Eclipse集成开发环境

1、集成开发环境

2、准备工作
从 sd/nor flash启动
格式化nand flash
 硬件连接：
1、Jlink连接
2、串口连接
3、nand启动
3、安装gdb server
tar xvzf arm-linux-gdb-7.5.tar.gz
./build-all
出错情况：configure: error: no termcap library found
make[1]: *** [configure-gdb] Error 1
make[1]: Leaving directory `/home/doctmp/part1/lesson1/ARM-tools/arm-linux-gdb-7.5/gdb-7.5'
make: *** [all] Error 2
最后在REHL的Package中找到了解决办法,安装ncurses-devel。
4、安装Jlink软件
tar xvzf JLink_Linux_V434a.tgz
cp -d libjlinkarm.sl* /usr/lib
cp 45-jlink.rules /etc/udev.rules.d/
 ./JLinkGDBServer 
5、安装eclipse
tar xvzf eclipse-cpp-helios-SR2-linux-gtk.tar.gz

出错提示：没有jdk或jre.Package包中找Open JDK安装

./eclipse >>help>>install newsoftware>>work with>>http://opensource.zylin.com/zylincdt>>add>next next finish(很漫长）

6、调试

导入led文件成为工程文件

project >>去掉Build Automatically
选择debug configurations
main:
gdb debugger选择arm-linux-gdb
commands:输入init2400文件
# connect to the J-Link gdb server
