DSP2812的CMD空间大小设置问题

我的cmd程序如下：

MEMORY

PAGE 0 :

/* SARAM H0 is split between PAGE 0 and PAGE 1 */
PRAMH0 : origin = 0x3f8000 length = 0x002000

/* This memory block loaded with the reset vector only if
booting from XINTF Zone 7. Otherwise reset vector is
fetched from boot ROM. See .reset section below */

PAGE 1 :

/* CSM Password Locations */
CSM_PWL : origin = 0x3F7FF8, length = 0x000008

/* SARAM H0 is split between PAGE 0 and PAGE 1 */
DRAMH0 : origin = 0x3f9000, length = 0x002000
}

}

报错位置如图所示

有两个问题：

1、.econst的空间大小怎么增大？

2、PRAMH0和DRAMH0的大小怎么增大？这个length大小怎么计算的？对应的origin是不是也要更改？主要是这个0x巴拉巴拉的部分计算我不太会。。。

谢谢懂得人士的指导~
