1、软件eclipse ， GDB Server ， Jlink软件硬件 Jlink硬件准备工作1：从SD/NOR Flash启动，格式化nand flash准备工作2：硬件连接1. Jlink连接2. 串口连接3.nand启动
2、解压：tar xvzf arm-linu垓矗梅吒x-gdb-7.5.tar.gz进入目录：cd arm-linux-gdb-7.5编译安装：./build幻腾寂埒-all上面执行好后，gdb工具就安装好了，安装在/opt/arm-linux-gdb为了方便使用，需要添加环境变量：vim /root/.bashrc在交叉编译链的前面添加gdb的环境变量：export PATH=$PATH:/opt/arm-linux-gdb/bin/export PATH=$PATH:/usr/local/arm/4.3.2/bin/之后保存，退出。这就可以直接运行arm-linux-gdb，如果不行的话则可能是添加错误，或者需要注销。
3、解压：tar xvzf JLink_Li艘绒庳焰nux_V434a.tgz进入目录：cd JLink_Linux_V434a复制库：cp -d libjlinkarm.so* /usr/lib -f复制：cp 45-jlink.rules /etc/udev/rules.d/上面四个命令执行完之后，检测是否能够检测到Jlink的连接：在虚拟机的下面，点击显示为Jlink相关的usb图标，连接。执行命令：./JLinkGDBServer如果也切顺利的话，会显示连接上的ARM核心为ARM11：
4、安装eclipse：解压：tar zxvf eclipse-cpp-helios-SR2-linux-gtk.tar.gz进入目录：cd eclipse-cpp-helios-SR2-linux-gtk运行程序：./eclipse然后选择自己的工程目录：
5、首先得安装一个插件点菜单栏的help -> install new software在Work with输入插件位置：http://opensource.zylin.com/zylincdt,点击add等一段时间，找到的插件，点击选中：
6、点击next；
7、之后按照提示来。然后重启：
8、使用eclipse进行开发新建工程，选择新建一个已存在源文件的工程：
9、注意：这里的源文件目录必须是在工作目录下的另外一个目录，比如工作目录是"/home/S3-ARM/Part1/lesson1"，那么【Existing Code Locat足毂忍珩ion】的目录为不能和工作目录相同，必须是别的目录，或者是工作目录下的一个子目录，比如"/home/S3-ARM/Part1/lesson1/led/"或者是"/opt/led/"
10、点击finish。编译项目：Project ---Build AlL注意：取消掉【Project】里面的自动编译【Build Automatically】
11、配置调试器：甲虫图---Debug Configurations
12、双击Zylin Embedded debu，出现下面界面：
13、选中选项卡main在C/C++ Application中选要调试的项目，注意是选中 "xxx.elf" 文件:
14、选中选项卡Debugger去掉Stop on startup at:选项将GDB debugger: 修改成" arm-linux-gdb "
15、选中选项卡Comma艘绒庳焰nds在'Initialize' commands中填入如下初始化指令：下面是初始化S3C鲂番黟谊6410处理器的初始化脚本1 # tiny6410_config 2 # connect to the J-Link gdb server 3 target remote localhost:2331 4 # Set JTAG speed to 30 kHz 5 monitor endian little 6 monitor speed 30 7 # Reset the target 8 monitor reset 9 monitor sleep 1010 #11 # CPU core initialization (to be done by user)12 #13 # Set the processor mode14 monitor reg cpsr = 0xd315 #config MMU16 #flush v3/v4 cache17 monitor cp15 7, 7, 0, 0 = 0x018 #/* flush v4 TLB */19 monitor cp15 8, 7, 0, 0 = 0x020 #disable MMU stuff and caches21 monitor cp15 1, 0, 0, 0 =0x100222 #Peri port setup23 monitor cp15 15, 2, 0, 4 = 0x7000001324 #disable watchdog25 monitor MemU32 0x7e004000 = 0x0000000026 monitor sleep 1027 #disable interrupt28 monitor MemU32 0x71200014 = 0x0000000029 monitor MemU32 0x71300014 = 0x0000000030 monitor MemU32 0x7120000C = 0x0000000031 monitor MemU32 0x7130000C = 0x0000000032 monitor MemU32 0x71200F00 = 0x0000000033 monitor MemU32 0x71300F00 = 0x0000000034 #set clock35 monitor MemU32 0x7e00f900 = 0x0000801e36 monitor MemU32 0x7e00f000 = 0x0000ffff37 monitor MemU32 0x7e00f004 = 0x0000ffff38 monitor MemU32 0x7e00f020 = 0x0104331039 monitor MemU32 0x7e00f00C = 0xc215060140 monitor MemU32 0x7e00f010 = 0xc215060141 monitor MemU32 0x7e00f024 = 0x0000000342 monitor MemU32 0x7e00f014 = 0x0020010243 monitor MemU32 0x7e00f018 = 0x0000000044 monitor MemU32 0x7e00f01C = 0x1400000745 #config sdram46 monitor MemU32 0x7e00f120 = 0x0000000847 monitor MemU32 0x7e001004 = 0x0000000448 monitor MemU32 0x7e001010 = 0x0000040f49 monitor MemU32 0x7e001014 = 0x0000000650 monitor MemU32 0x7e001018 = 0x0000000151 monitor MemU32 0x7e00101c = 0x0000000252 monitor MemU32 0x7e001020 = 0x0000000653 monitor MemU32 0x7e001024 = 0x0000000a54 monitor MemU32 0x7e001028 = 0x0000000c55 monitor MemU32 0x7e00102c = 0x0000018f56 monitor MemU32 0x7e001030 = 0x0000000c57 monitor MemU32 0x7e001034 = 0x0000000258 monitor MemU32 0x7e001038 = 0x0000000259 monitor MemU32 0x7e00103c = 0x0000000260 monitor MemU32 0x7e001040 = 0x0000000261 monitor MemU32 0x7e001044 = 0x0000001362 monitor MemU32 0x7e001048 = 0x0000001363 monitor MemU32 0x7e00100C = 0x0001001264 monitor MemU32 0x7e00104C = 0x00000b4565 monitor MemU32 0x7e001200 = 0x000150f866 monitor MemU32 0x7e001304 = 0x0000000067 monitor MemU32 0x7e001008 = 0x000c000068 monitor MemU32 0x7e001008 = 0x0000000069 monitor MemU32 0x7e001008 = 0x0004000070 monitor MemU32 0x7e001008 = 0x0004000071 monitor MemU32 0x7e001008 = 0x000a000072 monitor MemU32 0x7e001008 = 0x0008003273 monitor MemU32 0x7e001004 = 0x0000000074 # Setup GDB for faster downloads75 #set remote memory-write-packet-size 102476 set remote memory-write-packet-size 409677 set remote memory-write-packet-size fixed78 monitor speed 1200079 break _start80 load

17、开始调试用eclipse调试 ，保证JLinkGDBServer同时在运行
18、保证JLinkGDBServer运行起来了，点击小甲壳虫 -- 项目名开始进调试界面
19、选择 yes
20、调试界面如下图
21、点击【F5】是"Step Into"【F6】是"Step Over"等等，这里可以查看寄存器的值，没存的值等等。一步一步下去可以看到开发板上的led点亮了。
