Qoriq Trust Architecture 2.1 User Guide Jun 2026

If the hashes do not match, the boot sequence halts immediately. Phase 3: Image Verification

Ensuring the system only boots unaltered, authorized code.

This guide is current as of TA 2.1 implemented in LS series chips. Always verify your exact SoC version, as fuse maps differ slightly between T-series (e500 cores) and Layerscape (ARM Cortex-A). qoriq trust architecture 2.1 user guide

The Qoriq Trust Architecture 2.1 is likely an updated version of the earlier 2.0 release. Some key features of this architecture might include:

Since the is not public, you must follow these steps to obtain it: If the hashes do not match, the boot

: Hardware that monitors the system state and manages transitions between secure and non-secure modes.

: Use of the Security Fuse Processor (SFP) to store permanent system secrets, such as the Intent to Secure (ITS) bit and the Super Root Key Hash (SRKH) . Always verify your exact SoC version, as fuse

The foundational public key. Up to four SRK hashes can be burned into the OTP fuses, allowing key revocation if a key is compromised.

// Using /dev/crypto or keyctl #include <asm/crypto.h> struct caam_snvs_key key; key.slot = 0; memcpy(key.data, user_key, 16); ioctl(fd, CAAM_SNVS_ADD, &key);

Validates the next stage bootloader (e.g., U-Boot) before execution. 2. Secure Fuse Processor (SFP) Role: Stores permanent, non-volatile configuration data.
