The Armmite code doesn't work and cannot work with a 25MHz crystal. You must use 8MHz. Your load capacitors on the 8MHz seem very low, normally 18-22pf seems appropriate. Everything suggests that one of the oscillators isn't running.
Loading over USB or with the ST-LINK uses an external clock so these will work regardless
