I purchased a new ESP32-S3 board from Aliexpress. The product page does not say which board to select in the Arduino IDE to program it. I tried several, including ESP32 Dev Module. I selected the 16MB memory option and enabled PSRAM. I get this error regardless of which board or options that I choose:

Code: Select all

I have programmed other ESP32 boards such as the Adafruit feather and Lolin D32 Pro successfully, but I can't program this one. Here is the link on AliExpress:

Could you tell me the right options to program it?

You have selected a board that uses an ESP32, which is a different chip than the ESP32-S3. Select an ESP32-S3 board instead.

If your device is a ESP32-S3-WROOM-2 (aka octal flash), there is a separate entry for that as well.

Thanks for the help. I followed the instructions at: https://docs.espressif.com/projects/ard ... stallation and everything seemed to go as expected. However, when I attempt to compile in Arduino IDE 1.8.19 (latest) after choosing "ESP32S3 Dev Module" board or a few other boards I get this error:

Error compiling for board ESP32S3 Dev Module:
The system cannot find the path specified.
exit status 1
Error compiling for board ESP32S3 Dev Module.

Do you know how this can be fixed? I suspect it is possible there is confusion about exactly where is the "sketchbook directory". In my Arduino preferences menu it lists "C:\Users\perigalacticon\OneDrive\Documents\Arduino" as the sketchbook location that I have been using which has worked consistently for all other boards. There was not a "hardware" folder in the listed sketchbook location before I installed the latest espressif folder; however I have been compiling for other ESP32 and ESP8266 boards so I'm not sure what espressif folder the compiler had been using before I installed this latest one.

The path to the newly installed folder is: C:\Users\perigalacticon\OneDrive\Documents\Arduino\hardware\espressif\esp32

Don't use OneDrive with a manual installation.
Make sure to run get.exe after doing a git pull.
Why are you doing a manual installation? Use the board manager.

Thanks for the advice. OneDrive did cause me trouble once before but not recently. I did a manual installation because I used information from Adafruit's guide for their ESP32S3 Feather. It said to use manual installation to get the most recent boards setup because I guess at the time it wasn't included in the std Arduino boards manager.

I fixed it however, and now everything works as expected. This is what I did, FYI for anyone that ever runs into this (prob no one): I removed the "hardware" directory from the Arduino sketch folder. Then I went to boards manager but I couldn't install it that way because it said already installed at the latest version, so I first installed the next highest version, and then the board programmed as expected. Then I updated to the latest version again using the boards manager. Thanks for the help, this will be the brain of my new robot!
