or monitor fails shortly after upload, your board is likely using 26MHz crystal, while the ESP-IDF assumes default of 40MHz. Exit the monitor, go back to the :ref:`menuconfig <get-started-configure>`, change :ref:`CONFIG_ESP32_XTAL_FREQ_SEL` to 26MHz, then :ref:`build and flash <get-started-build-flash>` the application again.

This is found under ``make menuconfig`` under Component config --> ESP32-specific --> Main XTAL frequency.
To execute ``make flash`` and ``make monitor`` in one go, type ``make flash monitor``. Check section :doc:`IDF Monitor <idf-monitor>` for handy shortcuts and more details on using this application.
