build.sh runs inside Docker (mounted at /scripts/build.sh via docker-compose volume). flash.sh runs on the host and takes the project name as an argument, auto-detecting the .uf2 file. Usage: cd color_switcher && docker compose run --rm pico-build bash /scripts/build.sh cd .. && ./flash.sh color_switcher

# flash.sh — Flash Pico firmware for a given project
|
|
# ============================================================================
|
|
# Runs on the HOST macOS (not inside Docker) because it needs access to
|
|
# /Volumes/RPI-RP2, the USB mass storage mount that appears when the Pico
|
|
# is held in BOOTSEL mode.
|
|
#
|
|
# Usage:
|
|
# ./flash.sh <project>
|
|
#
|
|
# Example:
|
|
# ./flash.sh color_switcher
|
|
#
|
|
# The script finds the .uf2 file in the project's build/ directory
|
|
# automatically — no hardcoded firmware name needed.
