PNEV7462B not detecting cards

I am running the BasicDiscoveryLoop on MCUXpresso to detect MIFARE cards using a PNEV7462B and a LPC-Link 2 debugging board. The code compiles well, as a matter of fact, I am able to flash the binary file created into a Kroneger reader (with the proper setup) and it detects the cards well. This makes me think that there is something wrong in my PNEV7462B setup. I changed the CRP_00.BIN and DRP_00.DAT files way back for a different purpose, which makes me think that is the issue. I updated the .DAT file with the file called user_ee.bin from the PN7462AUPspPackageFull-v05_19_00 package, but that did not help. Is there somewhere I can get the right files? It could maybe be something else? I am attaching a picture of my setup so you can see how I have the jumpers arranged.


Thank you in advance.
