1.2 Installation

1.2.1 Linux

• Installation tool chain

# 解压工具链到/opt目录下
sudo tar -xjf arm-2014.05-29-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2 -C /opt

# 将工具链添加进环境变量中
sudo vi /etc/bash.bashrc

# 在文件的最后一行将工具链添加进PATH变量中，如下所示
export PATH=$PATH:/opt/arm-2014.05/bin

# 使环境变量立即生效
source /etc/bash.bashrc

# 重新打开一个终端，在该终端中输入如下命令
arm-none-linux-gnueabi-gcc -v

# 如果有显示如下内容，则代表成功

• Maker soft link chain

The prefix of the tool chain is arm-none-linux-gnueabi-, this prefix to compile uboot, linuxand busyboxwhen there is no problem, but the gdbneed for arm-linux-such a prefix, it is necessary to make a soft link.
The following script file to make the link.

#!/bin/bash

ln -s arm-none-linux-gnueabi-addr2line arm-linux-addr2line

As shown below, enter the tool chain bindirectory, use vimto create makelink.sha script file, copy the contents of the above to a file, and execute it.

# 进入工具链路径
cd /opt/arm-2014.05/bin

# 创建脚本文件，并拷贝上述内容
sudo vi makelink.sh

# 改变脚本文件模式
sudo chmod 755 makelink.sh

# 执行脚本文件
sudo ./makelink.sh

# 验证
arm-linux-gcc -v

# 出现如下内容，则代表成功

• Compile gdb

Enter gdb-8.3.tar.gzthe directory where the file, execute the following command.

# 创建u-gdb目录
mkdir u-gdb

# 将gdb-8.3.tar.gz解压到u-gdb目录下
tar -xzf gdb-8.3.tar.gz -C ./u-gdb

New script file and put under u-gdb directory ( the file name is makegdbserver.sh ), copy the following to a file.

#!/bin/bash

# 进入gdb源码目录下
cd gdb-8.3

# 配置gdb
./configure --target=arm-linux --host=arm-linux CC=arm-linux-gcc

# 根据CPU个数进行编译
CPU_NUM=$(grep processor /proc/cpuinfo | awk '{field=$NF};END{print field+1}')

make -j$CPU_NUM

# 进入gdbserver目录
cd gdb/gdbserver/

# 删除上次生成的gdbserver文件
rm -f ../../../gdbserver

# 压缩gdbserver文件，去掉不必要的信息
arm-linux-strip gdbserver

# 拷贝gdbserver到u-gdb目录下
cp gdbserver ../../../

# 返回到gdb-8.3目录下
cd ..
cd ..

# 清除过程文件
make distclean

In u-gdb directory, using the following command to compile

./makegdbserver.sh

• Development copied to the target board gdbserver

Using FTP gdbserver copied to the target board development /usr/bindirectory, and using the following command to execute permissions change.

chmod 777 gdbserver
