hello
I'm having the same problem: arduino one brake on the line nfc.begin();
I'm new in arduino and nfc, but I've downloaded pn532 libraries, set pin 1-0 on the board, all the 4 wires are ok (vcc, gnd, sda, scl); the serial speed is set to 115200
in this code:

  #include <Wire.h>
  #include <PN532_I2C.h>
  #include <PN532.h>
  #include <NfcAdapter.h>
  PN532_I2C pn532i2c(Wire);
  PN532 nfc(pn532i2c);
  
void setup(void) {
  Serial.begin(115200);
  Serial.println("Hello!");
  nfc.begin();
  Serial.println("second Hello!");

the serial write just the first Hello!
I can't find a solution... Help me!!

ok
now it works!
in SPI mode (jumper 0 - 1) and SCK MISO MOSI SS VCC GND

thank you all
Massimo
