In this course, we will delve into the world of embedded systems engineering using ARM microprocessors. Our focus will be on the System-on-Chip architecture prevalent in the ARM world, beginning with the fundamentals of low-level firmware. We will explore the intricacies of the boot process, configuring and compiling its various components entirely from scratch. The result will be a streamlined Linux distribution, encompassing the kernel, rootfs, and initramfs.
