MFRC522 not working on RPi 4
See original GitHub issueHi, I’m getting the following error using my SD card that works fine in a Raspberry Pi Model 3, if I put it into a Raspberry Pi Model 4:
WARNING: Hardware auto-detect failed, running in raspi-3 mock mode
And consequently the card detection does not work. Any idea what this could be related to? Thanks

Finally got it to work. Unimaginable but the cables were the problem! Really strange that the same cables and the same MFRC522 module were working with a RPi3 but not a 4. Changed the cables and suddenly all worked. Thank you!
generally by running the examples https://github.com/firsttris/mfrc522-rpi/tree/master/test. i mean you could add some console.log here and there. that would be a very easy approach for debugging.
