Unable to program ESP32-WROVER-E

Postby joe_fang_iD » Tue Jan 09, 2024 1:53 am

Hello,

I'm trying to program a custom ESP32-WROVER-E using a ESP-PROG, and I'm receiving this issue when programming:

Code: Select all

Connecting......................................

A fatal error occurred: Failed to connect to ESP32: Wrong boot mode detected (0x12)! The chip needs to be in download mode.
For troubleshooting steps visit: https://github.com/espressif/esptool#troubleshooting
CMake Error at run_serial_tool.cmake:56 (message):

  C:/Espressif/frameworks/esp-idf-v4.4/components/esptool_py/esptool/esptool.py
  --chip esp32 failed
when I monitor the board, I receive:

Code: Select all

Check your bootstrap pins. At the very least, GPIO0 should be low. Could be that you need to look at the ESP-PROG jumpers if that is connected to GPIO0.
