Build Environment Setup
=======================
Retrieve required submodules to build this port. This might take a while for the first time:
Some variables must be exported into the environment prior to building this port.
Find more information at :ref:`env_vars` on how to keep this settings saved in you environment.
.. note::
In case of manual toolchain installation, set :file:`ESPRESSIF_TOOLCHAIN_PATH` accordingly.
Otherwise, set toolchain path as below. If necessary.
On Linux and macOS:
.. code-block:: console
export ZEPHYR_TOOLCHAIN_VARIANT="espressif"
export ESPRESSIF_TOOLCHAIN_PATH="${HOME}/.espressif/tools/riscv32-esp-elf/1.24.0.123_64eb9ff-8.4.0/riscv32-esp-elf"
export PATH=$PATH:$ESPRESSIF_TOOLCHAIN_PATH/bin
On Windows:
.. code-block:: console
# on CMD:
set ESPRESSIF_TOOLCHAIN_PATH=%USERPROFILE%\.espressif\tools\riscv32-esp-elf\1.24.0.123_64eb9ff-8.4.0\riscv32-esp-elf
set ZEPHYR_TOOLCHAIN_VARIANT=espressif
set PATH=%PATH%;%ESPRESSIF_TOOLCHAIN_PATH%\bin
# on PowerShell
$env:ESPRESSIF_TOOLCHAIN_PATH="$env:USERPROFILE\.espressif\tools\riscv32-esp-elf\1.24.0.123_64eb9ff-8.4.0\riscv32-esp-elf"
$env:ZEPHYR_TOOLCHAIN_VARIANT="espressif"
$env:Path += "$env:ESPRESSIF_TOOLCHAIN_PATH\bin"
Finally, retrieve required submodules to build this port. This might take a while for the first time:
