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. @ifinfo @node Default Fatal Error Processing Default Fatal Error Handler Operations, Board Support Packages, Default Fatal Error Processing Introduction, Default Fatal Error Processing @end ifinfo @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 to level 7, places the error code in D0, and executes a stop instruction to simulate a halt processor instruction.
