If IDF monitor fails shortly after the upload, or, if instead of the messages above, you see random garbage similar to what is given below, your board is likely using a 26 MHz crystal. Most development board designs use 40 MHz, so ESP-IDF uses this frequency as a default value.

If you have such a problem, do the following:
1. Exit the monitor.
- 2. Go back to `menuconfig`.
- 3. Go to Component config --> ESP32-specific --> Main XTAL frequency, then change :ref:`CONFIG_ESP32_XTAL_FREQ_SEL` to 26 MHz.
