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. + -- cgit v1.2.3
