6747栈溢出的问题

我的linkercmd的配置如下所示，将.stack段放在L2RAM中，程序每次都会发生栈数据溢出的情况，将.stack段放在shareram中，程序会偶尔发生栈数据溢出的情况，为什么？可以确认程序的逻辑是正确的，VC同样的程序跑起来没有问题

-stack 0x00004000 /* Stack Size */
-heap 0x00004000 /* Heap Size */

VECS: o = 0x11800000 l = 0x00000200

SHAREDRAM: o = 0x80000000 l = 0x00020000
SDRAM: o = 0xC1000000 l = 0x02fe0000

自己不觉得这cmd文件有问题吗？同一个空间写两遍。ROM， L1写到memory里干什么？

DSPL2RAM, DSPL2RAM2属于同一块物理地址。
