## 🔄 Review from Weeks 1-2
This week builds on your GDB and Ghidra skills from previous weeks:
- **GDB Commands** (`x`, `b`, `c`, `si`, `disas`, `i r`) - We'll use all of these to trace the boot process
- **Memory Layout** (Flash at `0x10000000`, RAM at `0x20000000`) - Understanding where code and data live
