ESP32-S3 Core Board - Resetting when Connecting/Disconnecting USB Serial Cable - egionet - 05-16-2025

Has anyone else experienced the following behaviour with the ESP32-S3 Core Board:
  1. Connect the ESP32-S3 Core Board to the development PC via a USB serial cable.
  2. Compile the program and upload the binary to the ESP32-S3 Core Board.
  3. Observation #1: If the development PC is left connected for 2 to 3 hours, the ESP32-S3 Core Board reboots or it goes into an inoperable state that requires a hard reset.
  4. Observation #2: If the USB serial port's connection is cycled, from connected to disconnected, and then reconnected a couple of times, the ESP32-S3 Core Board reboots.
  5. Observation #3: If the USB serial cable is disconnected, the ESP32-S3 Core Board operates flawlessly.  The ESP32-S3 Core Board was left powered for a 7-day burn-in with no reboots or memory leaks.

Thanks in advance.

do you use your own arduino code?

I use PlatformIO and the esp-idf framework (espressif32 platform).  This behaviour occurs when a basic program is uploaded, and it doesn't happen when I upload the same code to a standard 44-pin ESP32-S3 WROOM development board.

maybe you can send me one BIN file, we can download to ESP32S3, power on ,test for somedays, check whether will reboot.

I plan to buy another ESP32-S3 Core Board for another device I am working on.  My existing ESP32-S3 Core Board is in use and not easily accessible for conducting tests.  Once I have another board, I will be able to run more tests.  If Kincony would like to donate one, it would be greatly appreciated.
