Program to run the test under vxworks accidental 40 ms tasks blocking problems, and the problems are difficult to repetition, sometimes programs run dozens of hours not to come out, sometimes 80 ms tasks and 40 ms tasks are blocked, sometimes 10 ms, ms, 20 to 40 ms, 80 ms are abnormal, but each time the 40 ms will be abnormal,
Consult everybody a great god, and what may cause the task block?

The problem you describe is drunk, lead to task obstruction was caused by abnormal single task, such as a stack of crossing the line and so on, have to do is to check your task processing, 40 ms task if you not interrupt trigger, and print the printf should not appear problem, feeling you know problem without screening, dormancy and screen is what mean? Your failure is run x86?CodePudding user response:
