[avrdude-dev] Avrdude seems to find JTAGICE then hang

[Rick Mann]

I just got avrdude compiled and installed.

I'm not sure what I might be doing wrong. I've got my JTAGICE MkII  
connected to an ATmega32, and I've successfully programmed and  
debugged it with AVR Studio under windows, but on Mac OS X using  
avrdude, it finds the programmer then just seems to stall. Am I  
specifying some interactive mode by mistake?

I just wanted to read the chip (which is already programmed) to see  
if I got back what I had put in.

$ avrdude -p m32 -c jtagmkII -P usb -v -U flash:r:f.hex:s
