研究方向

Locate all occurrences of `zephyr cc option( Wno pointer sign)` in the Zephyr CMake files. Remove this option, then compile the project to identify warnings about signed/unsigned pointer mismatches. Fix each warning by adding appropriate casts or changing variable types. Comments on the issue (4 comments) may provide hints. Since no PRs are linked, a good approach is to start with one subsystem and submit a PR with incremental fixes. The Zephyr codebase is large, so focus on a specific area like kernel or drivers.
