arm蛋疼汇编 part6--写程序怎能不调试 eclipse cdt zylincdt openocd gdb 调试

step1：安装eclipse   cdt  这个google search 一大堆   archlinux  下 yaourt  直接             搞定

step2：在线安装安装eclipse  zylincdt插件   eclipse下  Help==>install new                    software==>work with:  zylincdt -                                                                  http://www.zylin.com/zylincdt 剩下的google search一堆

step3：安装openocd   yaourt搞定最新版  配置文件如下：

[leftover-crazy@leftover-crazy ~]$ vim .openocd/openocd.cfg 

# # 100ASK OpenJTAG # # http://www.100ask.net # interface ft2232 ft2232_device_desc "USB<=>JTAG&RS232 A" ft2232_layout jtagkey ft2232_vid_pid 0x1457 0x5118 # Target configuration for the Samsung 2440 system on chip # Tested on a S3C2440 Evaluation board by keesj # Processor : ARM920Tid(wb) rev 0 (v4l) # Info: JTAG tap: s3c2440.cpu tap/device found: 0x0032409d (Manufacturer: 0x04e, Part: 0x0324, Version: 0x0) if { [info exists CHIPNAME] } { set _CHIPNAME $CHIPNAME } else { set _CHIPNAME s3c2440 } if { [info exists ENDIAN] } { set _ENDIAN $ENDIAN } else { # this defaults to a bigendian set _ENDIAN little } if { [info exists CPUTAPID ] } { set _CPUTAPID $CPUTAPID } else { # force an error till we get a good number set _CPUTAPID 0x0032409d } #jtag scan chain jtag newtap $_CHIPNAME cpu -irlen 4 -ircapture 0x1 -irmask 0x0f -expected-id $_CPUTAPID set _TARGETNAME $_CHIPNAME.cpu target create $_TARGETNAME arm920t -endian $_ENDIAN -chain-position $_TARGETNAME -variant arm920t $_TARGETNAME configure -work-area-phys 0x200000 -work-area-size 0x4000 -work-area-backup 1 #reset configuration jtag_nsrst_delay 100 jtag_ntrst_delay 100 reset_config trst_and_srst jtag_khz 12000 #gdb_breakpoint_override hard arm7_9 dcc_downloads enable arm7_9 fast_memory_access enable nand device 0 s3c2440 0 

step4： crosstool-ng 编译交叉工具链 生成如下工具：

arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-addr2line arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-addr2name.awk arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-ar arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-as arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-c++ arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-cc arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-c++filt arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-cpp arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-ct-ng.config arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-g++ arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-gcc arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-gcc-4.3.2 arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-gccbug arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-gcj arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-gcov arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-gdb arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-gdbtui arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-gfortran arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-gprof arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-jcf-dump arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-ld arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-ldd arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-nm arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-objcopy arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-objdump arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-populate arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-ranlib arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-readelf arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-run arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-size arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-sstrip arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-strings arm/arm-2440-linux-gnueabi/bin/arm-2440-linux-gnueabi-strip  

   此步骤也是google search  呵呵

step5：新建empty makefile工程    以下截图说明：

FILE==>c project 选择makefile project ==》empty project==》选择other toolchain 并填写工程名称

 

next==>next==>finish

test project 右键 properties  ==》Settings 修改如下：

 

discovery option 修改如下：

 

接着就可以新建代码文件以及makefile了简单实例如下：

makefile：

all: test.S arm-2440-linux-gnueabi-as -g test.S -o test.o arm-2440-linux-gnueabi-ld -Ttext=0x0 test.o -o test_elf arm-2440-linux-gnueabi-objdump -d -m arm test_elf > test_elf.dis arm-2440-linux-gnueabi-objcopy -I elf32-littlearm test_elf -O binary test.bin clean: rm -f test.o test_elf test_elf.dis test.bin  

test.S:

main: @压栈操作 nop nop ldr sp, =2000 mov ip, sp sub sp, sp, #12 str lr, [sp] @str r14, [sp] str ip, [sp, #4] @ str r12, [sp, #4] str fp, [sp, #8] @ str r11. [ip, #8] sub fp, ip, #4 @函数调用 ldr r0, =hello @取hello标签地址给R0 既参数一的地址 @arm汇编参数传递通过 @R0传递第一个参数 @R1传递第二个参数 @R2传递第三个参数 @R3传递第四个参数 @如果有多于四个参数的传递需要使用堆栈 @sub sp,sp,#4 @mov lr, pc @ldr pc, show @出栈操作 ldr lr, [fp, #-8] ldr ip, [fp, #-4] ldr fp, [fp, #0] mov sp, ip @函数返回 mov pc,lr show: .word 0x33f9303c hello: .asciz "hello Uboot part2! /n"  

接着取消选中project下的 Build Automaticlly

build project 执行make all    clean project 执行make clean

 

 

step6：openocd 配合gdb调试工程配置

选择下的debug configurations     双击zylin embedded debug（native）设置如下：

 

以下仅修改gdb工具：断点入口可以指定任意lable

 

接着修改启动时的初始命令  monitor开头的是相对于openocd的   其余为gdb的  代码如下：（参照图片修改）

target remote 127.0.0.1:3333 monitor arm920t cp15 2 0 monitor arm7_9 dbgrq enable monitor halt load break main continue 

接着点击apply即可

 

启动openpcd   可以在external  tool configurations 设置  也可以直接命令行启动  

点击下的external  tool configurations  设置如下两步：

 

 

 

 

step7：以上已经完成了所有的配置    下次用到时直接copy project   做相应的简易修改即可

下面是调试过程：  1启动openocd  下拉选择openocd   调试过程中openocd在未停止状态下  只需启动一次

                          2开始调试 下拉选择 test default  

 

                           调试界面如下  剩下的和调试其它程序无差别了  google search  呵呵

 

                         收工   有够蛋疼的  嘿嘿
