Please, where can I find a "key_pair_generation" example code for the Discovery Kit B-L4S5_IOT01A? (STSAFE)

[CMura.2]

I tried porting the example code has been done for the Nucleo board to the B-L4S5_IOT01A but I get STSAFEA_COMMUNICATION_ERROR as result. SEE BELOW

Key pair generation demonstration:

 

 1. Generate key pair through STSAFE-A's private key slot 1

 

 => Use StSafeA_GenerateKeyPair API

 

 StatusCode = STSAFEA_INVALID_PARAMETER 48.

 

 /* Check null pointers */

 

 IS_STSAFEA_HANDLER_VALID_PTR(pStSafeA) 1.

 

 IS_STSAFEA_CONDITIONAL_LVBUFFER_VALID_PTR(pOutPubX) 1.

 

 IS_STSAFEA_CONDITIONAL_LVBUFFER_VALID_PTR(pOutPubY) 1.

 

 pOutPointReprensentationId 48.

 

 /* Check parameters */

 

 **Inside StSafeA_TransmitCommand **

 

 StatusCode StSafeA_TransmitCommand 0.

 

 **Inside StSafeA_Transmit **

 

 StatusCode StSafeA_Transmit 0.

 

 **Inside StSafeA_TransmitCommand **

 

 StatusCode StSafeA_TransmitCommand 0.

 

 **Inside StSafeA_Transmit **

 

 StatusCode StSafeA_Transmit 0.

 

 /* Transmit */

 

 StatusCode = STSAFEA_INVALID_PARAMETER 0.

 

 /* after StSafeA_ReceiveResponse */

 

 StatusCode StSafeA_ReceiveResponse 1.

 

 StatusCode StSafeA_GenerateKeyPair 1.

 

 2. Signature verification result (0 means success): 1

 

**key_pair_generation(&stsafea_handle) != 0 **

 

STSAFEA_COMMUNICATION_ERROR
