It safely traps and reports exceptions caused by program errors in VxWorks tasks, and it reports occurrences of interrupts that are explicitly connected to other handlers. For information about architecture-dependent exception handling facilities, see the manual entry for excArchLib. The VxWorks kernel and other system tasks continue uninterrupted. It may be possible to fix the task and resume execution with tr. However, tasks aborted in this way are often unsalvageable and can be deleted with td. When an interrupt that is not connected to a handler occurs, the default handler provided by the architecture-specific module displays a description of the interrupt on standard output.
VxWorks and RTLinux RTOS
These commands can be entered at the command line via a console, modem or telnet session. All non-numeric argument values are taken as strings and hence, must be enclosed in double quotes. For example, suppose command foo takes two arguments, arg1 and arg2, where arg1 is a character string and arg2 is a hexadecimal numeric value. This command would be entered as follows:.
This exercise is an introduction refresher to basic VxWorks program development. You will also experiment with WindView and see how to use it to measure the performance of the system. Call the project Simple. You can use your workspace for a previous course.
