Hello, I’m Yun.

This blog is for accumulating long-term valuable content: Embedded Linux, C, AI, research topics, technical practice, study notes, project reviews, tool experience, and periodic reflections.

I aim to make the articles here:

• Honest: recording real problems and their solutions
• Reusable: providing steps, code, and rationale that can be referenced later
• Maintainable: keeping titles, categories, tags, image paths, and reference links clear

Current focus areas:

• Embedded Linux: system boot, driver debugging, rootfs, cross-compilation, and board bring-up
• C Language: pointers, memory, modularization, concurrency boundaries, and engineering-oriented coding habits
• AI: model fundamentals, prompts, agents, AI engineering, and practical toolchains
• Research: topic breakdown, experiment design, paper reading, reproduction experiments, and stage reviews

If you’re also building your own knowledge base or personal site, I hope these notes offer you some reference.
