X-NUCLEO NFC05A1 expansion board

1. Article Purpose

The purpose of this article is to explain how to integrate the NFC05A1 expansion board with STM32MP157C-DK2, Software will run on Linux on Cortex®-A7. NFC05A1 board is a NFC card reader expansion board based on ST25R3911B for STM32 and STM8 Nucleos.

2. Prerequisites

All the dependencies as per the LINK:Getting_started/STM32MP1_boards/STM32MP157C-DK2 should be installed

2.1. Hardware Prerequisites

• STM32MP157C-DK2 Discovery Kit
• X-NUCLEO-NFC05A1
• 8 GB micro SD card to boot the STM32MP157C-DK2
• SD card reader OR LAN connectivity

4. Software setup- configuration steps

Please follow below steps to first flash the Starter Package onto the SD Card and then customize the platform to run application for X_NUCLEO NFC05A1. Please follow intsructions in the link : STM32MP157C-DK2 Let's start. to flash the Starter Package on the SD Card. In order to set up the development platform, please follow below mentioned steps –

• Download Developer Package and install the SDK in the default folder structure on your Ubuntu 16.04 machine.: Getting_started/STM32MP1_boards/STM32MP157C-DK2/Develop_on_Arm®_Cortex®-A7/Install_the_SDK
• copy the patch file "0065-X-NUCLEO05A1.patch" [ add download link ] to the location where all patch files are placed.
• Build the Developer Package as per instructions given in "README.HOW_TO.txt" file. To ensure that the patch has been applied successfully, you may check in the menuconfig if SPI and gpio interfaces are enabled. Please refer to instructions below -
• “STMicroelectronics STM32 SPI controller” must be enabled. Snapshot below

Near Field Communication ( is a short-range wireless standard for communication over distances up to around 10cm that will enable enhanced services for users of NFC-enabled smart phones. These could include receiving coupons from retailers upon entering a store, or sharing contacts or photos, in addition to making mobile payments and collecting data from medical monitors, smart meters or other equipment containing ST’s dual-interface EEPROM. We produce a wireless memory that can transmit and receive information from the heart of an application to a smart phone containing NFC technology. NFC is expected to become a widely used system for making payments by smart phone in the United States and it is estimated that by 2015, 30.5% (iSupply) of all handsets shipped will contain NFC technology.)
