韦东山-qemu环境搭建

一、python优先级调节

调整Python3的优先级，使得3.6优先级较高

sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.5 1

sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 2

更改默认值，python默认为Python2，现在修改为Python3

sudo update-alternatives --install /usr/bin/python python /usr/bin/python2 100

sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 150

二、ubuntu18.04

1、坏境搭建

wget --no-check-certificate -O Configuring_ubuntu.sh ​​https://weidongshan.coding.net/p/DevelopmentEnvConf/d/DevelopmentEnvConf/git/raw/master/Configuring_ubuntu.sh​​ && sudo chmod +x Configuring_ubuntu.sh && sudo ./Configuring_ubuntu.sh

sudo apt-get install git curl libsdl2-mixer-2.0-0 libsdl2-image-2.0-0 libsdl2-2.0-0

git config --global user.email "[e-mail]"

git config --global user.name "jiangfeng.zhang"

2、下载源码

sudo ../repo/repo init -u ​​https://e.coding.net/weidongshan/manifests.git​​ -b linux-sdk -m imx6ull/100ask-imx6ull_qemu_release_v1.0.xml --no-repo-verify

sudo ../repo/repo sync -j4

3、下载qemu

git clone ​​https://e.coding.net/weidongshan/ubuntu-18.04_imx6ul_qemu_system.git​​

4、编译内核镜像

PATH=$PATH:/home/book/100ask_imx6ull-qemu/ToolChain/gcc-linaro-6.2.1-2016.11-x86_64_arm-linux-gnueabihf/bin

make mrproper

make 100ask_imx6ull_qemu_defconfig

make zImage -jN

make dtbs
