Thanks Richard.

I really do not care if the clock will be available on clk2 out or not. I'd rather prefer to keep that pin as an I/O. But anyway. The thing won't run. Or at least at the expected speed.

According to the PIC18F4550.INFO file, if I want to keep an I/O function on the clk2 pin, and also have PLL enabled the ECPLLIO_EC is to be used.

I wonder if the order of configs play any role. I'll check it later today.
