MDK M0程序编译问题请教

新手上路学习M0

安装了MDK。
新建工程包含helloworld.c 和 Startup/ARM下面的startup_CMSDK_CM0.s 和system_CMSDK.c
选择的ARM Cortex-M0核
helloworld.c很简单：
#include <stdio.h>

int main (void) {
  printf ("Hello World!\n");
  return 0;
}

编译后出现：
Error：L6221E, Execution region ER_RO with Execution range [0x00000000, 0x000003c0) overlaps with Execution region ER_RW with Execution range [0x00000000, 0x00000018)
Error：L6221E, Execution region ER_RO with Execution range [0x00000000, 0x000003c0) overlaps with Execution region ER_ZI with Execution range [0x00000018, 0x00000278)

请问这个怎么处理哦？
