[En-Nut-Discussion] Dead Ethernut

[Kevin Rock]

Hi Pete,
   Your problem sounds much like what I had a few months ago.  I tried AVR Freaks and only got smart ass remarks.  I tried this list and got no response at all.  I figured I had blown the board so I ordered another one and a few other dev boards with the Atmel 128 chip on it.  The Mavric board showed me my code was fine but the programmer code from the AVR studio was flawed.  I had tried flashing the programmer but that changed nothing.  I still could not program my Ethernut board.  It was frozen.  Then the folks who sold me the Mavric board helped me get it working with avrdude.  Now I use the AVR studio environment to write code and debug but program the boards with avrdude.  I have not touched my new Ethernut board at all.  I am programming the old one now with avrdude and there is no problem.  I just avoid using the programming software from AVR studio and I'm fine.  You may want to check the fuses though.  You may have reset one and locked the system.  
   Good luck,
      Kevin.

We have an ethernut that we can program, but does not respond to either the serial port or the the ethernet port. It was working, and we had programmed it several times. 

The red and green lights come on, but not the yellow.?

I have reloaded basemon.hex, but it does the same: no response on the serial port or the ethernet.

It does respond to the JTAG interface (using avr-dude). We can upload hex files, but they appear not to execute.

Any ideas?
Thanks,
Pete Allison
