[En-Nut-Discussion] Dead Ethernut

[macsmaker at aol.com]

(I've never gotten a response posting here, so I'm not expecting much....)

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
