The eBook describes a real world case study involving a SoC with Linux, but the methodology could be applied to software for Intel multicore processors as well.
“The problem is usually these bugs manifest themselves in one place in the code, but the real root cause is somewhere totally different, quite possibly in a process running on a different core entirely,” said Larry Osborn, an ASSET senior product manager and author of the new eBook. “As a result, applying multiple tools – both trace and static analysis – is the best way to get the visibility that the engineer needs. This case study looks over an engineer’s shoulder, if you will, and outlines a step-by-step approach to trace back to the real root cause in a fraction of the time.”
Titled “Trace Accelerates Debug Analysis in Complex Linux Systems,” the new eBook shows how the root cause of a core dump bug was quickly found in code running on another core. The eBook is free and available for downloading now from the ASSET InterTech website in the eResources centre.
