No program response, including config instructions

[pedja089]

First post your code here...
Clkout is FOSC/4, so OSC is set to 8MHz, you should get 2MHz on pin.

[MillicentBear]

Analyser shows the clock "ticking" at 1MHz, corresponding to the default 4MHz/4, not the 2MHz I intended to set.

The analyser shows GPIO.5 going Hi and staying there until the power is turned off.

Power is 3 x 1.5 AA cells.
