Function Documentation

hal_rng_status_t HAL_RngInit

(

void

)

Note

This API should be called at the beginning of the application using the random adapter driver.

Return values

kStatus_HAL_RngSuccess

Rand module initialize succeed

void HAL_RngDeinit

(

void

)

Note

This API should be called when not using the rand adapter driver anymore.

hal_rng_status_t HAL_RngHwGetData	(	void *	pRandomNo,
		uint32_t	dataSize
	)

Note

This API should be called to get random data.

Parameters

pRandomNo	Pointer to random data
dataSize	The random data size

Return values

kStatus_HAL_RngSuccess

Rand get data succeed

hal_rng_status_t HAL_RngGetData	(	void *	pRandomNo,
		uint32_t	dataSize
	)

Note

This API should be called to get random data.

Parameters

pRandomNo	Pointer to random data
dataSize	The random data size

Return values

kStatus_HAL_RngSuccess

Rand get data succeed

hal_rng_status_t HAL_RngSetSeed

(

uint32_t

seed

)

Note

This API should be called to set seed before get random data.

Parameters

seed	Seed of the random hardware generator

Return values

kStatus_HAL_RngSuccess	Rand set rand seed succeed
KStatus_HAL_RngNotSupport	Rand set rand seed not support
