Linker Script | Embedded Systems | Understanding Linker Script
Most developers treat the Linker Script and Startup Code like a "black box"—if the code compiles, they don't touch it. But if you want to master Embedded Systems, you need to understand exactly how your hardware wakes up and where your code actually lives.
In this deep dive, we’re breaking down the bridge between your C/C++ source code and the raw binary sitting in Flash. No fluff—just the essential keywords and logic you need to control your memory layout.
🔍 What We Cover:
The Boot Process: From Power-On Reset (POR) to main().
Linker Script Keywords: Understanding ENTRY, MEMORY, SECTIONS, and the significance of KEEP.
Memory Mapping: How .text, .data, .bss, and .rodata are mapped to VMA and LMA.
Startup Code Essentials: The Vector Table and the crucial "copy-loop" that initializes your RAM.
Symbols & Alignment: Why ALIGN(4) is your best friend for avoiding hardware faults.
