2.2 Linux driver support

PN7120 NFC Controller is supported under GNU/Linux system using the NXP Linux libnfc-nci software stack (for more details, refer to AN11697 available on PN7120 Product Web Page [5]). The Raspberry Pi and BeagleBone Linux demo images include the complete stack (Kernel mode driver, User mode library and demo application) allowing to demonstrate the NFC functionalities offered by the PN7120.

2.3 Android driver support

PN7120 NFC Controller is supported from the official Android Open Source Project (refer to [7] for more details) with the addition of dedicated patches available through PN7120 Product Web Page [5] (refer to AN11690).

The BeagleBone Black demo image is based on this concept.
