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 fatal_error_occurred directive when there is no user handler |
---|
27 | configured or the user handler returns control to RTEMS. The |
---|
28 | default fatal error handler disables processor interrupts to |
---|
29 | level 7, places the error code in D0, and executes a stop |
---|
30 | instruction to simulate a halt processor instruction. |
