#include "stm32f10x.h"

#define ABC 0x08012000

#pragma arm section rodata="abc"

const unsigned short abc[] = {
0x1001,
0x1002,
0x1003,
0x1004
0x1005
};

如何把abc[]首地址指向地址0x08012000？
KEIL中要设置吗？

Use #pragma arm section [section_type_list] to place functions and variables in separate named sections. You can then use the scatter-loading description file to locate these at a particular address in memory. 不过这个方法有点复杂。

还有个简单的方法如下：
const unsigned short abc[] __attribute__((at(0x08012000))) = {
      0x1001,
      0x1002,
      0x1003,
      0x1004,
      0x1005
};
