操作系统:VMware fusion + Ubuntu 16.04.1 LTS
开发板:JZ2440 V3 + EasyOpenJTAG

Ubuntu 16.04下EasyOpenJTAG+OpenOCD的安装和使用【转】-LMLPHP
 
要烧写裸机程序离不开OpenJTAG,OpenJTAG包含了3大功能,USB 转串口、USB 转 JTAG、 在线调试。
借助OpenOCD等开源软件可以完成程序的下载、烧写、调试等任务:
首先安装libftdi和ftdi-eeprom 下载地址http://www.intra2net.com/en/developer/libftdi/download.php:
 
1、下载confuse-2.5.tar.gz  libftdi1-1.3.tar.bz2并解压:
root@ubuntu:/work/tmp# ls /mnt/hgfs/jz2440/download/  
confuse-2.5.tar.gz  libftdi1-1.3.tar.bz2 
root@ubuntu:/work/tmp# tar -jxvf /mnt/hgfs/jz2440/download/libftdi1-1.3.tar.bz2 -C ./  
root@ubuntu:/work/tmp# tar -zxvf /mnt/hgfs/jz2440/download/confuse-2.5.tar.gz -C ./  
 
2、安装libftdi,参考源码目录下的README.build:
root@ubuntu:/work/tmp/libftdi1-1.3# mkdir build; cd build:  
root@ubuntu:/work/tmp/libftdi1-1.3# cmake  -DCMAKE_INSTALL_PREFIX="/usr" ../; make; sudo make install  
 
3、安装ftdi-eeprom,参考源码目录下的INSTALL
root@ubuntu:/work/tmp# cd confuse-2.5/; ./configure; make; make install
 
然后安装OpenOCD
1]、下载OpenOCD
root@ubuntu:/work/tmp# git clone git://openocd.git.sourceforge.net/gitroot/openocd/openocd 
 
2]、编译并安装, 请参考源码目录下的README.build
root@ubuntu:/work/tmp/openocd# ./bootstrap  
root@ubuntu:/work/tmp/openocd# ./configure --enable-ftdi  
root@ubuntu:/work/tmp/openocd# make; make install  
编译后的版本为:
root@ubuntu:/work/tmp/openocd# openocd -v

3]、增加udev规则,以便使用普通用户权限操作调试器。以root权限创建/etc/udev/rules.d/45-openjtag.rules(文件名可以换成别的):
SYSFS{idProduct}=="5118", SYSFS{idVendor}=="1457", MODE="666", GROUP="plugdev"
 
4]、添加OpenOCD配置文件openocd.cfg:
interface ftdi  
#通过描述来指定设备,应当和dmesg中的Product一致  
#ftdi_device_desc "USB<=>JTAG&RS232"  
#通过PID VID指定调试器,比描述更准确些  
ftdi_vid_pid 0x1457 0x5118  
#如果有多个同样的调试器,还可以指定要使用的调试器序列号  
#ftdi_serial  
#引脚定义,相当于旧版中的 ft2232_layout jtagkey  
ftdi_layout_init 0x0c08 0x0f1b  
ftdi_layout_signal nTRST -data 0x0100 -noe 0x0400  
ftdi_layout_signal nSRST -data 0x0200 -noe 0x0800

set  _CHIPNAME $CHIPNAME  
} else {

}
if { [info exists ENDIAN] } {  
set  _ENDIAN $ENDIAN  
} else {

set  _ENDIAN little  
}
if { [info exists CPUTAPID ] } {  
set _CPUTAPID $CPUTAPID

最后启动OpenOCD:首先将EasyOpenJTAG USB连接至PC,然后开发板上电,最后在和配置文件openocd.cfg相同目录执行openocd
