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:

Step by step I see exactly what happened in the debug consol
If I understand correctly, something is failing when trying to bring
up the RFID sensor?
Does the board start up if you remove support for the sensor?
Do you have oscilloscope or logic analyzer to verify signals are being
sent/received between microcontroller and sensor chip?
Do you have a debug
Hello All,
I added stm32f4discovery board mfrc522 support, however it is not working,
probably my cheap board. Can someone with a mfrc522 board share with me
nuttx debug output? So I can consider my port ok or find issues on my side.
