FAQ

1. What will cause burning error?

• There is no delay or too short delay in Loop.

• The USB cannot be recognized by the PC as some functions are incorrectlly called.

How to solve

• Press and hold BOOT, click RST, and then release the BOOT button to burn.

Principle During the initialization process, ESP32 undertakes a verification of the voltage level on the BOOT (IO9) pin. If the voltage level is determined to be high, the system proceeds with a normal startup. In contrast, if the voltage level is deemed to be low, the device enters into the programming mode. By default, the BOOT pin maintains a high voltage level, but it transitions to a low level when a button is pressed.

2. Data cannot be printed on serial port

• Check if the USB CDC is enabled
• Check print information using other serial debugger.
