准备工作-1

从/nor flash启动，格式化nand flash。

准备工作-2

1. Jlink链接
2. 串口连接
3. nand flash启动

安装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

配置环境变量

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/

安装Jlink软件

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/

安装Eclipse

redhat6已经有安装了eclipse，但版本不对。

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

注销版本不对的eclipse

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

安装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

安装插件

为了能让eclipse和armJlink协同工作，需要安装插件

Work with:http://opensource.zylin.com/zylincdt
Next–>Next–>Finish–>Restart Now
到这里eclipse已安装好

使用eclipse建立裸机代码工程并配置调试

首先拷贝这3个文件

打开eclipse

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

找到代码位置，确定，Finish

去掉自动编译

选择工程右键，Build Project

配置调试

把代码粘贴到下面

target remote localhost:2331
# Set JTAG speed to 30 kHz
monitor endian little
monitor speed 30
# Reset the target
monitor reset

Apply---->Close，一切就绪

启动调试

特别提醒

启动eclipse之前请先启动JlinkGDBServer
