我创建了一个内存链接器脚本并将其保存为eclipse中的memory.ld:项目:属性:gcc链接器:杂项:我添加了-M -T memory.ld

memory.ld:

    MEMORY
{
        ram (rw)   : ORIGIN = 0x4000000 ,  LENGTH = 2M  
}

SECTIONS
{
  RAM : { *(.myvarloc) 

} > ram }

在我的c程序中:我做了一个全局声明:

__attribute__ ((section(".myvarloc")))

 uint8 measurements [30];

错误:

/usr/bin/ld: FEBRUARY section `.text' will not fit in region `ram'
