The ARM Cortex-M processor family is designed for embedded applications requiring high performance and low power consumption. Cortex-M processors are based on the ARMv7-M architecture and include features like Thumb-2 instruction set, NVIC for interrupt handling, and SysTick timer for OS task scheduling. When power is first applied to a Cortex-M based microcontroller, it goes

The bkpt instruction in ARM stands for breakpoint. It allows you to halt the execution of a program at a specific point and examine the state of the processor and memory. This is useful for debugging purposes. What is a Breakpoint? A breakpoint is an intentional stopping or pausing place in a program, put in

The ARM boot process refers to the sequence of steps that an ARM-based system goes through from the moment it is powered on until the operating system is up and running. This process is complex and involves coordination between hardware and software components. Power On When an ARM system is first powered on, the processor

The ARM Cortex-M7 is a high-performance processor core designed for embedded applications that require high computational power and real-time response. As part of the Cortex-M series of ARM processor cores, the Cortex-M7 is optimized for low-power operation while still providing impressive performance capabilities. Some key features and capabilities of the Cortex-M7 core include: Architecture Overview

ARM microcontrollers are small, low-power microprocessors based on the ARM processor architecture.
