我使用 IMPACT将leon提供的LEON3比特流下载到ml510开发板上，使用1.1.49的GRMON进行调试。我使用load语句下载可执行文件，但总是报错说：
warning: stack pointer not set
IU in error mode (tt = 0x02 )
40000000 00000000 unimp
请问有没有哪位高手知道这是怎么回事啊？
另外，我注意到在GRMON连接到开发板后所显示的配置信息与所提供的文档中记录的不一样,虽然文档中是以LEON2为例，但是有的地方还是值得注意。
下面是我自己调试时窗口显示的信息：

根据我的提示no sram found，而文档提供的是找到了sram，有可能我的找不到sram，但是我的开发板上连接了两个DDR2（虽然我不知道它们好不好使），我应该怎么解决这个问题呢，求高手指点! |
