After powering up of Nucleo 144 board user LEDs start blinking after we press user push button. In which memory is this code loaded?

Hi! I am new to stm and recently started working on Nucleo 144 board. After powering on the board, the user LEDs start blinking in different frequencies after we press the push button. I wondered if this program is preloaded on flash?​

Yes, the ST Discovery and Nucleo use to come pre-loaded with a demo project - in Flash.

It is usually described on the website, and available in the firmware (or corresponding Cube/HAL) package.

Don't know the H7 specifically, though.
