Description

Get ready to dive into the exciting world of bootloader development with this beginner level course of our bootloader development series on STM32 microcontrollers.Throughout this beginner-friendly course, you will explore the fundamentals of bootloader development, from the build process to the memory model and beyond.Through a number of bite-sized modules, you will learn how to create custom bootloaders that enable you to take control of your firmware and unlock the full potential of your STM32 microcontrollers. You will gain understanding of the embedded build process, the STM32F4 memory model, and the critical role of linkerscripts and the linking process.In addition to theory, you will get hands-on experience working with the linkerscript; creating custom sections, and defining memory regions etc.But that's not all - you'll also have the opportunity to get further hands-on experience with  linkerscripts and design and develop your own bootloader. And in the final project, you'll apply your newfound knowledge to create a multi-slot memory system  bootloader which is capable of storing multiple firmware applications on the same microcontroller, implement a push-button trigger for entering bootloader mode, and develop a simple communication driver for selecting different firmware  applications stored in memory.By the end of this course, you'll have the skills and knowledge needed to confidently develop custom bootloaders for STM32 microcontrollers, opening up new possibilities for firmware updates, recovery, security, and customization.With the flexible online format, you can study at your own pace, from anywhere in the world. Plus, we offer a 30-day money-back guarantee, so you can enroll with confidence.
