Hi Gang,
I really frustrated with my ATMega8515s tonight.
I am using a Compaq 1.8 Ghz, with XP Home, GiveIO, Avrdude 4.3.
I have 26 devices in front of they all have the same date code. They are all
fresh from the distributor.
I have a vector board with an Emulation Technology LQFP zif socket on it. It
also has a +5v power supply, a reset circuit, a 8mhz crystal with two caps and
10 segment bargraph LED.
20 devices program satisfactorily, 6 fail repeatedly.
I have LEDs connected to the MOSI, MISO, SCK, Reset, +5V, PA0-PA4.
I can insert any part and try reprogram it. The failures always fail and the
pass always pass.
Observing the LEDs on the failures I never see any change of state on the
MISO line. Pin 2, PB6. I do see it on the devices that pass.
The command and program output is shown below.

avrdude done. Thank you.
Does anyone have a clue why 20% of my devices are failing?
