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

之前建立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.

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###############################################################
telnet_port 4444
gdb_port 3333

#interface configuration openjtag#############################

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.
