@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 a user-supplied fatal error
|
|
handler. If no user-supplied handler is configured, the RTEMS
|
|
provided default fatal error handler is invoked. If the
|
|
user-supplied fatal error handler returns 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 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 (i.e.
|
|
sets the I bit in the PSW register to 0), places the error code
|
|
in r1, and executes a break instruction to simulate a halt
|
|
processor instruction.
