ROM prints a status code (via GPIOs) indicating 0xE05C (Signature Failure). Cause: You programmed the fuses with srkhash.bin , but your image was signed with a different private key. Solution: Verify the hash using the display_fuses utility. Regenerate the signature using the exact SRK table that matches the fuses. Which specific (e
The CPU initializes in a default, secure state and points to the IBR.
The IBR locates the boot images on the storage medium (such as SPI Nor, eMMC, or SD). Appended to these images is a Command Sequence File (CSF). The CSF contains the cryptographic signatures, public keys, and commands required to validate the code blocks. Phase 3: Public Key Verification Regenerate the signature using the exact SRK table
Secure engines used for fast authentication (e.g., RSA, ECDSA). Detailed Features in QTA 2.1 1. Enhanced Secure Boot & Image Validation
Sign the binary using the CST tool to append the Command Sequence File (CSF) headers: ./cst --input input_file_config --output u-boot-signed.bin Use code with caution. Phase 3: Programming the Fuses (Blowing Fuses)
