Function Documentation

aducm3029_trng_fill_buffer()

int aducm3029_trng_fill_buffer	(	struct no_os_trng_desc *	desc,
		uint8_t *	buff,
		uint32_t	len
	)

Fill buffer with random numbers.

Parameters

desc	- TRNG descriptor
buff	- Buffer to be filled
len	- Size of the buffer

Returns

0 if no errors, -1 is an error occurs and the data in the buffer is not useful.

aducm3029_trng_init()

int aducm3029_trng_init	(	struct no_os_trng_desc **	desc,
		struct no_os_trng_init_param *	param
	)

Initialize descriptor.

Parameters

desc	- Where to store the TRNG Descriptor
param	- Unused

Returns

0 or -1 if desc is null

aducm3029_trng_remove()

int aducm3029_trng_remove

(

struct no_os_trng_desc *

desc

)

Free resources allocated in descriptor.

Parameters

desc	- TRNG Descriptor
