Linker Script Architecture

🧠 The Core Concept: LMA vs. VMA

A Staff Engineer must distinguish between where code “lives” and where it “runs.”

• LMA (Load Memory Address): The address in Flash where the data is stored permanently.
• VMA (Virtual Memory Address): The address in SRAM where the data is copied so the CPU can read/write to it during execution.

🧱 Memory Map Definitions

In shared/linker.ld, I defined the physical boundaries of the STM32L475VG:

```ld MEMORY { FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 1024K SRAM (rwx): ORIGIN = 0x20000000, LENGTH = 96K }
