目录(?)[+]

一、开发环境

我的开发环境：

lUbuntu 12.10

lJlink V8

lJLink_Linux_V422a.tgz

二、步骤

1、安装JLlink V8 Linux驱动

l从官网下载：http://www.segger.com/cms/jlink-software.html

lLinux环境下解压缩，阅读README，按照步骤进行配置

1.apt-get update

apt-get install libusb

安装libusb，但是提示找不到libusb，大概是我的环境的软件源的问题，不去管他。

到lib目录下查找，发现有已经有了libusb，这一步可以跳过。

2.cp libjlinkarm.so.* /usr/lib

ldconfig

复制jlink自己的库文件到/usr/lib，如果使用README上提供的命令会发现，复制过去的文件中，链接文件变成了普通文件，为了使链接文件复制前后保持一致，cp命令需要加上-d选项，或者复制后再用ln命令重新建立链接。

3.cp 45-jlink.rules /etc/udev/rules.d/

4.最后一步是要建立一个用户组，因为我都是超级用户登录的，没有必要，略过。

2、开始试验

升级Jlink固件。如果能想办法把jlink升级到最新的固件，那即便用最新的驱动软件应该也不会提示升级固件了。Linux下是不可以了，似乎不能成功，Windows可以试一试。下载了Windows版本的Jlink驱动V442b，安装后连接Jlink，果然提示升级，升级后发现也不行，固件似乎也不能运行，Jlink Commander停在了“New firmware booted successfully”这里，我的Jlink大概不能兼容最新的固件。软件换回V422a版本，重新连接Jlink，竟然发现固件升级成功了，而且也可以连接到开发板，简单测试没有发现问题。回到Linux下使用V441g版本连接，正常连接。

Ubuntu 10.04下J-Link配置及使用2011-07-27 17:16:04

分类： 嵌入式

摘要： 本文介绍了如何在Ubuntu平台配置J-Link，因版本较高，网上一些资料已不适用，根据J-Link的README文件操作，会产生诸多问题，本文对产生问题的原因进行简单分析，并给出解决方法。最后给出J-Link基本用法。1 引言 最近因项目需要，需要配置Linux下的J-Link工具，网上有一博文《ubuntu 9.04下J－Link for linux 的配置与使用》，介绍得蛮详细的，但在实际操作过程中差别甚大，应该是版本的原因(我用的是Ubuntu 10.04LTS和JLink_Linux_V430)。 JLink_Linux_V430安装包里的README文件，介绍了如何配置，过于简单，而且安装过程中会遇到不少问题，遂记录整个过程，以供分享。2 J-Link配置2.1安装libusb 如果J-Link是通过USB连接的，得先装libusb，README文件声称用apt-get install libusb，在我机器上不行，提示“无法找到软件包”。所以得自己下载安装。 在http://sourceforge.net/projects/libusb/files/libusb-1.0/下载(libusb官网，http://www.libusb.org/)，并安装，整个过程多次需要root权限，可通过命令sudo -s一次性取得root权限：

root@jelline:~/Downloads# tar jxvf libusb-1.0.8.tar.bz2root@jelline:~/Downloads# cd libusb-1.0.8/root@jelline:~/Downloads/libusb-1.0.8#./configureroot@jelline:~/Downloads/libusb-1.0.8# makeroot@jelline:~/Downloads/libusb-1.0.8# make install

2.2 安装libreadline JLinkExe会用到libreadline库，所以得把libreadline库装上。http://cnswww.cns.cwru.edu/php/chet/readline/rltop.html中Current Status选择下载，并安装，如下所示：

root@jelline:~/Downloads# tar-zxvf readline-6.2.tar.gzroot@jelline:~/Downloads/readline-6.2#./configureroot@jelline:~/Downloads/readline-6.2# makeroot@jelline:~/Downloads/readline-6.2# make install

2.3 下载Beta software version for Linux 到http://www.segger.com/cms/jlink-software.html下载Beta software versionfor Linux，提示输入序列号，随便输入一串数字即可，点submit serial number，接着在I confirm that I will not use the software with illegal clones打勾，而后Download Software。拷贝库，并执行ldconfig，具体如下：

jelline@jelline:~/Downloads$ tar zxvf JLink_Linux_V430.tgzjelline@jelline:~/Downloads/JLink_Linux_V430$ cp libjlinkarm.so.4*/usr/libjelline@jelline:~/Downloads/JLink_Linux_V430$ ldconfig

