I am currently using a BF534 in my prototype, and now the security issue came up. Do I have to change processor to protect my FW from being copied or do I have any other possibilities ?
Lockbox is only the security future available on Blackfin processor such as ADSP-BF54x, ADSP-BF52x, and ADSP-BF51x.
The ADSP-BF70x Blackfin+® and ADSP-SC58x/ADSP-2158x SHARC+® processors feature a security solution for protecting IP and data. A secure operation environment is also provided for code execution, and an entire system infrastructure is available, composed of a number of functional blocks, including cryptographic hardware accelerators, a system protection unit (SPU), a system memory protection unit (SMPU), a one-time programmable memory (OTP), secure debug, and secure booting.
For more information please refer to application note EE-366, Secure Booting Guide for Blackfin+® and SHARC+® Processors
