just wanted to throw in that i'm successfully burning bootloaders to atmega168s using an mkII + an arduinoNG on an Intel Macbook running 10.4.9
thank you very much for this feature. if it does not work for anyone and you're sure that your mkii is not dead, check those 3 things mentioned before:
- arduino has to get power from an external source (wall plug)
- set the power source jumper on your arduino accordingly
- plug-in the ICSP-cable correctly.
if the programmers shows the green light (instead of red or orange or blinking or something ) the hardware part should be fine. Start the arduino application now and begin burning your bootloader (or sketch soon :-).
the arduino app seemed frozen when i did it the first times, not telling me something new for a couple of minutes, just a "burning bootloader". the process takes something like 5-10 minutes on this machine, but it works. After some lightshow, the programmer shows the green light again, and arduino tells me "Done burning bootloader". No other messages in between, which you just have to know.
