Ursache:
Wenn der PIN EN auf GRD verbunden ist oder GPIO0 G0 auf 3,3 Verbunden ist
Verhalten:
Beim Upload eines neuen Programms Sketch bleibt der Upload-Vorgang hängen mit der Meldung
Connecting........_____....._____....._____....._____....._____....._____.....____An error occurred while uploading the sketch
|
Lösung:
Entweder mit einem kleinen Kondensator oder einem Pullup Widerstand auf das andere Level ziehen
Im Serial Monitor
Sketch uses 211501 bytes (16%) of program storage space. Maximum is 1310720 bytes. Global variables use 15428 bytes (4%) of dynamic memory, leaving 312252 bytes for local variables. Maximum is 327680 bytes. esptool.py v2.6 Serial port COM3 Connecting........_____....._____....._____....._____....._____....._____.....____An error occurred while uploading the sketch _
A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header |
Nach dem Lösen der Verbindungen wird das Programm normal hochgeladen zu ESP32 node MCU (ESP32 WROOM32 )
