可以用SECTION的方式来定义。

strongchen

先在PRM文件中加入你要的SECTION地址：

/* This is a linker parameter file for the GP32 */
NAMES END /* CodeWarrior will pass all the needed files to the linker by command line. But here you may add your own files too. */

SEGMENTS /* here all RAM/ROM areas of the device are listed. Used in PLACEMENT below. */
  Z_RAM  = READ_WRITE 0x0040 TO 0x00FF;
  RAM    = READ_WRITE 0x0100 TO 0x023F;
  ROM    = READ_ONLY  0x8000 TO 0xFDFF;
  T_ROM  = READ_ONLY  0xFC06 TO 0xFDFF;
END

PLACEMENT /* here all predefined and user segments are placed into the SEGMENTS defined above. */
  DEFAULT_ROM                   INTO ROM;
  DEFAULT_RAM                   INTO RAM;
  _DATA_ZEROPAGE, MY_ZEROPAGE   INTO Z_RAM;
  MY_ROM                        INTO T_ROM;
END

STACKSIZE 0x50

VECTOR 0 _Startup /* reset vector: this is the default entry point for a C/C++ application. */
//VECTOR 0 Entry  /* reset vector: this is the default entry point for a Assembly application. */
//INIT Entry      /* for assembly applications: that this is as well the initialization entry point */

然后在程序中将次函数定义为放在MY_ROM：

#pragma CODE_SECTION MY_ROM

void funct1(void){
  asm lda #2;
}

#pragma CODE_SECTION DEFAULT

void main(void) {
funct1();
}
