海思GDB8.3 + GDB Server调试
1、下载
下载地址：http://ftp.gnu.org/gnu/gdb/
镜像站点：https://mirrors.ustc.edu.cn/gnu/
2、解压并创建目录
tar -zxvf gdb-8.3.tar.gz
mkdir obj_gdb
mkdir obj_gdbserver
touch ./obj_gdb/build
touch ./obj_gdbserver/build
3、前期准备
8.0以后要依赖expat库，不装的话会运行时会出现如下错误：
(gdb) target remote 192.168.0.138:1234
Remote debugging using 192.168.0.138:1234

linux下下载expat库：git clone https://github.com/libexpat/libexpat.git (网址：https://github.com/libexpat/libexpat)
得到libexpat
cd libexpat/expat
./buildconf.sh
#（如果出错./autogen.sh: autoreconf: not found，按照网址https://blog.****.net/mybelief321/article/details/9208073添加#autoreconf等工具
./configure --without-docbook --prefix=/usr/local/arm-gdb/expat_out
make & make install
4、编译
#GDB编译
cd obj_gdb
vi build
#填写以下内容
../gdb-8.3/configure --target=arm-hisiv600-linux --prefix=/home/lzl/1-tools/obj_gdb/install --with-expat --with-libexpat-prefix=/usr/local/arm-gdb/expat_out
make
make install
#GDB Server编译
cd obj_gdbserver
vi build
#填写以下内容
./gdb-8.3/gdb/gdbserver/configure --target=arm-hisiv600-linux --host=arm-hisiv600-linux make CC=arm-hisiv600-linux-gcc
5、调试
#方法1：
板子运行：
./gdbserver 192.168.2.190:1234 test
虚拟机运行：
./arm-hisiv600-linux-gdb
(gdb) target remote 10.0.12.143:1234
(gdb) c
#方法2：
使用core文件

运行方式： ./arm-hisiv600-linux-gdb （运行文件） （core文件）
