Hi,
I've build a simple testing board (veroboard version), containing PIC16F872 and a couple of leds. The chip is porgrammed using ICD2 kind of programmer, but the issue is that it doesn't run the code, until I touch one of the OSC pins or ground.
I'm using 20Mhz crystal and 33pf caps. MCLR pin is pulled up with 10K resistor.
Has anybody seen anything like this before?
