创建M6708核心板编译环境

         linux嵌入式arm板为周立功的M6708U-1GLI-T核心板。

一、Ubuntu

下载ubuntu 18.04.6 64位

http://releases.ubuntu.com/18.04.6/ubuntu-18.04.6-desktop-amd64.iso

二、应用编译：

1. 安装编译环境

工具链：poky-glibc-x86_64-meta-toolchain-cortexa9hf-vfp-neon-toolchain-1.7.tar.gz

解压至/opt/路径，解压后路径如：/opt/poky/1.7/

2. 设置环境变量

source /opt/poky/1.7/environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi

3. 编译

   a) 如果编译提示：

berryz2007@ubuntu:~/gpio/gpio_test$ make

Fatal Python error: Py_Initialize: Unable to get the locale encoding

ModuleNotFoundError: No module named 'encodings'

Current thread 0x00007f547f226740 (most recent call first):

Aborted (core dumped)

    则：安装make

berryz2007@ubuntu:~/gpio/gpio_test$ sudo apt-get install make

三、内核编译

a) sudo apt-get install lzop

        b) 添加阿里云源

            sudo vi /etc/apt/sources.list

            deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse

            deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse

            deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse

            deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse

            deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse

            deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse

            deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse

            deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse

            deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

            deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

        更新源

            sudo apt-get update

        安装gcc

             sudo apt-get install gcc

        编译内核

             ./build.sh
