How can I tell if my board is an X2 or an X3?  I'm trying to work on QSPI boot, which is not supported on X2, according to the QorIQ SDK doc.

The X3 has U44 in DQFN14 package near J12 (JTAG header).

Thanks.  I have a U44, but I can't tell yet if it's DQFN14.  What would it be if I have an X2 board?  Do you know?

The X2 does not possess U44.

Got it, thanks.  Looks like X3 for me.
