pyocd调试ARM芯片，Ubuntu 安装arm-none-eabi-gdb

目的

在linux下面安装arm交叉编译工具，实现下载、调试

下载安装包

如果用sudo apt-get remove gcc-arm-none-eabi 安装的交交叉编程工具，是没有含GDB工具的，所以需要卸载后才能安装。

sudo apt-get remove gcc-arm-none-eabi就可以完成卸载，如果还有在/usr/bin/arm-none-eabi-下面的文件有冲突的，先要删除才能安装成功。

安装包下载网址：Downloads | GNU Arm Embedded Toolchain Downloads – Arm Developer

我的虚拟机是x86的，所以下载以下文件。下载速度很慢的，可以复制链接，用下载工具下载。

安装

我试着按其人的安装教程，想把文件解压到/usr/share/目录下，但是好象不能成功。我所以在/opt/下面新建了gdb文件夹，并修改权限。

然后解压到这个文件夹下面：

tar -jxvf gcc-arm-none-eabi-10.3-2021.10-x86_64-linux.tar.bz2 -C /opt/gdb/

最后创建软件连接到/usr/bin/目录下面：

sudo ln -s /opt/gdb/gcc-arm-none-eabi-10.3-2021.10/bin/arm-none-eabi-objcopy /usr/bin/arm-none-eabi-objcopy
sudo ln -s /opt/gdb/gcc-arm-none-eabi-10.3-2021.10/bin/arm-none-eabi-objdump /usr/bin/arm-none-eabi-objdump 
sudo ln -s /opt/gdb/gcc-arm-none-eabi-10.3-2021.10/bin/arm-none-eabi-gcc /usr/bin/arm-none-eabi-gcc
sudo ln -s /opt/gdb/gcc-arm-none-eabi-10.3-2021.10/bin/arm-none-eabi-g++ /usr/bin/arm-none-eabi-g++
sudo ln -s /opt/gdb/gcc-arm-none-eabi-10.3-2021.10/bin/arm-none-eabi-gdb /usr/bin/arm-none-eabi-gdb
sudo ln -s /opt/gdb/gcc-arm-none-eabi-10.3-2021.10/bin/arm-none-eabi-szie /usr/bin/arm-none-eabi-size
sudo ln -s /opt/gdb/gcc-arm-none-eabi-10.3-2021.10/bin/arm-none-eabi-as /usr/bin/arm-none-eabi-as

    ]
}

总结

我前面因为gdb没有安装成功，后面去下载源码进行编译，花了很长的时间，最后在Downloads | GNU Arm Embedded Toolchain Downloads – Arm Developer下载包进行直接解压，快速方便。
