Eclipse集成開發環境安裝及調試

準備工作-1

從/nor flash啓動，格式化nand flash。

準備工作-2

1. Jlink鏈接
2. 串口連接
3. nand flash啓動

安裝gdb server

cd /home/s3-arm/part1/lesson1/ARM-tools/
tar xvzf arm-linux-gdb-7.5.tgz
cd ./arm-linux-gdb-7.5
./build all

配置環境變量

vim /root/.bashrc

# .bashrc

# User specific aliases and functions

alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'
# Source global definitions
if [ -f /etc/bashrc ]; then
        . /etc/bashrc
fi

export PATH=$PATH:/opt/arm-linux-gdb/bin/
export PATH=$PATH:/usr/local/arm/4.3.2/bin/

安裝Jlink軟件

cd /home/s3-arm/part1/lesson1/ARM-tools/
tar xvzf Jlink_Linux_V434a.tgz
cd Jlink_Linux_V434a
cp -d libjlinkarm.so* /usr/lib -f
cp 45-jlink.rules /etc/udev/rules.d/

安裝Eclipse

redhat6已經有安裝了eclipse，但版本不對。

[root@localhost JLink_Linux_V434a]# which eclipse
/usr/bin/eclipse

註銷版本不對的eclipse

cd /etc/bin/
mv ./eclipse ./eclipse_backup

安裝ARM-tools中的eclipse

cd /home/s3-arm/part1/lesson1/ARM-tools/
tar xvzf eclipse-cpp-helios-SR2-linux-gtk.tar.gz
cd ./eclipse
./eclipse

安裝插件

爲了能讓eclipse和armJlink協同工作，需要安裝插件

Work with:http://opensource.zylin.com/zylincdt
Next–>Next–>Finish–>Restart Now
到這裏eclipse已安裝好

使用eclipse建立裸機代碼工程並配置調試

首先拷貝這3個文件

打開eclipse

File---->New---->Makefile Projict with Existing Code

找到代碼位置，確定，Finish

去掉自動編譯

選擇工程右鍵，Build Project

配置調試

把代碼粘貼到下面

Apply---->Close，一切就緒

啓動調試

特別提醒

啓動eclipse之前請先啓動JlinkGDBServer
