Cy_Crypto_Server_Start()

cy_en_crypto_status_t Cy_Crypto_Server_Start	(	cy_stc_crypto_config_t const *	config,
		cy_stc_crypto_server_context_t *	context
	)

This function starts the Full functionality for the Crypto server on the server side core, sets up an interrupt for the IPC Crypto channel, sets up an interrupt to catch Crypto HW errors.

This function available for Server side only.

Note

The Crypto server can be run as singleton (not multi-instance) application on the one of available cores at the same time.

Parameters

config	The Crypto configuration structure.
context	The pointer to the cy_stc_crypto_server_context_t structure that stores the Crypto server context.

Returns

cy_en_crypto_status_t

Function Usage

    /* Scenario: Configure Server and Client as follows:
     * Server:
     *  - IPC channel for communication: 9
     *  - IPC interrupt structure used for new request notifications: 1
     *  - Data request handler: default
     *  - Hardware errors handler: default
     * Client:
     *  - IPC channel for communication: 9
     *  - IPC interrupt structure used for data ready notifications: 2
     *  - Data Complete callback: not used

Cy_Crypto_Server_Stop()

cy_en_crypto_status_t Cy_Crypto_Server_Stop

(

void

)
