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?
