忘了说了
芯片是2401a，内部程序存储器是Flash
看一下你的.gel文件的设置！
高手能否给解释一下?
你用到.gel文件了吗，可也把你的.gel文件发来看看。
ccs自带的gel文件啊

你使用的片上存储器吧，片上存储器的0000h-2000h是flash,是不能load程序的，而且，你在.gel文件里设置成了禁止写 /* Program Memory Maps */
GEL_MapAdd(0x0000,0,0x2000,1,0); /* On-chip flash memory */
GEL_MapAdd(0x8000,0,0x0200,1,1); /* SARAM */
GEL_MapAdd(0xff00,0,0x0100,1,1); /* DARAM (B0), CNF=1 */
可你的MEMORY
{
PAGE 0:
VECS: origin=0000h, length=0040h
PVECS: origin=0044h, length=0100h
PM: origin=1000h, length=0200h
是从0000h始的，因此有此错误！
把memory改为
MEMORY
{
PAGE 0:
VECS: origin=8000h, length=0040h
PVECS: origin=8044h, length=0100h
PM: origin=8100h, length=0200h
....
试试，如没有中断，应该会好使得。
谢谢你
可我的程序是要用中断的,
而且我看书上的程序都是从0000h开始的a,
为什么要从8000h开始?
小弟新学,请问还有别的什么方法来设置吗
比如改gel文件?
