TA 2.1 uses a 256-bit SRK hash. The guide provides explicit warnings:

The NXP QorIQ Trust Architecture represents a comprehensive hardware-implemented security framework designed to protect embedded systems from a wide array of threats. Embedded within Layerscape and QorIQ processors—such as the T-series (e.g., T1040, T2080) and early LS-series SOCs—Trust Architecture 2.1 (often coupled with the SEC 5.0 crypto-accelerator) provides the cryptographic foundation needed to establish a verifiable root of trust.

If you are currently configuring a specific NXP system processor, let me know: To ensure that security doesn't degrade system performance,

The first stage is the immutable code inside the chip's ROM. The BootROM validates the first external bootloader image (e.g., Pre-Boot Loader or PBL) using a digital signature..

Leaving the JTAG interface open allows attackers to attach hardware debuggers and read out memory contents or hijack code execution. Trust Architecture 2.1 supports challenge-response secure debug authentication. Hardware debugging can be permanently disabled via fuses, or configured to require a signed cryptographic token to unlock access on a per-device basis. Tamper Detection and Key Erasure
