Tools and Techniques to Debug an Embedded Linux System

In this talk we will learn how to use different tools and techniques to debug an embedded Linux system. There are several techniques to debug an embedded Linux system that can be applied in both user space and kernel space. Depending on the problem, you may need different tools, like addr2line for crash dump analysis, GDB for interactive debugging, ftrace for kernel tracing, valgring to catch memory-related issues, gprof for application profiling, etc. In this talk, we will learn how these and many other tools and techniques can be applied to improve the quality and find/fix bugs faster on an embedded Linux system.

Talk presented at OSS Latin America 2022.
