TI官方的CMD文件说明

sick

TI官方提供的CMD文件有三个: 28335_RAM_lnk.cmd、F28335.cmd、DSP2833x_Headers_nonBIOS.cmd


调试程序时，将28335_RAM_lnk.cmd文件加入工程中，程序被加载到SRAM中运行。
实际的产品运行时，需要将程序下载到FLASH中，并从FLASH中启动，这时需要
在工程中加入F28335.cmd文件，同时屏蔽28335_RAM_lnk.cmd文件。


TI官方文件F28335.cmd对内部SRAM的分配如下:


BOOT_RSVD : origin = 0x000000, length = 0x000050 // Part of M0, BOOT rom will use this for stack PAGE 1
RAMM0 : origin = 0x000050, length = 0x0003B0 // on-chip RAM block M0 PAGE 1
RAMM1 : origin = 0x000400, length = 0x000400 // on-chip RAM block M1 PAGE 1


ZONE0 : origin = 0x004000, length = 0x001000 // XINTF zone 0 PAGE 0


RAML0 : origin = 0x008000, length = 0x001000 // on-chip RAM block L0 PAGE 0
RAML1 : origin = 0x009000, length = 0x001000 // on-chip RAM block L1 PAGE 0
RAML2 : origin = 0x00A000, length = 0x001000 // on-chip RAM block L2 PAGE 0
RAML3 : origin = 0x00B000, length = 0x001000 // on-chip RAM block L3 PAGE 0
RAML4 : origin = 0x00C000, length = 0x001000 // on-chip RAM block L1 PAGE 1
RAML5 : origin = 0x00D000, length = 0x001000 // on-chip RAM block L1 PAGE 1
RAML6 : origin = 0x00E000, length = 0x001000 // on-chip RAM block L1 PAGE 1
RAML7 : origin = 0x00F000, length = 0x001000 // on-chip RAM block L1 PAGE 1


Allocate DMA-accessible RAM sections:
DMARAML4 : > RAML4, PAGE = 1
DMARAML5 : > RAML5, PAGE = 1
DMARAML6 : > RAML6, PAGE = 1
DMARAML7 : > RAML7, PAGE = 1


Allocate uninitalized data sections:
.stack : > RAMM1 PAGE = 1
.ebss : > RAML4 PAGE = 1
.esysmem : > RAMM1 PAGE = 1
