Partition Secret Buffered WR Lockable RD Lockable Description
CREATOR_SW_CFG no no yes (Digest) yes (CSR) Software configuration partition for device-specific calibration data (Clock, LDO, RNG, device identity).
OWNER_SW_CFG no no yes (Digest) yes (CSR) Software configuration partition for data that changes software behavior, specifically in the ROM. E.g., enabling defensive features in ROM or selecting failure modes if verification fails.
HW_CFG no yes yes (Digest) no EN_SRAM_IFETCH: TODO: add EN_CSRNG_SW_APP_READ: This input efuse is used to enable access to the NIST internal state per instance. EN_ENTROPY_SRC_FW_READ: This input efuse is used to enable access to the ENTROPY_DATA register directly. EN_ENTROPY_SRC_FW_OVER: This input efuse is used to enable access to the firmware override FIFO and other related functions.
SECRET0 yes yes yes (Digest) yes (Digest) Test unlock tokens.
SECRET1 yes yes yes (Digest) yes (Digest) SRAM and FLASH scrambling key roots used for scrambling key derivation.
SECRET2 yes yes yes (Digest) yes (Digest) RMA unlock token and creator root key.
LIFE_CYCLE no yes no no Life-cycle related bits. This partition cannot be locked as the life cycle state needs to be able to advance to RMA in-field. Note that while this partition is not marked secret (i.e. it is not scrambled) it is not readable nor writeable via the DAI. Only the LC controller can access this partition, and even via the LC controller it is not possible to read the raw manufacturing life cycle state in encoded form, since that encoding is considered a netlist secret. The LC controller only exposes a decoded version of this state.
