void	back_trace (uint32_t fp)

void	exc_info_display (const exc_info_t *exc)
	Print exception info.

void	wait_apps_prepare_for_rebooting (void)
	Wait for the apps to finish the preparing for rebooting. eg. notify the apps and finish coredump if the debug is enable; Wait for the apps refresh the flash.

void	do_hard_fault_handler (exc_context_t *exc_buf_addr)
	Prototype for the assembly language hard-fault handler. This will setup the stack and attempt to generate a stack trace to aid debug.
