I've been using Studio 4, a Jtag ICE mkII and an STK500 (with a STK501 fitted) to work with a ATMega128 for a while now because this is what I was originally supplied with. That device is nice because it has full JTAG and it's therefore easy to do things like programming the fuses.
I've now got some DIP samples of the ATmega168 device I actually intend to use so removed the STK501+ATMega128, fitted the ATMega168 into socket SCKT3200A2 and used the flying wires on the JTAG ICE header to connect to the (green) 6 pin ISP block on the STK500.
This let me program the DWEN fuse to enable DebugWire and I've been happily using that fine to debug.
But I now want to change some other fuses in the device and simply cannot find the place in Studio 4 where I can do that.
I can bring up the JTAG ICE mkII options and click the "Disable Debugwire" button to switch back to ISP programming and I can also switch the other way to go back to DebugWire by loading a file to debug and it pops up to say "DebugWire not active - do you want to switch it on now". That works too. So I can switch between the two.
But I cannot see how to program any of the other fuses in the device (clock sources etc.) with the combination of Studio 4, JTAG ICE mkII, STK500 and the AtMega168 part.
Can anyone explain what I'm missing?
Do I need to configure things for "high voltage programming"? If so, how?
