Embedded Bootloader Development from Ground Up™

Essentials of Custom Bootloader Development

6+ hours | Complete Source Code Included

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 linker scripts 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.

Here's a sneak peek at what you can expect to learn:

A little about me : Israel Ninsaw Gbati

Some of you may have taken some of my embedded systems courses from other online platforms.

This is my private channel.

I have been writing embedded firmware for years, I have built embedded devices like consumer products and robotic arms.

Till date I have

trained over 100,000 students in embedded

firmware development online till date

...including third year undergraduate university students in-person.

If you have taken any of my courses before you will know I start from the absolute basics, I do not assume that the student has any prior knowledge of the topic under discussion. You will also know that by the end of the course you understand the functions of every register used in developing the particular firmware or driver.

This method is the same for all of my published embedded systems courses.

Our courses have been reviewed by 1000+ students
