Hands-on Embedded Operating System Development from the ground up
What you'll learn
Learn how to build an embedded system from the ground up on the bench. This will give you a great insight into the target platform, but is not mandatory
Learn how to program a microcontroller from scratch by setting up wiring, clocking, connecting the programmer, and flashing binary applications to the chip
Get a deep insight into what an operating system is, when you need one, and how it works on embedded platforms
Understand Kernels, Multitasking, Context Switching, Scheduling, Critical Sections, and Task Synchronization from a practical perspective
Understand CPU Architectures in general and how to choose a target CPU. Deep understanding of the MIPS32 Arch internals, like Registers and Memory Layout
Programming of Advanced Applications for the Microchip PIC32 (MIPS32) microcontroller
Develop Board Support Packages (BSP) for a Target Platform
Deep and practical understanding of data communication over the SPI and I2C busses, as well as serial communication via UART modules (including USB-to-Serial)
Learn how to develop a Preemptive and Cooperative Kernel based on CPU-specific assembly code for Task Context Switching
Learn how to provide efficient internal services for Time, Task, and Memory Management
Learn how to create Inter-Process Communication (IPC) with Mailboxes and Message Queues
Get a deep understanding of - and learn how to implement - Real-Time Constraints in order for an operating system to be considered an RTOS (Real-Time OS)
Understand the Priority Inversion problem and learn how to implement specific countermeasures
Learn Device Driver development. We will develop drivers step by step for our Target Platform's peripherals, such as the display and the MicroSD card
Interfacing User Application to the OS
Understand how to write a binary image to the Target Platform's Program Flash at runtime, and create a USB/UART Bootloader
Learn how to make a Porting of the OS, making it executable on different CPU Architectures
Understanding of the Target Platform's Electrical Schematic and PCB Layout (optional)
Requirements
Basic C programming skills are recommended but not mandatory. The code implementation will be performed hands-on, with explanation in real-time. No particular prior knowledge is required. If you have any questions, simply drop me a message: I will answer to you.
Description
In this course you will learn how to create an Embedded OS, really from the ground up. You will be guided step by step in the creation of each and every technical software module composing an embedded operating system, as well as in the development of your own target device on the bench (optional: you can use a free simulator or a ready-to-use Starter Kit), starting with basic electronic components and an industry-standard processor.You will learn how to create device drivers step-by-step for real hardware components like displays, SD card storage, Wi-Fi, Inertial Movement Units (IMU, i.e. accelerometer and gyroscope), USB communication, analog Joysticks, thermal camera modules and more.By the end of this course you will master system-level programming in the assembly and C languages, as well as the technical processes governing the interaction between CPU and memory. Thanks to the numerous hands-on experiences and practical demonstrations, you will develop the ability of gaining full control on the machine by manipulating CPU registers, stack, instruction pointer, return addresses, and much more. At the end of the software development part, you will learn how to create a porting to another architecture, like x86.Although the hardware development part is optional, if you have access to an electronics lab you will also develop the ability of prototyping your circuit, designing and assembling your own target PCB (Printed Circuit Board).
