    请问用的是哪款芯片？可以先参考non bios例程里的cmd文件。cmd文件具体的说明，请参考对应系列的Assembly language user guide.

    可以参考下面的写法。

    -heap 0x800
    -stack 0x1000

    MEMORY
    {
    /* Local L2, 1MB*/
    VECTORS: o = 0x00800000 l = 0x00000200
    LL2_RW_DATA: o = 0x00800200 l = 0x5FE00

    /* Shared L2 2MB*/
    SL2: o = 0x0C000000 l = 0x00200000

    /* External DDR3, upto 2GB per core */
    DDR3_CODE: o = 0x80000000 l = 0x01000000 /*set memory protection attribitue as execution only*/
    DDR3_R_DATA: o = 0x81000000 l = 0x01000000 /*set memory protection attribitue as read only*/
    DDR3_RW_DATA: o = 0x82000000 l = 0x06000000 /*set memory protection attribitue as read/write*/
    }

    SECTIONS
    {
    vecs > VECTORS

    .text > LL2_RW_DATA
    .cinit > LL2_RW_DATA
    .const > LL2_RW_DATA
    .switch > LL2_RW_DATA

    .stack > LL2_RW_DATA
    GROUP
    {
    .neardata
    .rodata
    .bss
    } > LL2_RW_DATA
    .far > LL2_RW_DATA
    .fardata > LL2_RW_DATA
    .cio > LL2_RW_DATA
    .sysmem > LL2_RW_DATA
    }
