Has anyone had a problem with with calibrating the internal RC oscillator on a mega 164P using a JTAG ICE MkII in ISP mode? The calibration firmware successfully programs and the calibration routine starts, but fails. I put a scope on MISO and it sits high during the whole process, on a successful calibration it is supposed to pulse low 4 times.
I'm using AVR Studio 4.13 SP2 with the latest calibration firmware from Atmel's site.
I've put a m16 on the same board and it calibrates fine, so I don't think the problem is in the hardware.
I've been trying to get this working for 2 days, so any insight would be very appreciated!
