我随便打开一个例程，连接好板子，debug，然后用memory browser查看内存，比如0xc3000000,就会发现里面已经有数据了，这个数据是从哪来的呢？它掉电没被擦除掉难道是属于flash段么？那怎么在debug时让它初始化为0呢、、
随便还想请教一下怎么查询各ram，rom的起始地址，还有flash为什么要烧写而不是像DDR一样直接在cmd里划定~？
谢谢了，正在迷茫中:(
下面是例程的cmd代码
MEMORY
{
L2: o = 0x00800000 l = 0x00040000
share: o = 0x80000000 l = 0x00020000
L1P: o = 0x00E00000 l = 0x00008000
L1D: o = 0x00F00000 l = 0x00008000
dsp_ddrii: o = 0xc2000000 l = 0x1000000
}

}
下面是生成的map文件
