I'm exploring debugging via dW on linux. It looks to me like all the pieces
are there, but I can not make it work. Therefore some questions.
I can enter dW mode using avrdude using this command line:
> avrdude -P usb -c dragon_isp -p t85 -v -U hfuse:w:0x9F:m
I did presume that using this I can go back to ISP:
> avrdude -P usb -c dragon_dw -p t85 -v -U hfuse:w:0xDF:m
But this does not work, it seems that avrdude can not really communicate
with dW:
markus@T60:~$ avrdude -P usb -c dragon_dw -p t85 -v

avrdude done. Thank you.
Any hints/experience on how to get out of dW mode again ?
