Hello Nathan, thank you for your answer. My board bring up properly, it cannot start mfrc522 because the sensor is returning 0x00 in mfrc522_getfwversion. I used logic analyzer and the signals is ok, look image below: [image: image.png]
Step by step I see exactly what happened in the debug console, I am reading 0x00 from the sensor. In this way, mfrc522 is not started. I don't have any other idea than sensor fake board.
