I am trying to debug why my Pi 3 is not able to communicate with PN532 NFC breakout.

I have a couple of library used to test it (libnfc, nfcpy, and NPM PN532), I am able to test these libraries to be working in Raspberry Pi 1 A/B+
But, when I use the same SD card in my Raspberry Pi 3, it is not working.
I'm pretty sure that all of the configurations are not changed when I switch the SD card back and forth.

Does anyone encounter this error in their new Raspberry Pi 3?

**Note:**

Error in libnfc:

```
pn53x_check_communication: Success
error   libnfc.driver.pn532_uart    Unable to transmit data. (TX)
lt-nfc-poll: ERROR: Unable to open NFC device.

```

nfcpy:
Keeps idling in this message:

```
[nfc.clf] searching for reader on path tty:AMA0:pn532

```

NPM PN532:
Keeps idling in this message:

```
