From Hardware to Linux - A Step-by-Step Guide

Explore a comprehensive step-by-step guide from hardware design to a fully functional Linux system in this informative conference talk. Learn about initial hardware design considerations that simplify the bringup process, including designing for testability and incorporating debugging features like accessible test points, serial consoles, and JTAG interfaces. Discover the bootloader phase and how to utilize JTAG for early debugging to achieve text output and console access. Delve into the transition to the Linux kernel, exploring strategies such as JTAG for early kernel debugging and the use of printk and KDB for later diagnostics. Examine the final phase involving the root file system and userspace tools for peripheral bringup. Gain insights into userspace diagnostic and debugging tools essential for successfully launching a Linux-based system.
