Espressif ESP32-S2 User Manual

Chapter 1. Get Started
• CentOS 7 & 8:
sudo yum -y update && sudo yum install git wget flex bison gperf python3␣
,→python3-pip python3-setuptools cmake ninja-build ccache dfu-util libusbx
CentOS 7 is still supported but CentOS version 8 is recommended for a better user experience.
• Arch:
sudo pacman -S --needed gcc git make flex bison gperf python-pip cmake ninja␣
,→ccache dfu-util libusb
Note:
• CMake version 3.5 or newer is required for use with ESP-IDF. Older Linux distributions may require updating,
enabling of a “backports”repository, or installing of a “cmake3”package rather than “cmake”.
• If you do not see your Linux distribution in the above list then please check its documentation to find out which
command to use for package installation.
Additional Tips
Permission issues /dev/ttyUSB0 With some Linux distributions you may get the Failed to open port
/dev/ttyUSB0 error message when flashing the ESP32-S2. This can be solved by adding the current user to the
dialout group.
Python compatibility
ESP-IDF supports Python 3.6 or newer. It is recommended to upgrade your operating system to a recent version
satisfying this requirement. Other options include the installation of Python from sources or the use of a Python
version management system such as pyenv.
Next Steps
To carry on with development environment setup, proceed to Step 2. Get ESP-IDF.
