dsp2812外扩一个521kx16RAM的CMD文件编写

在zone6区域外扩一个521kx16RAM,改写程序如下，请教有无问题，flash与ram编写有什么不同？外扩ram有一部分用于程序：
MEMORY
{
PAGE 0 :
BEGIN    : origin ＝ 0x100000, length = 0x000002
PRAMH0    : origin = 0x3F8000, length = 0x001000

PAGE 1 :
/* SARAM                   */
RAMM0    : origin = 0x000000, length = 0x000400
RAMM1    : origin = 0x000400, length = 0x000400

/* SARAM                   */
ZONE6    : origin = 0x10002, length = 0x07FFFFE
.......
}
SECTIONS
{
/* Allocate program areas: */
codestart       : > BEGIN,    PAGE = 0

.reset          : > PRAMH0,    PAGE = 0 ,TYPE=DSECT

.text          : > PRAMH0,    PAGE = 0
.cinit          : > PRAMH0,    PAGE = 0
.pinit          : > PRAMH0,    PAGE = 0
.switch       : > PRAMH0,    PAGE = 0
/* Allocate data areas: */
.stack          : > RAMM1,    PAGE = 1
.bss          : > ZONE6,    PAGE = 1
.ebss          : > ZONE6,    PAGE = 1
.const          : > ZONE6,    PAGE = 1
.econst       : > ZONE6,    PAGE = 1
.sysmem       : > ZONE6,    PAGE = 1
.esysmem       : > ZONE6,    PAGE = 1
......
}
