Hard fault while running "NfcrdlibEx3_NFCForum" example

[lucadici]

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?

The NFC reader library version I'm using is v4.040.05.011646

Hi Luca Dici,

Actually this library is designed for lpc1769, so if you changed it to lpc1766, there should be changes in BSP files for lpc1769, if this issue is still there after you change the MCU settings as below:

you might have to ask help from the lpc community: LPC 

Have a great day,
Kan
