Yes I can post, but the issue is that in both cases PCBs are different - it is thru hole (and big) components in one case, and small and SMD components in another, but giving the same issue. I think, maybe this is RMW issue somehow? because say PORTA.1 is used as ADC IN, but PORTA.2 is used as a digital output, has MPSA42 transistor connected to it's pin.
