Mastering Zephyr RTOS with DeviceTree and Board Bring Up

<div>Note : Instructor is still adding lectures to this course.&nbsp; Please check the curriculum above.</div><div><br></div><div>### Learn Zephyr RTOS from the ground up with a clear, structured foundation path ###</div><div><br></div><div>The embedded industry is shifting. Zephyr RTOS, backed by the Linux Foundation, is rapidly becoming the default choice for production IoT and embedded products. Nordic, NXP, Intel, STMicroelectronics, and dozens of other companies are building their ecosystems around it. No other RTOS brings together a unified build system, DeviceTree based hardware abstraction, and a porting workflow that works across MCU vendors in a single codebase. If you are an embedded engineer and you do not know Zephyr yet, you are falling behind.</div><div><br></div><div>This course turns you into the engineer who can take any Zephyr supported MCU, write DeviceTree for it from scratch, port it as a custom board, and build real applications on top of it. Not by copying from samples or following a pre-configured dev kit tutorial. By understanding the complete workflow from the ground up.</div><div><br></div><div>Here is what you will be able to do by the end of this course:</div><div><ul><li><span style="font-size: 1rem;">Set up the complete Zephyr workspace and toolchain on Windows, Ubuntu, and MacOS</span></li><li><span style="font-size: 1rem;">Build and run your first Zephyr applications on QEMU and on real hardware</span></li><li><span style="font-size: 1rem;">Configure your Zephyr project using prj.conf, menuconfig, and Kconfig</span></li><li><span style="font-size: 1rem;">Write DeviceTree from scratch for a custom board and understand every node and property</span></li><li><span style="font-size: 1rem;">Port your own board into Zephyr with the full board directory and configuration setup</span></li><li><span style="font-size: 1rem;">Build real applications using interrupts, threads, and workqueues on your custom hardware</span></li><li><span style="font-size: 1rem;">Debug common DeviceTree and build issues with a repeatable step by step process</span></li></ul></div><div><span style="font-size: 1rem;">Zephyr is not just another RTOS. It is where the industry is heading. Companies building IoT products, wearables, industrial controllers, and connected devices are choosing Zephyr because it gives them one codebase that works across multiple chip vendors. The engineer who can bring up a custom board in Zephyr and write DeviceTree is the one who gets the interesting projects, the better roles, and the trust of the team. That skill set is rare right now. This course builds it.</span></div><div><br></div><div>Most Zephyr resources out there show you how to run samples on a supported dev kit. That is the easy part, and you can do it by reading the documentation. This course teaches you the skills that actually matter at work: writing DeviceTree from scratch, creating your own board files, and debugging the problems that show up when you step off the beaten path. Very few Zephyr courses go this deep into DeviceTree and board porting. This one does.</div><div><br></div><div>This course is built for:</div><div><ul><li>Embedded engineers who want to use Zephyr on their own custom hardware</li><li><span style="font-size: 1rem;">Engineers who tried Zephyr before but got stuck at DeviceTree or board porting</span></li><li><span style="font-size: 1rem;">Firmware developers, students and hobbyists moving from bare metal or FreeRTOS to Zephyr</span></li></ul></div><div><span style="font-size: 1rem;">Note on using AI assisted coding in this course</span></div><div><br></div><div>In the final project, we use AI-assisted coding to build a real embedded application. We deliberately save this for last. First, you build the foundation. You understand how Zephyr works. You can debug issues on your own. Only then do we bring in AI tools to show you how they can speed up your workflow when you actually know what you are doing. Understand first, accelerate later.</div><div><br></div><div>By the end of this course, you will not just know Zephyr. You will be the engineer who can take a bare board, bring it up in Zephyr, and build real applications on it. If that is the engineer you want to become, enroll now. Let us get started.</div><div><br></div><div>Hardware Requirement (for hands on practice)</div><div><ul><li>This course uses the Fastbit STM32 Nano board, based on the STM32F303 microcontroller.</li><li><span style="font-size: 1rem;">You can also follow along using any STM32 or Zephyr supported development board you already have.</span></li><li><span style="font-size: 1rem;">If you want to use the exact board used by the instructor, you can explore the Fastbit STM32 Nano board and follow along one to one</span></li></ul></div>

What you'll learn:

• Write DeviceTree from scratch for any custom board, not just copy from existing samples
• Port a custom board into Zephyr with the complete board porting workflow
• Build real Zephyr applications using interrupts, threads, workqueues, and message queues on custom hardware
• Debug common DeviceTree and build issues using a repeatable step by step process
• Set up the complete Zephyr workspace and toolchain on Windows, Ubuntu, and MacOS
• Understand how a Zephyr application is organized, how the build system works, and how all the pieces connect
• Configure your Zephyr project using prj.conf, menuconfig, and Kconfig the practical way
• Use DeviceTree macros and GPIO APIs to control hardware pins from your Zephyr application
• Configure UART console output for stdout logs and test your application on real hardware
• Use application overlays to customize DeviceTree without modifying the base DTS files
• Implement interrupts and button handling using ISR, DeviceTree nodes, and GPIO callbacks
• Create and manage threads in Zephyr
• Flash and test your Zephyr application on a real custom board
• Add custom properties to standard DeviceTree nodes and access them from your application code
• Set up and use AI-assisted coding with Claude Code for embedded projects
