Tornado2.2-vxworks5.5 test and debugging Guide

 

The integrated VxWorks Target Simulator-vxsim provides a debugging and simulation runtime environment consistent with the real target machine, allows developers to develop and debug without BSP, operating system configurations, and hardware devices of the target machine.

Vxsim indicates the significance of software developers. It is mainly because software development in embedded system development is usually restricted by the hardware development progress. Because software development must lag behind hardware development, vxsim solves this problem to a certain extent, affecting the product R & D progress. This allows users to leave the hardware environment unavailable in the initial stage of engineering development, tornado can be used to design hardware-independent modules.

The following is a simple PC simulation as the target machine for simple development and Debugging Processes, mainly to replace the text description in an image, may provide some help for the preliminary reporters.

1. Create a project

2. Create a bootable VxWorks Image

 

3. Select a BSP package

4. Generate a project

5. generated project directory

6. Compile a main. C program

#include <stdio.h> int WinMain(void){int nCount = 1234;printf("hello world!\n");printf("This is a demo program!\n");}

7. Add the main. C program (right-click the project)

8. Add the project after main. c

9. Modify usrappinit. C as follows:

/* usrAppInit.c - stub application initialization routine *//* Copyright 1984-1998 Wind River Systems, Inc. *//*modification history--------------------01a,02jun98,ms   written*//*DESCRIPTIONInitialize user application code.*/ /******************************************************************************** usrAppInit - initialize the users application*/ void usrAppInit (void)    {#ifdefUSER_APPL_INITUSER_APPL_INIT;/* for backwards compatibility */#endifWinMain();    /* add application specific code here */    }

10. Set the dependency (right-click the project)

11. compile all (right-click the project)

12. Enable vxsim lauch

13. Download the object file main. O, so that we can debug all the functions of Main. C.

14. Set a breakpoint of 6th rows in Main. C.

15. Run the program. The task starts with the winmain function.

16. After running the program, the program Pointer Points to the start point of the winmain function.

17. Let's take a look at the content in the watch window and vxsim interface at the program pointer operation.

A. Variable Window

B. vxsim content

18. Use the shell program

A. Shell help