上述是依README指示操作，会报如下错误：

/sbin/ldconfig.real: /usr/lib/libjlinkarm.so.4 is not a symbolic link

问题出在把libjlinkarm.so.4拷贝到/usr/lib就不再是符号链接文件(这点我也纳闷)，进入到/usr/lib目录下，删除libjlinkarm.so.4，并重新建立符号链接文件即可，如下：

root@jelline:/usr/lib# rm libjlinkarm.so.4root@jelline:/usr/lib# ln-s libjlinkarm.so.4.30.0 libjlinkarm.so.4root@jelline:/usr/lib# ldconfig

为了让标准用户有权使用JLinkExe(这句话是README翻译过来的)，还需要进行如下操作：

root@jelline:~/Downloads/JLink_Linux_V430# cp 45-jlink.rules/etc/udev/rules.d/root@jelline:~/Downloads/JLink_Linux_V430# groupadd plugdevroot@jelline:~/Downloads/JLink_Linux_V430# usermod-a -G plugdev jelline

2.4 测试按README文件，貌似已经装好了，但执行JLinkExe，仍提示如下错误：

root@jelline:~/Downloads/JLink_Linux_V430#./JLinkExeerror while loading shared libraries: libreadline.so.5: cannot open shared object file: No such file or directory

在/usr/lib找不到libreadline.so.5库，最后发现libreadline.so库被放在/lib/下，但其版本是6，创建一个符号链接指向libreadline.so.6.1，具体如下：

jelline@jelline:/lib$ ls libreadline.so.6*libreadline.so.6 libreadline.so.6.1jelline@jelline:/lib$ ln-s libreadline.so.6.1 libreadline.so.5

OK，现在重新运行JLinkExe就可以了，提示如下信息：

3 使用JLink在J-Link>输入"?"，即给出命令列表。我在使用过程中，总体觉得Linux下JLink不够成熟，主要表现在资料太小、功能不易用、操作成功与否不提示(当然不排除不熟练的原因)。3.1 下载loadbinloadbin用于将二进制文件下载到目标存储器，语法如下：

Syntax: loadbin <filename>, <addr> //Load binary file into target memory

下载之前需要设置下目标版的处理器，否则无法正常烧写，我的型号是STM32F103RBT6，但在指定的时候只指定为STM32F103RB，如下：

J-Link>exec device = STM32F103RB

有个麻烦，下载完没有明显提示成功与否，可以通过这样解决：在PC通过命令xxd查看待下载文件，下载进去通过JLink命令mem查看，判断这两者是否一样(只比较前面若干字节即可)，若一样，则表示烧写成功。举个例子，把/bin/cp文件烧到板子：

J-Link>loadbin /bin/cp, 0x08000000Loading binary file… [/bin/cp]Writing bin data into target memory @ 0x08000000.J-Link>mem 0x08000000,3f08000000 = 7F 45 4C 46 01 01 01 00 00 00 00 00 00 00 00 0008000010 = 02 00 03 00 01 00 00 00 40 A1 04 08 34 00 00 0008000020 = 04 73 01 00 00 00 00 00 34 00 20 00 09 00 28 0008000030 = 1D 00 1C 00 06 00 00 00 34 00 00 00 34 80 04jelline@jelline:~$ xxd /bin/cp | more0000000: 7f45 4c46 0101 0100 0000 0000 0000 0000 .ELF…………0000010: 0200 0300 0100 0000 40a1 0408 3400 0000 ……..@…4…0000020: 0473 0100 0000 0000 3400 2000 0900 2800 .s……4. …(.0000030: 1d00 1c00 0600 0000 3400 0000 3480 0408 ……..4…4…

3.2 保存savebin

Syntax: savebin <filename>, <addr>, <NumBytes> //Saves target memory into binary file

这里值得一提的是，参数<NumBytes>是十六进制，比如指定10，保存的是16个字节。我最开始误以为是十进制，我通过ls命令，发现文件大小与自己预期不一致，对比实际文件与预期大小，才发现这个问题。命令mem的<NumBytes>也是十六进制的。　　尽管版本不一，具体配置还需依情况而定，希望本文有启发作用。PS：我刚开始用，欢迎交流！Jelline@126.com@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

Problem SolvedWell, wrong ELF class: ELFCLASS64 is anerror caused when we try to execute one 32bit app with one 64bit lib. So, I discover that I need to do one symbolic link to the 32bit lib instead the one into /lib system folder (amd64-Kernel). Using the apt-file search libreadline.so I got
