Resource Optimization (Low-End Systems)

Purpose

Guide agents through flash and RAM optimization on constrained devices: compiler size flags, linker map analysis, stack usage measurement, dead code elimination, and size-vs-speed tradeoffs — for bare-metal and small RTOS images.

When to Use

• Firmware exceeds flash budget
• Stack overflow in production only
• Choosing -Os vs -O2 on MCU
• Finding unexpected .rodata or .bss growth

Workflow
