Deprecated Functions#

SE_initPubkey#

SE_Response_t SE_initPubkey (uint32_t key_type, void * pubkey, uint32_t numBytes, bool signature)

Init pubkey or pubkey signature.

Initialize public key stored in the SE, or its corresponding signature. The command can be used to write:

• SE_KEY_TYPE_BOOT – public key used to perform secure boot

• SE_KEY_TYPE_AUTH – public key used to perform secure debug

Note

• These keys can not be overwritten, so this command can only be issued once per key per part.

Returns

• One of the SE_RESPONSE return codes.

SE_initOTP#

SE_Response_t SE_initOTP (SE_OTPInit_t * otp_init)

Initialize SE one-time-programmable (OTP) configuration.

Configuration is performed by setting the desired options in the SE_OTPInit_t structure.

This function can be used to enable secure boot, to configure flash page locking, and to enable anti-rollback protection when using the SE to perform an application upgrade, typically a Gecko bootloader upgrade.

Before secure boot can be enabled, the public key used for secure boot verification must be uploaded using SE_initPubkey().

Warnings

• This command can only be executed once per device! When the configuration has been programmed it is not possible to update any of the fields.

Returns

• One of the SE_RESPONSE return codes.
