Even worse, post-mortem analyses are yet harder when these events occur randomly and it is apparently impossible to trigger them in a controlled fashion. In spite of thorough testing at qualification stage, unfortunately, these situations may even occur when the system has already been deployed on the field and is used by end customers making the analysis amazingly troublesome.
Several techniques are available for post-mortem analysis. Software tools, hardware tools, or a combination of both can be leveraged. This article is the first of a series of Technical Notes (TN) describing in more details some of these techniques. Interestingly, some TN's refer to real-world cases in for which DAVE Embedded Systems deployed its expertise to support several customers reporting on-field failures they were unable to analyze with traditional debugging tools and approaches. In these cases, often information reported by customers are necessarily so limited and fragmented that is generally impossible to determine a priori if the root cause is software or hardwarerelated. Thus, no assumption about the root cause domain can be made and engineers need to be very open-minded to consider every possible cause. == Articles in this series ==TBD
