Permission issues /dev/ttyUSB0

With some Linux distributions you may get the Failed to open port /dev/ttyUSB0 error

message when flashing the ESP32. This can be solved by adding the current user to the

dialout group.

Step 2. Get ESP-WHO

To build applications for the ESP32, you need the software libraries provided by

Espressif in ESP-WHO repository.

To get ESP-WHO, navigate to your installation directory and clone the repository

with git clone, following instructions below specific to your operating system.

Open Terminal, and run the following commands:

cd ~/esp

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

Step 3. Set up the Tools

Aside from the ESP-IDF, you also need to install the tools used by ESP-IDF, such as the

compiler, debugger, Python packages, etc.

ESP-IDF Tools Installer for Windows introduced in Step 1 installs all the required tools.

If you want to install the tools without the help of the ESP-IDF Tools Installer, open the

Command Prompt and follow these steps:

cd ~/esp/esp-idf

./install.sh
