在开发板运行uClinux后,我这样擦除Flash怎不功?

#define AM_START_ADDR 0x02000000 -------因运行uClinux时Flash地址被映射到0x02000000

int earaFlash()
{
    printf("Start easraFlash!\n");
    *((volatile UINT16 *)AM_START_ADDR+ AM_ADDR_UNLOCK1) = AM_DATA_UNLOCK1;
    *((volatile UINT16 *)AM_START_ADDR+ AM_ADDR_UNLOCK2) = AM_DATA_UNLOCK2;
    *((volatile UINT16 *)AM_START_ADDR+ AM_ADDR_UNLOCK1) = AM_SETUP_ERASE;
    *((volatile UINT16 *)AM_START_ADDR+ AM_ADDR_UNLOCK1) = AM_DATA_UNLOCK1;
    *((volatile UINT16 *)AM_START_ADDR+ AM_ADDR_UNLOCK2) = AM_DATA_UNLOCK2;
    *((volatile UINT16 *)AM_START_ADDR+ AM_ADDR_UNLOCK1) = AM_CHIP_ERASE;
    printf("End easraFlash!\n");
    return(0);
}
