你好，我在查看tmdxiddk379d的例程（C:\ti\c2000\C2000Ware_MotorControl_SDK_3_00_01_00\solutions\tmdxiddk379d\f2837x）的时候，发现其中的RAM cmd文件如下：

MEMORY
{
/* BEGIN is used for the "boot to SARAM" bootloader mode */
BEGIN : origin = 0x000000, length = 0x000002
BOOT_RSVD : origin = 0x000002, length = 0x0001AE /* Part of M0, BOOT rom will use this for stack */
RAMM0 : origin = 0x0001B0, length = 0x000250
RAMM1 : origin = 0x000400, length = 0x000400 /* on-chip RAM block M1 */
RAMD0 : origin = 0x00C000, length = 0x000800
RAMD1 : origin = 0x00C800, length = 0x000800
RAMLS0 : origin = 0x008000, length = 0x000800
RAMLS1 : origin = 0x008800, length = 0x000800
RAMLS2 : origin = 0x009000, length = 0x000800
RAMLS3 : origin = 0x009800, length = 0x000800
RAMLS4 : origin = 0x00A000, length = 0x000800

RAMGS2 : origin = 0x00F000, length = 0x001000
RAMGS3 : origin = 0x010000, length = 0x001000
RAMGS4 : origin = 0x011000, length = 0x001000
RAMGS5 : origin = 0x012000, length = 0x001000
RAMGS6 : origin = 0x013000, length = 0x001000
RAMGS7 : origin = 0x014000, length = 0x001000
RAMGS8 : origin = 0x015000, length = 0x001000
RAMGS9 : origin = 0x016000, length = 0x001000
RAMGS10 : origin = 0x017000, length = 0x001000
RAMGS11 : origin = 0x018000, length = 0x001000
RAMGS12 : origin = 0x019000, length = 0x001000
RAMGS13 : origin = 0x01A000, length = 0x001000
RAMGS14 : origin = 0x01B000, length = 0x001000
RAMGS15 : origin = 0x01C000, length = 0x001000

CPU1TOCPU2RAM : origin = 0x03A000, length = 0x000800
CPU2TOCPU1RAM : origin = 0x03B000, length = 0x000800

CANA_MSG_RAM : origin = 0x049000, length = 0x000800
CANB_MSG_RAM : origin = 0x04B000, length = 0x000800
RESET : origin = 0x3FFFC0, length = 0x000002

CLA1_MSGRAMLOW : origin = 0x001480, length = 0x000080
CLA1_MSGRAMHIGH : origin = 0x001500, length = 0x000080
}

对于CPU1TOCPU2RAM和CPU2TOCPU1RAM ，通过查看28379d的datasheet，发现这二者实际的起始和结束地址应该是如下：

即按照我的理解，这个地方的配置不应该是：

CPU2TOCPU1RAM : origin = 0x03F800, length = 0x000400
CPU1TOCPU2RAM : origin = 0x03FC00, length = 0x000400

实际上在打开一个empty_driverlib_main_cpu1的例程的时候，里面的cmd文件也是这么描述的：

因此我想请问，iddk例程里cmd文件的0x03A000和0x03B000又是指向何处呢？此外，RAMGSx的分配似乎和empty_driverlib_main_cpu1也是始终差了一个0x001000，iddk中的例程对于RAMGS15的分配，起始地址是0x01C000，而datasheet中的描述则是0x0001B000：
