CCS内存分配问题
在下用的是DSP：DM642，编程用C,平台CCS3.1,计算机仿真。程序在TC上能跑，但是到CCS上提示：Trouble running Target CPU: Memory Map Error: WRITE access by Default to address 0xffffe1c8, which is RESERVED in Hardware.
是不是lnk.cmd的问题，还是DM642sim.gel文件的问题？跪求各位大侠了，在下当以分报之：
附上lnk.cmd文件和DM642sim.gel文件：
-stack 0x500
-heap 0x500

{
L2 : o = 00000000h l = 40000h /* all SRAM */
CE0: o = 80000000h l = 2000000h /* external memory */
}

我最近在调试的程序也出现这种问题，正在思考，不知道你的解决没有，如果解决了，希望可以分享一下解决方案，谢谢了
