1. Introduction
This document gives a description on how to get started with the OM5578 PN7150 NFC-
Controller SBC Kit on BeagleBone Black platform. This document provides a step by
step guide to the installation procedure of the hardware and the software. Finally, it
shows PN7150 NFC Controller functionalities through demonstration application.
1.1 OM5578/PN7150BBB demo kit
OM5578/PN7150BBB kit is a high performance fully NFC compliant expansion board for
BeagleBone Black (refer to [1] for more details). It meets compliance with Reader mode,
P2P mode and Card emulation mode standards. The board features an integrated high-
performance RF antenna to insure high interoperability level with NFC devices.
The demo kit is comprised of a PN7150 NFC Controller Board, a dedicated interface
board, and a NFC Sample Card.

The demo kit is fully described in UM10935 document [4].
1.2 Linux driver support
PN7150 NFC Controller is supported under GNU/Linux system using the NXP Linux
libnfc-nci software stack delivered through public GitHub repository
https://github.com/NXPNFCLinux/linux_libnfc-nci (for more details, refer to AN11697 [2]).
1.3 Android driver support
PN7150 NFC Controller is supported from the official Android Open Source Project (refer
to [5] for more details) with the addition of dedicated patches (refer to AN11690 [3]).

2. Quick Startup on BeagleBone
2.1 Required items
• BeagleBone Black [1]
• MicroSD card of at least 4 Gb (8 Gb for Android demo image)
• 5V adapter to power the BeagleBone (Note:Micro USB cable doesn’t provide the 5V
required by the antenna supply of the OM5578/PN7150S board. Without it no RF
field can be generated by the OM5578).
• USB Keyboard
• USB Mouse
• USB Hub to connect both Mouse and Keyboard to the BeagleBone
• HDMI cable to connect to a Monitor / TV
• Computer (running Windows, Linux or Mac OS X) for MicroSD card installation
• BeagleBone demo image file (see [6])
2.2 Hardware setup
First of all, assemble the PN7150 NFC Controller Board with the BeagleBone Interface
Board.

2.3 Software setup
Prepare a MicroSD card, with the downloaded BeagleBone demo image (see [6]),
following the installation guidelines. First extract the “.img” file from the archive, then
flash it on the microSD card according to below guidelines.
2.3.1 On Windows
Insert the MicroSD card into your computer (note the device drive letter), and using
Win32 Disk Imager, write the image into it:

2.3.2 On Linux
Insert the MicroSD card into your computer and determine the device node assigned to it
(ignore the device number; e.g. /dev/sdb, not sdb1):
$ sudo dmesg | tail -20
$ sudo dmesg | tail -20
[95300.848154] usb 2-1: new high-speed USB device number 33 using ehci-pci
[95300.983859] usb 2-1: New USB device found, idVendor=14cd, idProduct=6d00
[95300.983872] usb 2-1: New USB device strings: Mfr=1, Product=3, SerialNumber=2

Then, unmount the device node using following command:
sudo umount /dev/devicenode
Finally flash the image to the device node using following command:
sudo dd if=path_to_image_file.img of=/dev/devicenode bs=1M
2.3.3 On MAC OS X
Using PiFiller (see https://learn.adafruit.com/beaglebone-black-installing-operating-
systems/mac-os-x), select the image file then insert the MicroSD card into your computer
to flash it.

2.4 Linux NFC demo application
2.4.1 Application details
The demo application is part of the Linux libnfc-nci stack available on public GitHub
repository https://github.com/NXPNFCLinux/linux_libnfc-nci. The related source code can
then be found there (more details in document AN11697 [2]).
2.4.2 Starting Linux NFC demo
Insert the MicroSD card in the BeagleBone. Connect HDMI Display, mouse and
keyboard via the USB Hub. Finally supply the BeagleBone using 5V adapter.
The BeagleBone boots and displays the bone-debian GUI:
Fig 6. bone-debian GUI
Open a terminal and browse to the Linux libnfc-nci stack directory (refer to chapter 1.2 for
more details about the Linux NFC software stack).
$ cd ~/linux_libnfc-nci
The application requires parameters to run:
$ ./nfcDemoApp <OPTIONS>
You can get the parameters details by launching the application help menu:
$ ./nfcDemoApp –-help

Fig 7. Linux demo application commands
The demo application offers 3 modes of operation:
•Polling: continuously waiting for a remote NFC device (tag or peer device) and
displays related information
•Tag writing: allows writing NDEF content to a NFC tag
•Device push: allows pushing NDEF content to a remote NFC peer device
2.4.2.1 Polling mode
When in this mode, the application will display information of any discovered NFC tags or
remote NFC device.
It is reached starting the application with “poll” parameter:
$ ./nfcDemoApp poll
