大家好,用 MSP430FR5738做了个板子,但是手册中 BSL加密的一节实在是看不明白
Writing 05555h to BSL
Signature1or BSL Signature2 disables the BSL function and any access to the BSL memory space
causes a vacant memory access as described in Section1.9. Most BSL commands require the BSL to be
unlocked by a user-defined password.An incorrect password erases the device memory as a security
feature. Writing 0AAAAh to BSL Signature1or BSLSignature2 disables this security feature. This causes
a password error to be returned by the BSL,but the device memory is not erased.In this case,unlimited
password attempts are possible.
有几个问题请教,翻了一遍文档也找不到明确答案,如果大家有更详细文档希望能共享
1 写0x5555h到签名1或2可以完全关闭BSL功能?
2 怎么实现需要密码的访问BSL?密码存储在那些位置呢?
3怎么样实现密码错误就删除存储数据,information 段会删除吗?
4 不删存储的又怎么实现呢?
望大家赐教!
