Hard fault while running "NfcrdlibEx3_NFCForum" example

Hi all,

I'm using PN512 with LPC1766. I have ported to my board all the projects belonging to the nxp reader library demo app set (e.g. NfcrdlibEx2_AdvancedDiscoveryLoop).

All of them works fine, except for example "NfcrdlibEx3_NFCForum". Even if I disable both SNEP client and SNEP server and I don't interact with cards or smartphones, running the example results in a Hard-Fault of the MCU.

A strange symptom is that at a certain point the stack seems to detect a card:

 

/////
 NFC Forum Example:
 
 Multiple technology detected:
     Type A detected...
     Type B detected...
    Resolving selected technology

/////

 

But actually no activators/targets are in proximity of the antenna!

Is this a known issue for anybody?
