OK This is one for Nigel probably, as he wrote WPP, but if any info from anyone is appreciated.
I am programming one of my SMT boards, this has always worked fine but this time its bringing up errors.
The programmer still works with my DIP pics, I dont have another SMT board here at the moment to try...
Here's what happens...
Sometimes it writes to program memory but then fails verification at adress 0x00
Sometimes it stops straight away without writing to memory.
When i read from the chip it has the code on the chip, but the fuses and oscillator options are all wrong.
If anyone can offer help on this, such as what part of my circuitry may be at fault, or the nature of the error, I would greatly appreciate it.
