How-to manual Installing a toolchain for Cortex-M3/STM32 on Ubuntu by Peter Seng
博主最近在电脑上自建了博客，以后会更多的用那个了，欢迎关注访问，里面也有很多有用资源：

一 安装openocd
在ubuntu下安装openocd
sudo apt-get install openocd
也可以到官网下载源码包自己编译
二 安装openjtag驱动
插上openjtag
user@ubuntu:~/$ lsusbBus 002 Device 005: ID 093a:2521 Pixart Imaging, Inc. Bus 002 Device 003: ID 1457:5118 First International Computer, Inc. OpenMoko Neo1973 Debug board (V2+)
第二个就是了,记下ID 1457:5118
sudo gedit /etc/udev/rules.d/45-ftdi2232-libftdi.rules
在里面添加
SYSFS{idProduct}=="5118", SYSFS{idVendor}=="1457", MODE="666", GROUP="plugdev"
权限666,使用openocd就不用sudo了.
sudo /etc/init.d/udev restart
拔下在插上就可以了.
三 使用openocd 连openjtag
JTAG接口配置文件openjtag.cfg.根据JTAG设备不同,修改下面
#interface configuration openjtag#############################interface ft2232ft2232_device_desc "USB<=>JTAG&RS232"ft2232_layout jtagkeyft2232_vid_pid 0x1457 0x5118
可以参考openocd目录下的文件:/usr/share/openocd/scripts/interface,主要是设备ID以及设备名字,可以通过dmesg | grep usb命令查看. 要烧录stm32f103就得有这个设备的相关配置,可以查看/usr/share/openocd/scripts/target/stm32f1x.cfg
这里把两个文件合在一起openocd.cfg

开始烧录:
< 1 > 在一个终端下执行:
openocd -f openocd.cfg
出现:
Open On-Chip Debugger 0.7.0 (2013-05-15-17:28)Licensed under GNU GPL v2For bug reports, readhttp://openocd.sourceforge.net/doc/doxygen/bugs.htmlInfo : only one transport option; autoselect 'jtag'adapter speed: 500 kHzadapter_nsrst_delay: 100jtag_ntrst_delay: 100cortex_m3 reset_config sysresetreqInfo : clock speed 500 kHzInfo : JTAG tap: stm32f1x.cpu tap/device found: 0x3ba00477 (mfg: 0x23b, part: 0xba00, ver: 0x3)Info : JTAG tap: stm32f1x.bs tap/device found: 0x06414041 (mfg: 0x020, part: 0x6414, ver: 0x0)Info : stm32f1x.cpu: hardware has 6 breakpoints, 4 watchpoints
没有提示出错,就表示连接上STM32了 .如果出现出错,就在开发板上按下RESET 键复位,查看BOOT0和BOOT1有没有设置出错.
< 2 > 在另一个终端下,输入:
telnet localhost 4444
依次输入:
reset haltflash probe 0stm32f1x mass_erase 0flash write_bank 0 /you_stm32_project_dir/main.bin 0reset run
程序就烧好了,按下reset键,就开始运行了.
要输入这么多命令太麻烦了,写个perl脚本使它一步运行.
首先安装perl-telnet
sudo apt-get install libnet-telnet-perl
在工程目录下新建do_flash.pl文件
#!/usr/bin/perluse Net::Telnet;$numArgs = $#ARGV + 1;if($numArgs != 1){ die( "Usage ./do_flash.pl [main.bin] \n");}$file = $ARGV[0];$ip = "127.0.0.1";$port = 4444;$telnet = new Net::Telnet ( Port => $port, Timeout=>10, Errmode=>'die', Prompt =>'/>/');$telnet->open($ip);print $telnet->cmd('reset halt');print $telnet->cmd('flash probe 0');print $telnet->cmd('stm32f1x mass_erase 0');print $telnet->cmd('flash write_bank 0 '.$file.' 0');print $telnet->cmd('reset halt');print $telnet->cmd('exit');print "\n";
在根目录下的Makefile文件里面加入这段语句:
flash:all./do_flash.pl $(TOP)/main.bin
这样只要,执行make flash就可以直接运行第二步了,方便简介.
