Hi,
I tried AVR053 application note. I tried to calibrate ATmega2560 internal RC oscillator 8MHz using JTAGICEmkII.

I just compile the code and run the batch file.

When I measured the CKOUT pin before calibration, I got 8MHz. After the calibration is completed successfully, when I measured the CKOUT pin, I got 12MHz :roll:

I don't know why it is measured as 12MHz.? any input?

The AVR053 app note works fine. You need to do a bit of fiddling about to change MCU model etc.

It sounds as if you have calibrated for 12MHz. i.e. you have set wrong macros in the batch file.
