strip.show(); crashes Arduino Nano ESP32 with Espressif ESP32 3.0.4 board #401

Choose the Arduino Nano ESP32 from the Espressif esp32 board. Partition Scheme: With FAT Pin Numbering: By GPIO number (legacy)

Open examples-> Adafruit->RGBW strandtest Compile and upload The Nano ESP32 will crash immediately.

In my own program, that uses this library, the crash follows when using the strip.show(); command. The program starts up and runs well until the strip.show(); command is used and the MCU reboots.

NOTE: When the Arduino ESP32 board is used the strip.show(); command works well.

Me too, using Arduino IDE v1.8.19 & ESP32 Dev Module with Board Manager v3.0.4. Once strip.show(); is called the ESP32 reboot with error messages below. The same code compiled with Board Manager v2.0.17 without any problems.

I wrote a library for the SK6812 and WS2812 LEDs
