Being in terminal window, go to directory of hello_world application by typing cd󰲧~/esp/

hello_world. Then start project conﬁguration utility menuconfig:

cd󰲧~/esp/hello_world

make󰲧menuconfig

If previous steps have been done correctly, the following menu will be displayed:

In the menu, navigate to Serial flasher config > Default serial port to conﬁgure the serial

port, where project will be loaded to. Conﬁrm selection by pressing enter, save

conﬁguration by selecting < Save > and then exit application by selecting < Exit >.

Here are couple of tips on navigation and use of menuconfig:

• Use up & down arrow keys to navigate the menu.

•

Use Enter key to go into a submenu, Escape key to go out or to exit.

• Type ? to see a help screen. Enter key exits the help screen.

• Use Space key, or Y and N keys to enable (Yes) and disable (No) conﬁguration items

with checkboxes “[*]“.

• Pressing ? while highlighting a conﬁguration item displays help about that item.

• Type / to search the conﬁguration items.

📖 Notes:

• On Windows, serial ports have names like COM1. On MacOS, they start with /dev/cu.. On Linux, they

start with /dev/tty. (See :doc:`establish-serial-connection` for full details.)

•

If you are Arch Linux user, navigate to SDK tool configuration and change the name of Python 2

interpreter from python to python2.

• Most ESP32 development boards have a 40 MHz crystal installed. However, some boards use a 26 MHz

crystal. If your board uses a 26MHz crystal, or you get garbage output from serial port after code upload,

adjust the :ref:`CONFIG_ESP32_XTAL_FREQ_SEL` option in menuconfig.
