(when building you can use, eg, `make PYTHON=python2` to specify the version
used). To install the required packages do:
```bash
$ pip install pyserial pyparsing
$ pip install pyserial 'pyparsing<2.4'
```
It is recommended to use a Python virtual environment if your system package
manager already provides these libraries, especially as the IDF v4.x is
currently incompatible with pyparsing 2.4 and higher.
Once everything is set up you should have a functioning toolchain with
prefix xtensa-esp32-elf- (or otherwise if you configured it differently)
as well as a copy of the ESP-IDF repository. You will need to update your `PATH`
