Flashing

Prerequisites

ESP-IDF v5.x installed and exported (get_idf)
USB cable to the DevKit USB port (USB‑JTAG / serial)
PN532 module wired per PINOUT.md

Steps

Build the web assets (embeds into SPIFFS):

cd web && npm install && npm run build:fw

Configure & flash:

cd firmware
idf.py set-target esp32s3
idf.py menuconfig   # set PN532 transport + GPIOs
idf.py build flash monitor

Connect to AP PN532-Toolkit / nfc-toolkit, browse to http://192.168.4.1 or http://pn532tool.local.

SPIFFS / UI missing?

If firmware/data/ is empty, the device serves a placeholder HTML. Always run npm run build:fw before idf.py build if you changed the UI.

Flash size

partitions.csv assumes 8MB flash. For 4MB, shrink factory / OTA / storage regions and disable dual OTA if needed.
