Can Cortex-M Processors Run Linux?

This article introduction

What is the core difference between microcontrollers and application processors? Is it the difference in core frequency? Or the support of the Linux system? Or the architecture of the processor? This article will briefly introduce the NXP Cortex-M series as an example.

1. Positioning of Cortex-M

The architecture of the processor defines the instruction set (ISA) and the programmer model of the processor based on this architecture. In simple terms, application software under the same ARM architecture is compatible. From
