OMAPL138 型号尾缀



请问OMAPL138型号尾缀中含有E(即Basic Secure Boot Enabled),和不含E尾缀的芯片有什么不同么?

  • For security enabled devices,TI’s Basic Secure Boot allows users to protect proprietary intellectual
    property and prevents external entities from modifying user-developed algorithms. By starting from a
    hardware-based “root-of-trust”, the secure boot flow guarantees a known good starting point for code
    execution.

  • 后缀有E的表示该芯片型号支持secure boot启动,其原理是芯片内部的ROM CODE无后缀没有E的有区别,会在ROM CODE内加入加密的功能。
