Hello Neel Shah,
Please check the jumper settings firstly referring to "3. Configuration of the PNEV7462B board" of UM10883 - PN7462AU Quick Start Guide - Customer Board.
Then try to create a new workspace by MCUXpresso and import the NFC reader library as well as the sample projects, and try to download again.
Please kindly let me know if the problem is still there.
Have a great day,
Kan
