MSP430FR4133 FRAM 擦除保护 [复制链接]

芯片 MSP430FR4133 ，软件IAR FOR MSP430 V6.30.3 ，环境 WINDOWS XP

烧写器 FET430UIF。

希望 在FRAM 0xC400其始地址中保存一段数据，数据量比较大约2k，保存用户数据，information FRAM空间太小。

不希望在IAR烧写的时候擦除这段空间。参考IAR帮助文件，提到：

Example
--erase_exclude 0xC400-0xD400

To set this option, use Project>Options>Debugger>Extra Options.

使用时出错 ：

请问有什么方法可以确保更新程序时，这段不被擦除？谢谢、
