@chapter Default Fatal Error Processing
|
|
|
|
@section Introduction
|
|
|
|
Upon detection of a fatal error by either the
|
|
application or RTEMS the fatal error manager is invoked. The
|
|
fatal error manager will invoke the user-supplied fatal error
|
|
handlers. If no user-supplied handlers are configured, the
|
|
RTEMS provided default fatal error handler is invoked. If the
|
|
user-supplied fatal error handlers return to the executive the
|
|
default fatal error handler is then invoked. This chapter
|
|
describes the precise operations of the default fatal error
|
|
handler.

|
@section Default Fatal Error Handler Operations
|
|
|
|
The default fatal error handler which is invoked by
|
|
the @code{rtems_fatal_error_occurred} directive when there is
|
|
no user handler configured or the user handler returns control to
|
|
RTEMS. The default fatal error handler disables processor interrupts,
|
|
places the error code in @b{XXX}, and executes a @code{XXX}
|
|
instruction to simulate a halt processor instruction.
