I verified the power supply and that the CPU's oscillator is driving the crystal. It'll be a bit longer before I can test the other portions of the system. I used solder paste for the first time when assembling this, which went really well. It made the LQFP 48 and even the QFN 32 packages a breeze. The latter I had expected to be trick or even beyond my capabilities because it doesn't have any pins as such, just pads on the bottom. I just put a bead of solder paste all around the pads on the PCB and used a hot air gun to melt it and it seemed to work fine. I won't know for sure until I have software running on it, of course.
