arch_stk_trace()

void arch_stk_trace

(

int

n

)

Do a stack trace from the current function.

This function does a stack trace from the current function, printing the results to stdout. This is used, for instance, when an assertion fails in assert().

Parameters

n	The number of frames to leave off. Each frame is a jump to subroutine or branch to subroutine. assert() leaves off 2 frames, for reference.

arch_stk_trace_at()

void arch_stk_trace_at	(	uint32	fp,
		int	n
	)

Do a stack trace from the current function.

This function does a stack trace from the the specified frame pointer, printing the results to stdout. This could be used for doing something like stack tracing a main thread from inside an IRQ handler.

Parameters

fp	The frame pointer to start from.
n	The number of frames to leave off.
