Should the PN532 oscillator work at the start?

I made a prototype based on the following board:



I tried to communicate via RS232 with PN532, but I don't get any response. Check the connections and voltage levels and everything seems fine, except that I don't see the oscillating voltage at the terminals of the crystal with my oscilloscope.



I read that at the beginning the device is in low power consumption. Should it be normal in the absence of oscillation?


Thanks in advance for any comments or suggestions-
