PNEV5190B evaluation board quick start guide
4 PN5190 secure firmware update
The PN5190 supports secure firmware update and it provides an easy way to upload
the firmware via the NFC Cockpit tool or by an application hosted on the microcontroller,
which implements secure firmware update functionality.
This document describes the process of how to flash the PN5190 FW to the PNEV5190B
evaluation board. It also explains how to prepare the firmware update software for any
microcontroller connected to the PN5190 IC.
The PNEV5190B customer evaluation board and MCUXpresso IDE toolchain are used
as a reference to describe the functionality.
