SES编译出错`.rti_fn.1.end' will not fit in region ‘UNPLACED_SECTIONS’

最近在`segger embedded studio for arm v4.16`移植rtthread v3.1.3编译提示问题如下：
```
Output/Debug/Exe/template.elf section `.rti_fn.1.end' will not fit in region `UNPLACED_SECTIONS'
region `UNPLACED_SECTIONS' overflowed by 8 bytes
```

尝试修改flash_placement.xml文件如下：
```

编译通过，但是finsh组件未被初始化，不能运行
查看编译后的map文件

```

现在没有头绪，希望各位大神能赐教！
