Mentorship Session: Tools and Techniques to Debug an Embedded Linux System

Mentor: Sergio Prado, Consultant & Trainer, Embedded Labworks 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 and kernel oops analysis, GDB for interactive (remote) debugging, ftrace for kernel tracing, valgring to catch memory-related issues, strace/ltrace for user space applications tracing, perf/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.
