新建用户名和密码

更改软件源

备份

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

修改

sudo vim /etc/apt/sources.list

将原有源注释或删除，添加以下源：

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-backports main restricted universe multiverse

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

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

更新源

sudo apt-get update
sudo apt-get upgrade

设置ESP-IDF工具链

安装编译所需要的依赖库

sudo apt-get install gcc git wget make libncurses-dev flex bison gperf python python-pip python-setuptools python-serial python-cryptography python-future python-pyparsing python-pyelftools

获取工具链

wget https://dl.espressif.com/dl/xtensa-esp32-elf-linux64-1.22.0-80-g6c4433a-5.2.0.tar.gz

解压

mkdir -p ~/esp
cd ~/esp
tar -xzf ~/Downloads/xtensa-esp32-elf-linux64-1.22.0-80-g6c4433a-5.2.0.tar.gz

添加工具链到环境变量

vim ~/.profile

添加

export PATH="$HOME/esp/xtensa-esp32-elf/bin:$PATH"

更新环境变量

source ~/.profile

获取ESP-IDF

cd esp
git clone --recursive https://github.com/espressif/esp-idf.git

注意千万不要少了–recursive参数，否则无法获取子模块代码。
将IDF添加到环境变量

vim ~/.profile
export IDF_PATH="$HOME/esp/esp-idf"

编译ESP-IDF

安装python库

python2.7 -m pip install --user -r $IDF_PATH/requirements.txt

复制Demo工程

cp -r $IDF_PATH/examples/get-started/hello_world .  

配置串口

make menuconfig

编译

make

烧录

make flash

烧录时，出现以下信息时，需要按下BOOT按键，然后按RESET按键。

查看监视器

make monitor
