Building ESP32 IDF on Ubuntu Linux

1. Get the tools:
   

   sudo apt-get install git wget flex bison gperf python3 python3-pip python3-venv cmake ninja-build ccache libffi-dev libssl-dev dfu-util libusb-1.0-0 minicom

2. Create the ESP32 IDF diretory:
   

   mkdir -p ~/esp

3. Get the ESP32 IDF:
   

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

4. Install the IDF:
   

   cd ~/esp/esp-idf
   ./install.sh all

5. Export the IDF symbols:
   

   . ./export.sh

6. Add the following to ~/.bashrc:
   

   alias get_idf='. $HOME/esp/esp-idf/export.sh'

7. Create ~/esp/flash.sh with the following lines:
   

   idf.py -p /dev/ttyUSB0 flash
   sudo minicom -b 115200 -8 -D /dev/ttyUSB0 < /dev/tty

8. Enable execution of flash.sh
   

   chmod +x ~/etc/flash.sh

9. Build Hello World:
   

   cd ~/esp
   cp -r $IDF_PATH/examples/get-started/hello_world .
   cd ~/esp/hello_world
   idf.py set-target esp32
   idf.py menuconfig
   idf.py build

10. Download Hello World into Flash:
    

    ~/esp/flash.sh
