flash.ps1

# couchlink flash wrapper
#
# Detects a Pico in BOOTSEL mode and copies the matching firmware UF2
# onto it (couchlink-pico2w.uf2 for the RP2350 board, couchlink-picow.uf2
# for the RP2040 board). Use this when you need to re-flash without
# running the full setup wizard.
#
# Tip: this only flashes firmware. It does NOT push Wi-Fi credentials.
# After a re-flash, use configure-wifi.ps1 to send Wi-Fi to the Pico.
