ESP32 S3 DevKit problems

Other Hardware 3rd Party Boards
1

I am trying to get the ESP32 S3 DevKitC1 running in the Arduino IDE (version 2.10)

I have installed the latest ESP32 board manager (version 2.09)

The normal Blink sketch seems to upload fine. At the end of the upload I get the "Hard resetting via RTS pin..." message but then nothing happens

I have tried another blink sktech for the S3 that blinks all three onboard LEDs but still nothing happens

I have read other posts suggesting you need to change the Flash PSRAM modes. I have tried the suggestions but still no success

Does anyone have experience of getting this board to run under Arduino IDE?

Thanks

I had no problem with the Arduino IDE 1.8.19 version. I don't use any of the IDE v2.x versions ,so I don't know if they have problems.

After uploading to an S3 board the board must be power cycled to make it
run the code that was just uploaded. I now use the S3 connected to a USB hub with a
power button for each port. Using the power button is much easier than
unplugging and plugging the USB cable. IDE 1.8.19.

Turns out I was being silly. The ESP32 S3 DevKitC1 only has RGB LED on GPIO 48 so the normal blink example won't work.

I downloaded a Hello World message to serial console and it worked fine so download is working

Thanks

There is a BlinkRGB under the ESP32->GPIO examples that uses the onboard RGB LED.

Oh thank you @ oldcurmudgeon for the hint, I had the same problem with my board's ( ESP32 S3 DevKitC1 clone) RGB led, and was looking for a simple way to turn it on and choose the colour (simple way >> no need to load a library like Adafruit Neopixel).
It works like a charm !
