MSP430G2553在.cmd文件中的Flash起始位置（origin）和长度（length）

Chuan Wang

Other Parts Discussed in Thread: MSP430G2553

我用CCS8（ Version: 8.2.0.00007 ）编译、连接项目时，生成的“lnk_msp430g2553.cmd”文档的“Memory”里，flash只给分配了约2KB的内存，而查找技术手册显示有16KB的闪存。。。这个内部地址能不能自己改啊，现在连除法和乘法都算不出来。

就比如里面FLASH的origin能不能往前调一下，然后length调长一点，2KB太小了。

可以修改的，您可以看一下

www.ti.com.cn/.../slau144j.pdf

的 1.4.1 Flash/ROM

The start address of Flash/ROM depends on the amount of Flash/ROM present and varies by device. The end address for Flash/ROM is 0x0FFFF for devices with less that 60KB of Flash/ROM.

另外附上G2553的内存表格
