# Smoke test: run the merged blink binary in qemu-system-riscv32 -M esp32p4.
#
# REQUIREMENTS — none of these is true at 2026-05-06:
#   1. Espressif QEMU fork includes -M esp32p4 (see issue #127, status: To Do).
#   2. qemu-system-riscv32 binary is in PATH.
#
# This script will FAIL today. It exists as a reference for Phase B
# (see autosearch/06_recommendations.md). Re-evaluate when espressif/qemu
# adds hw/riscv/esp32p4.c to esp-develop.
