Enumeration Type Documentation

anonymous enum

#include <rpmb.h>

RPMB I/O type.

Enumerator
RPMB_TYPE_BLOCK	block I/O
RPMB_TYPE_BYTE	byte I/O

Function Documentation

TEE_Result TEES_RPMBCheckEnable

(

void

)

#include <rpmb.h>

Check RPMB availability.

Return values

TEE_SUCCESS	in case of success
error	code in case of errors TEE_ERROR_NOT_IMPLEMENTED - not implemented on current device TEE_ERROR_NOT_SUPPORTED - RPMB Key is not programmed (RPMB is disabled) other implementation-defined error codes are possible

TEE_Result TEES_RPMBRead	(	uint32_t	partition,
		uint32_t	offset,
		uint8_t *	data,
		uint32_t	size,
		uint8_t	type
	)

#include <rpmb.h>

Read data from RPMB Storage.

Parameters

[in]	partition	Partition number of RPMB storage
[in]	offset	Offset value of data. The start address is 0 in each partition
[out]	data	Buffer for data which read from RPMB
[in]	size	Size of data to be read from RPMB
[in]	type	rpmb data size type (block or byte)

Return values

TEE_SUCCESS	in case of success
error	code in case of errors

TEE_Result TEES_RPMBWrite	(	uint32_t	partition,
		uint32_t	offset,
		const uint8_t *	data,
		uint32_t	size,
		uint8_t	type
	)

#include <rpmb.h>

Write data to RPMB Storage.

Parameters

[in]	partition	Partition number of RPMB storage.
[in]	offset	Offset value of data. The start address is 0 in each partition
[in]	data	Buffer for data which write to RPMB
[in]	size	Size of data to be write to RPMB
[in]	type	rpmb data size type (block or byte)

Return values

TEE_SUCCESS	in case of success
error	code in case of errors
