我用的是一块LPC2103的最小系统板配的自己焊接的电路，在FLASH中调试的时候出现下面的
以下是我用IAR EWARM 时的调试信息：Fri Sep 02 21:27:28 2011: Loaded macro file: E:\IAR Systems\Embedded Workbench 4.0 Evaluation\arm\config\flashloader\NXP\FlashNXPLPC32k.mac

这是我在Flash中的仿真开始时的信息
以下是我在单步调试到while循环时出现的现象：
Fri Sep 02 21:30:57 2011: Failed to set breakpoint at 0x00000A00 (out of hardware breakpoints)
Fri Sep 02 21:30:57 2011: Performance warning: Lack of breakpoints forces single-stepping.
Fri Sep 02 21:30:59 2011: Failed to set breakpoint at 0x00000A00 (out of hardware breakpoints)
Fri Sep 02 21:30:59 2011: Performance warning: Lack of breakpoints forces single-stepping.
我不知道是什么原因能不能帮我解释一下? 我写的代码太大，12K，不能在RAM中仿真，只能在Flash中仿真 是不是这里人比较少啊？
