Widget Feature QEMU Code Size Report¶

Commit: 1fe189eb
Date: 2026-05-21T16:08:32.440547
Build target: APP=HelloSizeAnalysis APP_SUB=widget_feature_probe PORT=qemu CPU_ARCH=cortex-m0plus
Measurement method: compile a dedicated widget probe app, then rewrite the app-local probe config header to force-link a real widget or widget set.
Scope: widget-level static qemu ELF sections only (.text/.rodata/.data/.bss).

Notes¶

This report answers how much ROM and RAM a real widget or widget set costs to bring in.
The probe uses real widget init_with_params and setter paths rather than canvas-only stand-ins.
Widgets share base/view/theme/canvas paths, so widget-set totals must not be computed by summing single-widget deltas.
