Transitioning from a development state to a "Secure" state involves several critical hardware and software steps.
Losing the private key used for signing means no further updates can be deployed to secured devices. 📈 Best Practices for Developers
Use the PAMU (Peripheral Access Management Unit) to restrict peripheral access to specific memory regions. qoriq trust architecture 21 user guide
Always offload TLS/SSL tasks to the SEC engine to save CPU cycles.
💡 Always utilize the CST (Code Signing Tool) provided by NXP to automate the creation of your Command Sequence Control (CSC) structures. Transitioning from a development state to a "Secure"
Test the boot sequence in "Check" mode before blowing the ITS (Intent to Secure) fuse. ⚠️ Common Challenges
The immutable starting point for security. Always offload TLS/SSL tasks to the SEC engine
Offloads cryptographic tasks like AES, RSA, and SHA.
Use the NXP Code Signing Tool (CST) to generate headers.
