ubuntu下建立stm32开发环境:程序烧录openocd+openjtag

上一篇博客写了在ubuntu下,建立stm32开发环境,程序也已经编译好生成main.bin,接下来就是要把该文件烧录到stm32上.在Linux下给arm烧录程序主要使用openocd,这个软件开源,而且支持众多芯片,从ARM9到A8都可以,当然STM32也可以.支持的JTAG工具也很多,JLINK ST-LINK OSBDM都可以,我这正好有一个openjtag基于FT2232C的,也是被支持的.

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：http://www.embbnux.com

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:~/$ lsusb 
Bus 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 ft2232 
ft2232_device_desc "USB<=>JTAG&RS232" 
ft2232_layout jtagkey 
ft2232_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

#daemon configuration###############################################################

开始烧录:

  < 1 >  在一个终端下执行:
            openocd -f openocd.cfg

出现:

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 halt 
       flash probe 0 
       stm32f1x mass_erase 0 
       flash write_bank 0 /you_stm32_project_dir/main.bin 0 
       reset 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/perl 
use 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.
