11 | @section Introduction |
---|
12 | |
---|
13 | Upon detection of a fatal error by either the |
---|
14 | application or RTEMS the fatal error manager is invoked. The |
---|
15 | fatal error manager will invoke the user-supplied fatal error |
---|
16 | handlers. If no user-supplied handlers are configured, the |
---|
17 | RTEMS provided default fatal error handler is invoked. If the |
---|
18 | user-supplied fatal error handlers return to the executive the |
---|
19 | default fatal error handler is then invoked. This chapter |
---|
20 | describes the precise operations of the default fatal error |
---|
21 | handler. |
---|
22 | |
---|
23 | @section Default Fatal Error Handler Operations |
---|
24 | |
---|
25 | The default fatal error handler which is invoked by |
---|
26 | the @code{rtems_fatal_error_occurred} directive when there is |
---|
27 | no user handler configured or the user handler returns control to |
---|
28 | RTEMS. The default fatal error handler performs the |
---|
29 | following actions: |
---|
30 | |
---|
31 | @itemize @bullet |
---|
32 | @item disables processor interrupts, |
---|
33 | @item places the error code in @b{r0}, and |
---|
34 | @item executes an infinite loop (@code{while(0);} to |
---|
35 | simulate a halt processor instruction. |
---|
36 | @end itemize |
