AW: [En-Nut-Discussion] Ethernut programming problem

[Oliver Schulz]

Hi Pete,

had nearly the same problem, when I switched from ethernut 1.3 to 2.0.
Please make sure, that your power supply for the ethernut board delivers
at least about 500mA (better 800mA).

This is important, because the programmer is usually powered from the
ethernut board.

Hope that helps,
Oliver.

Hmm, I've just had a slightly different programming failure using 
avrdude.  After the 'Writing' progress bar got to 50%, it produced the 
error message:
     avrdude: serial_recv(): programmer is not responding
and then exitted.
The LED on the programmer continued to pulse red/green until I removed 
power from the Ethernut.

Regards,
Pete Allinson
