I think that is the problem.  The data register has an initial value of
0x00 after reset.  When you configure a GPIO as an output first, the
initial value of 0 gets driven on the pin.  The pin will continue to
a zero until the corresponding data register bit is written with a 1.
Switching the order should solve your problem.
