CORESIGHT_TRACE_FRAME_SIZE

#define CORESIGHT_TRACE_FRAME_SIZE   (CORESIGHT_TRACE_FRAME_SIZE32 * sizeof(uint32_t))

#include <zephyr/debug/coresight/cs_trace_defmt.h>

Size of trace deformatter frame size in bytes.

CORESIGHT_TRACE_FRAME_SIZE32

#define CORESIGHT_TRACE_FRAME_SIZE32   4

#include <zephyr/debug/coresight/cs_trace_defmt.h>

Size of trace deformatter frame size in 32 bit words.

Typedef Documentation

cs_trace_defmt_cb

typedef void(* cs_trace_defmt_cb) (uint32_t id, const uint8_t *data, size_t len)

#include <zephyr/debug/coresight/cs_trace_defmt.h>

Callback signature.

Parameters

id	Stream ID.
data	Data.
len	Data length.

Function Documentation

cs_trace_defmt_init()

int cs_trace_defmt_init

(

cs_trace_defmt_cb

cb

)

#include <zephyr/debug/coresight/cs_trace_defmt.h>

Initialize Coresight Trace Deformatter.

Parameters

cb

Callback.

cs_trace_defmt_process()

int cs_trace_defmt_process	(	const uint8_t *	data,
		size_t	len
	)

#include <zephyr/debug/coresight/cs_trace_defmt.h>

Decode data from the stream.

Trace formatter puts data in the 16 byte long blocks.

Callback is called with decoded data.

Parameters

data	Data.
len	Data length. Must equal 16.

Return values

0	On successful deformatting.
-EINVAL	If wrong length is provided.
