Bill,
I am running Debian 12 and last week installed Arduino IDE 1.8.19.
Followed the same instructions as above with no issues, it only took more time then then mentions ‘ few seconds’. A lot of dependent packages were installed, took over several minutes.
Make sure the Arduino IDE has internet access (proxy?)
After step 2 in ‘Installing the ESP32 in Arduino IDE’, close the program and restart it, to see if it is set correctly in Preferences.
Then step 3. Open the Boards Manager. Go to Tools > Board >Boards Manager…
I installed ‘ESPEssentials’ instead of the mentioned ESP32, as I wanted to test a WROOM version of ESP, and this worked fine.
Weird issue I face is: only the first compile works, a second, third etc run will always fail (although I run the IDE inside it’s own python virtual environment).

Followed the instructions above to add the esp32 board to Arduino IDE (1.8.19), but no entry exists in the Library Manager. MANY esp32-related entries, but not the one you show in the tutorial.

Thanks for this tutorial, it’s clear, simple and correct.
I’m on Debian 12 “bookworm” where the whole install command is:

sudo apt update && sudo apt install -y python3-serial arduino

My generic ESP-VROOM-32 board worked out of the box.

A serial exception error occurred: Write timeout
Note: This error originates from pySerial. It is likely not a problem with esptool, but with the hardware connection or drivers.

Hello Sara!

My problem is a bit more complicated but I found a solution:
https://www.studiopieters.nl/esp32-s2/

The other problem is that there is some strange behaviour using Arduino IDE. When I compile a Sketch for ESP32 using OneWire library compiler terminates with error message:

c:\Users\penat\Documents\Arduino\libraries\OneWire\util/OneWire_direct_gpio.h:134:17: error: ‘GPIO’ was not declared in this scope

but same Sketch compiles ok if board is ESP8266. The Sketch I am using is OneWire example Sketch. Any idea about reason?

Hi.
I’m not sure. Try to press the RST button on your board when you’re uploading new code.

Sara

Hi Sara!
I am trying to program ESP32-S2 board using Arduino IDE. Scetch loads but finally there is some problem in order to run it:

WARNING: ESP32-S2FNR2 (revision v1.0) chip was placed into download mode using GPIO0.
esptool.py can not exit the download mode over USB. To run the app, reset the chip manually.
To suppress this note, set –after option to ‘no_reset’.

Any idea how to solve this?

When trying to upload my code to a ESP32 DEVKIT V1 – DOIT board, I get the error msg: Wrong boot mode detected (0X13), visit: https://docs.espressif.com/projects/esptool/en/latest/troubleshooting.html.

Please help.

Thanks
