Thanks Joerg. Problem solved!!!!
The output I get is a5 a7 9e 9e. Maybe this is correct. I will test this.
For someone elses reference these were changes made in avrdude.conf
Under ATmega 8515 change
memory "calibration"
size = 1;
read
= "0 0 1 1 1 0 0 0 0 0 x x x x x x",
"0 0 0 0 0 0 0 0 o o o o o o o o";
;
to
memory "calibration"
size = 4;
read
= "0 0 1 1 1 0 0 0 0 0 x x x x x x",
"0 0 0 0 0 0 a1 a0 o o o o o o o o";
;
to get the remaining calibration bytes.
Thanks again for helping.
