NXP NFC Reader PNEV512R with nxppy not working with Raspberry Pi 4

[AlexanderLaix]

Please answer these questions as part of your new issue.

Which version of Python are you using?

Python-3.6

Which OS and version are you running?

Raspbian GNU/Linux 10

Is SPI enabled?

Yes --> and already checked!

Are you trying to read/write a Mifare Classic card? (This is currently unsupported)

Also

Hi,
the NFC card reader PNEV512R (https://www.nxp.com/products/rfid-nfc/nfc-hf/nfc-readers/explore-nfc-exclusive-from-element14:PNEV512R) does not work with my new raspberry pi 4.

Kernel:

Linux AlexPi 5.4.51-v7l+ #1333 SMP Mon Aug 10 16:51:40 BST 2020 armv7l GNU/Linux
Release:
PRETTY_NAME="Raspbian GNU/Linux 10 (buster)"  
NAME="Raspbian GNU/Linux" VERSION_ID="10" 
VERSION="10 (buster)"
VERSION_CODENAME=buster
ID=raspbian

For installing the needed software I followed this manual: https://github.com/svvitale/nxppy
Installation was without any fails.
But even the instantiation of Mifare raises an exception.

Python Code:

import nxppy
mifare=nxppy.Mifare()

Exception:

nxppy.InitError: Nxppy: Unknown Error from Undefined Component

    The above exception was the direct cause of the following exception:

    Traceback (most recent call last):
      File "nfc.py", line 3, in <module>
            mifare=nxppy.Mifare()
    SystemError: <class 'nxppy.Mifare'> returned a result with an error set

The SPI was switched on of course. ^^ And I tested the interface with the loopbacktest: https://elinux.org/RPi_SPI
So SPI is working.
On my Raspbarry Pi 3B+ everything works fine. Now I am looking for a solution to fix this problem.
Do you can help me out here?

Thanks a lot
Alexander
