The toolchain will be extracted into ~/esp/xtensa-esp32-elf/ directory.
To use it, you will need to update your ``PATH`` environment variable in ~/.bash_profile file.
To make xtensa-esp32-elf` available for all terminal sessions, add the following line to your
~/.bash_profile file:
export󰲧PATH=$PATH:$HOME/esp/xtensa-esp32-elf/bin
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 ~/.bash_profile file:
