nfc-list produces "nfc_initiator_init: Timeout" #528

Closed mvanaltvorst closed 5 years ago

mvanaltvorst commented 5 years ago

I'm on the latest commit, version 1.7.1, Arch Linux. I configured my compilation with ./configure --with-drivers=pn532_uart --sysconfdir=/etc --prefix=/usr --enable-serial-autoprobe.

LIBNFC_LOG_LEVEL=3 nfc-list produces the following output:

nfc_initiator_init: Timeout

As you can see libnfc communicates with the PN532 at first, but then it times out. I've checked my connections and I'm pretty sure they're fine. What am I doing wrong?

Fixed by supplying 5V to VCC instead of 3.3V.
