Function Documentation

§ TRNG_s_handlePsaMsg()

psa_status_t TRNG_s_handlePsaMsg ( psa_msg_t * msg )

Handles PSA messages for TRNG secure driver.

Note: This function should be called by secure partition thread only.

Parameters

[in] msg pointer to PSA message

Return values

PSA_SUCCESS	if successful.
PSA_ERROR_PROGRAMMER_ERROR	if any args point to secure addresses.

§ TRNG_s_init()

void TRNG_s_init ( void )

Initializes the TRNG secure driver.

Note: This function should be called by the non-secure client and power to TRNG HW must be enabled first.

§ TRNGCC26XX_s_setSamplesPerCycle()

int_fast16_t TRNGCC26XX_s_setSamplesPerCycle	(	TRNG_Handle	handle,
		uint32_t	samplesPerCycle
	)

Fast veneer to set the number of entropy generation cycles before the results are returned.
