TMS320F28377D-EP: CCS编译错误

将一段数组分配到flash段中后出现如此错误，请问是什么原因，如何解决 谢谢

Ben Qin：

你好，

Aaron zhou 说：将一段数组分配到flash段中后出现如此错误

你是如何操作的？

,

Aaron zhou：

TIDsp我是新手， 我看手册RAMGS是4KB一个block， 代码中定义的Databuff段超过了这个数，编译提示无法放入指定分区，然后我将Databuff指定存放于FLASHE块，就出现主楼的错误。cmd文件配置如下。

Ben Qin：

在程序中你是如何写的？

,

Aaron zhou：

程序中就是用pragma定义了几个结构体放进Databuff段，你能告诉我这个错误提示具体是什么意思吗， 为什么和crc有关

,

Aaron zhou：

假如我定义的某个变量，比如一个数组，长度超过了ram或者flash的块，可行吗？
