[参考译文] TMS320F28388D：有关链接器命令文件中存储器映射说明的问题。

https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/1170711/tms320f28388d-question-about-memory-map-description-in-linker-command-file

您好！  

我对存储器映射描述有一些疑问。

MCU 有两个存储器映射：程序和数据。  

C2000 Academy 建议存储器说明必须如下单独描述每个存储器。  

但是 、C2000WARE 提供的链接器命令文件没有说明。

对于新器件(C2000第3代器件)、是否不需要此说明  

下面的内存说明为 F2838x_flash_cla_lnk_cpu1.cmd
