Fields

header: TlvHeader

Header identifying this struct.

config_version: u32

Configuraion version (monotonically increasing per owner).

sram_exec: SramExecMode

Whether the owner wants to permit code execution in SRAM.

ownership_key_alg: OwnershipKeyAlg

The key algorithm of the ownership keys.

update_mode: OwnershipUpdateMode

Ownership update mode.

min_security_version_bl0: MinSecurityVersion

Set the minimum security version to this value.

lock_constraint: u32

The device ID locking constraint.

device_id: [u32; 8]

The device ID to which this config applies.

reserved: [u32; 16]

owner_key: KeyMaterial

The owner identity key.

activate_key: KeyMaterial

The owner activation key.

unlock_key: KeyMaterial

The owner unlock key.

data: Vec<OwnerConfigItem>

A list of other configuration items (application keys, flash configuration, etc).

signature: EcdsaRawSignature

A signature over this block with the owner key.

seal: Vec<u8>

A sealing value that locks a configuration to a particular device.
