ESP32 Forum

MacOS 10.15.7, Arduino 1.8.19. Adafruit ESP32 Huzzah.
My IDE was working and then suddenly stopped uploading to the ESP32 board with error:
java.io.IOException: Cannot run program "___REMOVE___/esptool": error=2, No such file or directory
I changed to the Arduino IDE 2.0.4 and it works fine there.
The directory ~/Library/Arduino15/packages/esp32/tools/esptool_py/4.5 has esptool in it but the 1.8.19 IDE can no longer find it.
I would like to use the legacy IDE. What to do?

I found the fix on the Arduino forum:
See https://github.com/espressif/arduino-esp32/issues/7923
The workaround fixed the 1.8.19 IDE upload problem and the tools/ESP32 Sketch Data Upload problem both related to not finding esptool.
Arduino's IDE 2.0.4 does not support Sketch Data Upload so to do that you need to use IDE 1.xx.

Well, how to deal with such a problem? I don't know anymore

Hello,

Does the problem go away when you close de IDE and re-open?

I found the solution on the Arduino site. Apparently the lastest version of esptool was not supported by the version the ESP32 core. I deleted the core and reinstalled it and now everything works again.
