Tom Dunkle updated the graphics debugging documentation in the madeline-underwood/arm-learning-paths repository, focusing on deprecating the outdated Graphics Analyzer and guiding developers toward Frame Advisor and RenderDoc as preferred tools. He enhanced the mobile learning path by adding a direct link to the RenderDoc Reference Guide, streamlining the transition for developers adopting new debugging workflows. His work centered on Markdown-based documentation, resource linking, and version-controlled contributions, ensuring that guidance remained current with ARM Performance Studio’s supported tools. The updates addressed developer confusion and improved resource clarity, though the scope was limited to documentation without direct code or bug fixes.
