ubuntu linux下建立stm32開發環境: 程序燒錄 openocd+openjtag


       上一篇博客寫了在ubuntu下,建立stm32開發環境,程序也已經編譯好生成main.bin,接下來就是要把該文件燒錄到stm32上.在linux下給arm燒錄程序主要使用openocd,這個軟件開源,而且支持眾多芯片,從ARM9到A8都可以,當然STM32也可以.支持的JTAG工具也很多,JLINK ST-LINK OSBDM都可以,我這正好有一個openjtag基於FT2232C的,也是被支持的.

一  安裝openocd

      在ubuntu下安裝openocd

      

sudo apt-get install openocd

      也可以到官網下載源碼包自己編譯


二 安裝openjtag驅動

      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+)

   第二個就是了,記下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"

   權限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 連openjtag

      JTAG接口配置文件openjtag.cfg.根據JTAG設備不同,修改下面

 

#interface configuration openjtag#############################
interface ft2232
ft2232_device_desc "USB<=>JTAG&RS232"
ft2232_layout jtagkey
ft2232_vid_pid 0x1457 0x5118

    可以參考openocd目錄下的文件:/usr/share/openocd/scripts/interface,主要是設備ID以及設備名字,可以通過dmesg | grep usb命令查看.
    要燒錄stm32f103就得有這個設備的相關配置,可以查看/usr/share/openocd/scripts/target/stm32f1x.cfg


 這里把兩個文件合在一起openocd.cfg

#daemon configuration###############################################################
telnet_port 4444
gdb_port 3333

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

開始燒錄:

  < 1 >  在一個終端下執行:

openocd -f openocd.cfg

沒有提示出錯,就表示連接上STM32了 .如果出現出錯,就在開發板上按下RESET 鍵復位,查看BOOT0和BOOT1有沒有設置出錯.


< 2 > 在另一個終端下,輸入:
       

telnet localhost 4444
依次輸入:

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

程序就燒好了,按下reset鍵,就開始運行了.

 要輸入這么多命令太麻煩了,寫個perl腳本使它一步運行.

首先安裝perl-telnet

    

sudo apt-get install libnet-telnet-perl

  在工程目錄下新建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";

   在根目錄下的Makefile文件里面加入這段語句:

flash:all
./do_flash.pl $(TOP)/main.bin

這樣只要,執行make flash就可以直接運行第二步了,方便簡介.
