtime.

VxWorks has three images:VxWorks image has three types of files
Loadable Images: Downloaded to ram by Boot-rom via the network port or serial port
rom-based Images (compressed/uncompressed): The image is burned directly into the ROM, executed when the image is copied into RAM.
The instruction portion of the Rom-resident images:image resides in ROM execution. Only part of the data segment is copied into RAM.

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
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 ).

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.

The System symbol table contains the names and addresses of all global symbols. It will be used in the following 4 functions:
