What could be causing the constant restarts when using the Arduino IDE?

The board do not make restarts and run simple examples unde ESP-IDF environment.

From four requirements:

  • USB Mode: Hardware CDC and JTAG
  • USB CDC on Boot: Enabled
  • Upload Mode: UART0 / Hardware CDC
  • PSRAM: QSPI PSRAM

Only the last one is not fulfilled. In my environment PSRAM is set to OPI PSRAM, otherwise I have compilation error. See dedicated discussion
