Install Prerequisites
|
|
=====================
|
|
|
|
To compile with ESP-IDF you need to get the following packages:
|
|
|
|
- CentOS 7::
|
|
|
|
sudo yum install gcc git wget make ncurses-devel flex bison gperf python python2-cryptography
|
|
|
|
- Ubuntu and Debian::
|
|
|
|
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 libffi-dev libssl-dev
|
|
|
|
- Arch::
|
|
|
|
sudo pacman -S --needed gcc git make ncurses flex bison gperf python-pyserial python-cryptography python-future python-pyparsing python-pyelftools
|
|
|
|
.. note::
|
|
|
|
Some older Linux distributions may be missing some of the Python packages listed above (or may use ``pyserial`` version 2.x which is not supported by ESP-IDF). It is possible to install these packages via ``pip`` instead - as described in section :ref:`get-started-get-packages-legacy`.
|
|
|
|
Toolchain Setup
|
|
===============
|
|
|
|
.. include:: /_build/inc/download-links.inc
|
|
|
|
ESP32 toolchain for Linux is available for download from Espressif website:
|
|
|
|
- for 64-bit Linux:
|
|
|
|
|download_link_linux64|
|
|
|
|
- for 32-bit Linux:
|
|
|
|
|download_link_linux32|
|
|
|
|
1. Download this file, then extract it in ``~/esp`` directory:
|
|
|
|
- for 64-bit Linux:
|
|
|
|
.. include:: /_build/inc/unpack-code-linux64.inc
|
|
|
|
- for 32-bit Linux:
|
|
|
|
.. include:: /_build/inc/unpack-code-linux32.inc
|
|
|
|
.. _setup-linux-toolchain-add-it-to-path-legacy:
|
|
|
|
2. The toolchain will be extracted into ``~/esp/xtensa-esp32-elf/`` directory.
|
|
|
|
To use it, you will need to update your ``PATH`` environment variable in ``~/.profile`` file. To make ``xtensa-esp32-elf`` available for all terminal sessions, add the following line to your ``~/.profile`` file::
|
|
|
|
export PATH="$HOME/esp/xtensa-esp32-elf/bin:$PATH"
|
|
|
|
Alternatively, you may create an alias for the above command. This way you can get the toolchain only when you need it. To do this, add different line to your ``~/.profile`` file::
|
|
|
|
alias get_esp32='export PATH="$HOME/esp/xtensa-esp32-elf/bin:$PATH"'
|
|
|
|
Then when you need the toolchain you can type ``get_esp32`` on the command line and the toolchain will be added to your ``PATH``.
|
|
|
|
.. note::
|
|
|
|
If you have ``/bin/bash`` set as login shell, and both ``.bash_profile`` and ``.profile`` exist, then update ``.bash_profile`` instead. In CentOS, ``alias`` should set in ``.bashrc``.
|
|
|
|
3. Log off and log in back to make the ``.profile`` changes effective. Run the following command to verify if ``PATH`` is correctly set::
|
|
|
|
printenv PATH
|
|
|
|
You are looking for similar result containing toolchain's path at the beginning of displayed string::
|
|
|
|
$ printenv PATH
|
|
/home/user-name/esp/xtensa-esp32-elf/bin:/home/user-name/bin:/home/user-name/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin
|
|
|
|
Instead of ``/home/user-name`` there should be a home path specific to your installation.
|
|
|
|
|
|
Permission issues /dev/ttyUSB0
|
|
------------------------------
|
|
|
|
With some Linux distributions you may get the ``Failed to open port /dev/ttyUSB0`` error message when flashing the ESP32. :ref:`This can be solved by adding the current user to the dialout group<linux-dialout-group-legacy>`.
|
|
|
|
|
|
Arch Linux Users
|
|
----------------
|
|
|
|
To run the precompiled gdb (xtensa-esp32-elf-gdb) in Arch Linux requires ncurses 5, but Arch uses ncurses 6.
|
|
|
|
Backwards compatibility libraries are available in AUR_ for native and lib32 configurations:
|
|
|
|
- https://aur.archlinux.org/packages/ncurses5-compat-libs/
|
|
- https://aur.archlinux.org/packages/lib32-ncurses5-compat-libs/
|
|
|
|
Before installing these packages you might need to add the author's public key to your keyring as described in the "Comments" section at the links above.
|
|
|
|
Alternatively, use crosstool-NG to compile a gdb that links against ncurses 6.
|
|
|
|
|
|
Next Steps
