Why does STM32CubeIDE add 96 bytes at address 0x20000000 to the firmware file when I compile?

[arnold_w]

I'm working with the STM32L4 Nucleo-64 Development Board and compiling with STM32CubeIDE 1.6.1. I have created a project using STM32CubeMX that I then imported into STM32CubeIDE. Hence, my linker script file was generated by STM32CubeIDE. Whenever I compile, my resulting (hex or binary) firmware file contains 96 bytes starting at address 0x20000000. Where do those bytes come from and what's the purpose of them?

Add NOLOAD.

blue_button_pin (NOLOAD) : ALIGN(4)
