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
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？
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。

在程序中你是如何写的？
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
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？

这肯定是不可行的。超过部分将无法储存。

FLASH是带有CRC功能的。该错误的意思就是无法为“DataBuff”生成CRC代码。
可能还是FLASHE的大小不够。
