TMS320LF2406调试心得.doc

TMS320LF2406调试心得：由于TMR320LF2406没有外部SRAM扩展(没有MP功能)，而调试只能在RAM中进行，所以只能利用片内的2K的SARAM进行调试(8000H-87FFH)。第一步：烧写，把正常程序烧写到DSP中，其中通过跳转命令跳到8000H中以便以后进行调试。最简单的就是在复位的中断向量处B 8000H，这样每次复位都跳到8000H而不是FLASH中。;=Test.asm文件=.global _c_int0 .globalPHANTOM.include f2407.h.bssD1,1;-程序开始-.text_c_int0:;-系统初始化-LDP#0hSETCINTM;关闭中断CLRCSXM;允许/禁止符号扩展，若允许则SETCSXMCLRCCNF;若要B0为数据存储器则CRLCCNFSETCOVM;溢出方式设置LDP#00E0HSPLK#8380h,SCSR1;CLKOUT=2*fin,所有功能禁止使能SPLK#0040H,D1OUTD1,WSGRSPLK#00E8h,WDCR;禁止看门狗LDP#0SPLK#0,IMRSPLK#0FFFFH,IFRLDP#000E1hSPLK#0000h,MCRA;SPLK#0FF00h,MCRB;MCRB控制的端口前8位是JTAG相关端口，故设为1SPLK#0000h,MCRC;所有的端口都设为I/O端口SPLK#0C43Bh,PADATDIRSPLK#0FF0h,PBDATDIRSPLK#00FFh,PCDATDIRSPLK#0AF5h,PEDATDIRSPLK#0000h,PFDATDIR;-主循环-MAIN:LDP#00E1hSPLK#0C43Bh,PADATDIRSPLK#0FF8h,PBDATDIRSPLK#0C43Fh,PADATDIRSPLK#0FF0h,PBDATDIRBMAIN;-假中断程序-PHANTOM:RET .end;= Vector.asm = .ref _c_int0 .refPHANTOM .sect .vectorsRESET B 8000H ;00h resetINT1: B PHANTOM ;02h INT1INT2: B PHANTOM ;04h INT2INT3: B PHANTOM ;06h INT3INT4: B PHANTOM ;08h INT4INT5: B PHANTOM ;0Ah INT5INT6: B PHANTOM ;0Ch INT6RESERVED: B PHANTOM ;0Eh reservedSW_INT8: B PHANTOM ;10h INT8 user-definedSW_INT9: B PHANTOM ;12h INT9 user-definedSW_INT10: B PHANTOM ;14h INT10 user definedSW_INT11: B PHANTOM ;16h INT11 user definedSW_INT12: B PHANTOM ;18h INT12 user definedSW_INT13: B PHANTOM ;1Ah INT13 user definedSW_INT14: B PHANTOM ;1Ch INT14 user definedSW_INT15: B PHANTOM ;1Eh INT15 user definedSW_INT16: B PHANTOM ;20h INT16 user definedTRAP: B PHANTOM ;22h TRAPNMI: B PHANTOM ;24h NMIEMU_TRAP: B PHANTOM ;26h reservedSW_INT20: B PHANTOM ;28h INT20 user definedSW_INT21: B PHANTOM ;2Ah INT21 user definedSW_INT22: B PHANTOM ;2Ch INT22 user definedSW_INT23: B PHANTOM ;2Eh INT23 user definedSW_INT24: B PHANTOM ;30h INT24 user definedSW_INT25: B PHANTOM ;32h INT25 user definedSW_INT26: B PHANTOM ;34h INT26 user definedSW_INT27: B PHANTOM ;36h INT27 user definedSW_INT28: B PHANTOM ;38h INT28 user definedSW_INT29: B PHANTOM ;3Ah INT29 user definedSW_INT30: B PHANTOM ;3Ch INT30 user definedSW_INT31: B PHANTOM ;3Eh INT31 user defined;=cmd文件=MEMORY PAGE 0: VECS: origin = 0000h, length = 0040h PROG: origin = 0044h, length = 7FBCh PAGE 1: B0B1: origin = 0200h, length = 200h SARAM: origin = 8000h, length = 1000h SECTIONS .vectors : VECS PAGE = 0H .text : PROG PAGE = 0 .data : B0B1 PAGE 1 .bss : SARAM PAGE 1 .stack : SARAM PAGE 1 .sysmem : SARAM PAGE 1第二步：调试，单独写一个调试的程序，放入一个段中，然后把这个段定位到8000H处，就可以进行调试了。;=test.asm= .include f2407.h.bssD1,1;-程序开始-.text_c_int0:;-系统初始化-LDP#0hSETCINTM;关闭中断CLRCSXM;允许/禁止符号扩展，若允许则SETCSXMCLRCCNF;若要B0为数据存储器则CRLCCNFSETCOVM;溢出方式设置LDP#00E0HSPLK#8380h,SCSR1;CLKOUT=2*fin,所有功能禁止使能SPLK#0040H,D1OUTD1,WSGRSPLK#00E8h,WDCR;禁止看门狗？LDP#0SPLK#0,IMRSPLK#0FFFFH,IFRLDP#000E1hSPLK#0000h,MCRA;SPLK#0FF00h,MCRB;MCRB控制的端口前8位是JTAG相关端口，故设为1SPLK#0000h,MCRC;所有的端口都设为I/O端口SPLK#0C43Bh,PADATDIRSPLK#0FF0h,PBDATDIRSPLK#00FFh,PCDATDIRSPLK#0AF5h,PEDATDIRSPLK#0000h,PFDATDIR;-主循环-MAIN:;计算载波比LDP#00E1hSPLK#0C43Bh,PADATDIRSPLK#0FF8h,PBDATDIRSPLK#0C43Fh,PADATDIRSPLK#0FF0h,PBDATDIRBMAIN;-假中断程序-PHANTOM:RET .end;=cmd文件=MEMORY PAGE 0:SPROG: origin = 8000h, length = 700h PAGE 1: B0B1: origin = 0200h, len
