Hi @felmue,
I believe it's the M5Stack Core. The sticker on the top reads 2AN3WM5Stack-CORE. It was purchased from here:
https://www.tinytronics.nl/shop/en/platforms-and-systems/m5stack/m5core/m5core/m5stack-esp32-basic-development-kit
My current sketch connects to my wifi, gets time via NTP and shows a little game of Pong on the screen. All of this works fine on the device.
The board selected in Arduino IDE is M5Stack-Core-ESP32
Hi @felmue,
Thanks for the response. This is the crash log:

When calling M5.Speaker.begin() I also get the IntegerDivideByZero.
I actually did not know there was a crash log like this, so thanks for that!
Burning the UIFlow firmware and using the speaker via https://flow.m5stack.com/ does work, so it must be something I am doing wrong. I am relieved that the device itself is not broken.
When I call the M5.Speaker.begin or M5.Speaker.tone functions it just crashes and reboots.
I'm coding from the Arduino IDE, and even the example Speaker sketch causes the same behaviour.
Is my M5Stack broken? I got the thing today, and I'm certain it was making sounds when it booted up the first time.
