Bare metal programming is writing firmware which directly runs on the hardware without having any underlying abstraction such as operating systems. Generally bare metal programs will have minimal bootloader to initiate the processor,clock and memory and jump to main program.

Why is it called bare metal?

The term bare metal refers to the fact that there is no operating system between the virtualization software and the hardware. The virtualization software resides on the “bare metal” or the hard disk of the hardware, where the operating system is usually installed. Bare metal isn’t only used to describe hypervisors.

What are bare metal devices?

A “bare-metal device” is a device that hosts an application. In layman’s terms, it’s a physical device that is completely dedicated to running a single dedicated application, which for example, could be a “thermostat control program”. In the days before PCs, this was how computers worked.
